Bar (unit)
–
The bar is a metric unit of pressure, but is not approved as part of the International System of Units. It is defined as equal to 100000 Pa, which is slightly less than the current average atmospheric pressure on Earth at sea level. The bar and the millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes, use of the bar is deprecated by some professional bodies in some fields. The International Astronomical Union also lists it under Non-SI units and symbols whose continued use is deprecated, as of 2004, the bar is legally recognized in countries of the European Union. Units derived from the bar include the megabar, kilobar, decibar, centibar, the notation bar, though deprecated by various bodies, represents gauge pressure, i. e. pressure in bars above ambient or atmospheric pressure. The bar is defined using the SI derived unit, pascal,1 bar ≡100000 Pa. Thus,1 bar is equal to,100 kPa 1×105 N/m21000000 Ba, notes,1 millibar =1 one-thousandth bar, or 1×10−3 bar 1 millibar =1 hectopascal. The word bar has its origin in the Greek word βάρος, the units official symbol is bar, the earlier symbol b is now deprecated and conflicts with the use of b denoting the unit barn, but it is still encountered, especially as mb to denote the millibar. Between 1793 and 1795, the bar was used for a unit of weight in an early version of the metric system. Atmospheric air pressure is given in millibars where standard sea level pressure is defined as 1013 mbar,101.3,1.013 bar. Despite the millibar not being an SI unit, meteorologists and weather reporters worldwide have long measured air pressure in millibars as the values are convenient, for example, the weather office of Environment Canada uses kilopascals and hectopascals on their weather maps. In contrast, Americans are familiar with the use of the millibar in US reports of hurricanes, in fresh water, there is an approximate numerical equivalence between the change in pressure in decibars and the change in depth from the water surface in metres. Specifically, an increase of 1 decibar occurs for every 1.019716 m increase in depth, in sea water with respect to the gravity variation, the latitude and the geopotential anomaly the pressure can be converted into meters depth according to an empirical formula. As a result, decibars are commonly used in oceanography, many engineers worldwide use the bar as a unit of pressure because, in much of their work, using pascals would involve using very large numbers. In the automotive field, turbocharger boost is often described in bars outside the USA), unicode has characters for mb and bar, but they exist only for compatibility with legacy Asian encodings and are not intended to be used in new documents. The kilobar, equivalent to 100 MPa, is used in geological systems. Bar and bara are sometimes used to indicate absolute pressures and bar and this usage is deprecated and fuller descriptions such as gauge pressure of 2 bar or 2 bar gauge are recommended.0 Unported License but not under the GFDL.

Pascal (unit)
–
The pascal is the SI derived unit of pressure used to quantify internal pressure, stress, Youngs modulus and ultimate tensile strength. It is defined as one newton per square meter and it is named after the French polymath Blaise Pascal. Common multiple units of the pascal are the hectopascal which is equal to one millibar, the unit of measurement called standard atmosphere is defined as 101,325 Pa and approximates to the average pressure at sea-level at the latitude 45° N. Meteorological reports typically state atmospheric pressure in hectopascals, the unit is named after Blaise Pascal, noted for his contributions to hydrodynamics and hydrostatics, and experiments with a barometer. The name pascal was adopted for the SI unit newton per square metre by the 14th General Conference on Weights, one pascal is the pressure exerted by a force of magnitude one newton perpendicularly upon an area of one square metre. The unit of measurement called atmosphere or standard atmosphere is 101325 Pa and this value is often used as a reference pressure and specified as such in some national and international standards, such as ISO2787, ISO2533 and ISO5024. In contrast, IUPAC recommends the use of 100 kPa as a standard pressure when reporting the properties of substances, geophysicists use the gigapascal in measuring or calculating tectonic stresses and pressures within the Earth. Medical elastography measures tissue stiffness non-invasively with ultrasound or magnetic resonance imaging, in materials science and engineering, the pascal measures the stiffness, tensile strength and compressive strength of materials. In engineering use, because the pascal represents a small quantity. The pascal is also equivalent to the SI unit of energy density and this applies not only to the thermodynamics of pressurised gases, but also to the energy density of electric, magnetic, and gravitational fields. In measurements of sound pressure, or loudness of sound, one pascal is equal to 94 decibels SPL, the quietest sound a human can hear, known as the threshold of hearing, is 0 dB SPL, or 20 µPa. The airtightness of buildings is measured at 50 Pa, the units of atmospheric pressure commonly used in meteorology were formerly the bar, which was close to the average air pressure on Earth, and the millibar. Since the introduction of SI units, meteorologists generally measure pressures in hectopascals unit, exceptions include Canada and Portugal, which use kilopascals. In many other fields of science, the SI is preferred, many countries also use the millibar or hectopascal to give aviation altimeter settings. In practically all fields, the kilopascal is used instead. Centimetre of water Metric prefix Orders of magnitude Pascals law

Atlantic hurricane
–
An Atlantic hurricane or tropical storm is a tropical cyclone that forms in the Atlantic Ocean, usually in the summer or fall. A hurricane differs from a cyclone or typhoon only on the basis of location, a hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean, a typhoon occurs in the northwestern Pacific Ocean, and a cyclone occurs in the south Pacific or Indian Ocean. Tropical cyclones can be categorized by intensity, Tropical storms have one-minute maximum sustained winds of at least 39 mph, while hurricanes have one-minute maximum sustained winds exceeding 74 mph. Most North Atlantic tropical storms and hurricanes form between June 1 and November 30, in recent times, tropical disturbances that reach tropical storm intensity are named from a predetermined list. On average, in the North Atlantic basin 11.3 named storms occur each season, the climatological peak of activity is around September 11 each season. In March 2004, Catarina was the first hurricane-intensity tropical cyclone recorded in the Southern Atlantic Ocean. Tropical cyclones are steered by the flow throughout the depth of the troposphere. Specifically, air flow around high pressure systems and toward low pressure areas influence hurricane tracks, south of the subtropical ridge, surface easterly winds prevail. If the subtropical ridge is weakened by a trough, a tropical cyclone may turn poleward and then recurve. Poleward of the ridge, westerly winds prevail and generally steer tropical cyclones that reach northern latitudes toward the east. The westerlies also steer extratropical cyclones with their cold and warm fronts from west to east, generally speaking, the intensity of a tropical cyclone is determined by either the storms maximum sustained winds or lowest barometric pressure. The following table lists the most intense Atlantic hurricanes in terms of their lowest barometric pressure, in terms of wind speed, Hurricane Allen was the strongest Atlantic tropical cyclone on record, with maximum sustained winds of 190 mph. However, these measurements are suspect since instrumentation used to document wind speeds at the time would likely succumb to winds of such intensity, nonetheless, their central pressures are low enough to rank them among the strongest recorded Atlantic hurricanes. Owing to their intensity, the strongest Atlantic hurricanes have all attained Category 5 classification, Hurricane Opal, the strongest Category 4 hurricane recorded, intensified to reach a minimum pressure of 916 mbar, a pressure typical of Category 5 hurricanes. Nonetheless, the pressure remains too high to list Opal as one of the ten strongest Atlantic tropical cyclones, however, this was later superseded by Hurricane Patricia in 2015 in the east Pacific, which had a pressure reading of 872 mbar. Preceding Wilma is Hurricane Gilbert, which had held the record for most intense Atlantic hurricane for 17 years. The 1935 Labor Day hurricane, with a pressure of 892 mbar, is the third strongest Atlantic hurricane, since the measurements taken during Wilma and Gilbert were documented using dropsonde, this pressure remains the lowest measured over land. However, with a pressure of 895 mbar, Rita is the strongest tropical cyclone ever recorded in the Gulf of Mexico

1920 Atlantic hurricane season
–
The 1920 Atlantic hurricane season featured tropical storms and hurricanes only in the month of September. Although no hurricane season was defined at the time, the delineation of such is June 1 to November 30. The first system, a hurricane, developed on September 7 while the last, of note, four of the six cyclones co-existed with another tropical cyclone during the season. Of the seasons six tropical cyclones, five tropical storms. Furthermore, none of these strengthened into a major hurricane—Category 3 or higher on the modern-day Saffir–Simpson hurricane wind scale—marking the seventh such occurrence since 1900, the strongest hurricane of the season peaked as only as a strong Category 2 with winds of 110 mph. The second hurricane caused one death and $1.45 million in damage in Louisiana, the left one fatality in North Carolina. The seasons activity was reflected with an accumulated cyclone energy rating of 30 and it is only calculated for full advisories on tropical systems at or exceeding 39 mph, which is tropical storm strength. The first known storm of the season was identified on September 7 as a 40 mph tropical storm over Atlantic Ocean. Traveling towards the northwest, the storm intensified, attaining hurricane-status late on September 9. The following day, a ship in the vicinity of the recorded a pressure of 985 mbar. Around 1200 UTC, the hurricane turned towards the north and intensified into a modern-day Category 2 hurricane on the Saffir-Simpson Hurricane Scale early on September 11, the storm continued to intensify through September 12 when it reached its peak intensity with winds of 110 mph. After maintaining this intensity for 18 hours, the hurricane began to weaken as it turned towards the northwest, by 0000 UTC on September 14, the storm weakened to a Category 1 hurricane. The system began to undergo a transition, completing the process early the next day. The system tracked nearly due east before dissipating on September 16 to the north of the Azores islands, an area of disturbed weather developed into a tropical depression northwest of Colombia on September 16. Afterwards, it weakened over land, before dissipating on September 23 over eastern Kansas. As it approached the United States Gulf Coast, the forced a estimated 4,500 people to evacuate off of Galveston Island. At landfall, the hurricane generated strong winds along a swath of the coast, uprooting trees and causing damage to homes. Heavy rainfall associated with the peaked at 11.9 in in Robertsdale

1921 Atlantic hurricane season
–
The 1921 Atlantic hurricane season ran through the summer and the first half of fall in 1921. The season was average, with six tropical cyclones forming during the season. A tropical storm formed in the western Caribbean before moving across the Yucatan peninsula into the southern Gulf of Mexico, the storm recurved towards the north, strengthening into a category 1 hurricane before it struck Sargent, Texas. During the night of June 21, winds increased to 68 miles per hour at Corpus Christi, a barge with 18,000 gallons of oil sank in Port Aransas, Texas. A storm surge of 7.1 feet was measured at Pass Cavallo, as the cyclone moved inland, it passed directly over Palacios, Texas, Wharton, Texas, and Wallis, Texas. Winds gusted to 60 miles per hour at both Galveston, Texas and Houston, Texas, heavy rains accompanied the system, with 10.10 inches recorded at Matagorda, Texas. A category 1 struck Tampico, Mexico in early September after moving northwest from the Gulf of Mexico, after it dissipated on September 8, an extremely heavy rainfall event ensued across central Texas, which continued into September 11. In Williamson County, Texas, a new 18-hour rainfall record was set for the United States as 36.40 inches was recorded at Thrall, the deluge led to one of the most destructive floods in the history of San Antonio, Texas. Water rose to 7 feet deep in the city, forcing people to evacuate vertically within taller buildings, the most significant river floods occurred on the Little and San Gabriel rivers, where 159 people perished. Combined with the toll from elsewhere across the region,215 people died due to this storm. A Cape Verde-type hurricane, Three formed about 500 miles east of the island of Trinidad and it moved westward and struck the Windward Islands as a Category 1 hurricane. It tracked northward as a Category 2 hurricane and after a short lull was upgraded back to a Category 3 hurricane and it became an extratropical cyclone well off the coast of Newfoundland and accelerated before dissipating about 100 miles off the southern tip of Greenland. A category 1 formed in the Atlantic and never approached land, another notable system was a tropical storm that made a transatlantic journey from off the coast of South Carolina to just southwest of the Azores. It was later determined that it was extratropical for most of the journey, the most notable storm of the season was the Tampa Bay hurricane of 1921. It developed in the southwestern Caribbean Sea on October 20 and it tracked north-northwestward, steadily strengthening into a hurricane on October 22. The storm turned more north-northeastward, and upon reaching the Gulf of Mexico on October 24 it rapidly intensified to a 140 mph Category 4 and it weakened as it continued to the northeast, making landfall north of Clearwater on October 25 as a Category 3 hurricane. It crossed Florida, turned eastward across the Atlantic, and became extratropical on October 28 southwest of Bermuda and its small and quick nature, as well as well-executed warnings, only caused $3 million in damage, with 6 casualties. Tropical Storm Seven formed on November 19 and it made landfall in Cuba before dissipating on November 25

1923 Atlantic hurricane season
–
The 1923 Atlantic hurricane season ran its course from Summer through Fall of 1923. The season was slightly below average with 9 tropical storms, of which 4 became hurricanes, on June 19 a weak tropical depression formed from the tail end of a dying cold front, north of Western Bahamas and east of Florida. The tropical depression moved north after its formation. Failing to intensify further it was absorbed by a cold front sweeping down the East Coast on June 22. The peak winds from this system were 25 knts from ship observations on June 19, the lowest pressure was 1012 millibars. Due to the nature of this system and lack of gale winds it was evaluated as a tropical depression and was not included in HURDAT. In 2009 this tropical depression was first detected from Historical Weather Maps when Landsea, early on June 22, a broad area of low pressure was observed in the Bay of Campeche where it intensified into a tropical depression later that day. It remained at that intensity for the three days while drifting slowly northeastward, while its pressure continued to gradually fall. By late June 25, it had begun to become better organized, the storm clipped the southeastern Louisiana and made landfall as a minimal tropical storm over extreme southern Mississippi and Alabama on June 26. Excessive rains fell in the vicinity of the cyclone and further up the East Coast of the United States, the system weakened into a tropical depression while over southeastern Alabama late on June 26. The cyclone turned in a easterly direction under the influence of an extratropical low. On June 27, it regained tropical storm intensity as it reached the Atlantic Ocean off the Georgia–South Carolina coast, on June 28, the cyclone reached a peak intensity of 60 mph and a peripheral pressure of 999 mbar. At this time, the low to the northwest began to affect this tropical storm more heavily. This storm was first introduced to HURDAT in a 2009 reanalysis of the basin, the season began late with a tropical storm observed northeast of Turks and Caicos on August 30. The cyclone turned north and then northeast, very close to Bermuda, after passing Bermuda and reaching hurricane strength, the storm turned north and slowed down. For two days, the storm drifted northward across the Atlantic, reaching a peak intensity of 105 mph. On September 8, the weakened to a Category 1 hurricane. The storm became extratropical shortly before striking Newfoundland, on the evening of September 9 and this tropical storm formed near the coast of Africa on September 7, however it was short lived and never approached land

1924 Atlantic hurricane season
–
The 1924 Atlantic hurricane season featured the earliest known Category 5 hurricane – a tropical cyclone with maximum sustained winds exceeding 155 mph. The first system, Tropical Storm One, was first detected in the northwestern Caribbean Sea on June 18, the final system, an unnumbered tropical depression, dissipated on November 24. These dates fall within the period with the most tropical activity in the Atlantic. Of the 13 tropical cyclones of the season, six existed simultaneously, the season was average with 11 tropical storms, three of which strengthened into hurricanes. Further, two of those three intensified into hurricanes, which are Category 3 or higher on the Saffir–Simpson hurricane wind scale. The most significant storm of the season was Hurricane Ten, nicknamed the 1924 Cuba hurricane and it struck western Cuba as a Category 5 hurricane, before weakening and making landfall in Florida as a Category 1 hurricane. Severe damage and 90 fatalities were reported at both locations. Another system, Hurricane Four, brought winds and flooding to the Leeward Islands. The storm left 59 deaths,30 of which were on Montserrat alone, several other tropical cyclones had minor impacts on land, including Tropical Storms One, Eight, and Ten, as well as Hurricanes Three and Five. Overall, the storms of the 1924 Atlantic hurricane season caused at least 150 fatalities. The seasons activity was reflected with a low accumulated cyclone energy rating of 100, ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots or tropical storm strength. A tropical storm was detected 75 miles southeast of Chetumal, Quintana Roo on June 18 and it made landfall on northern Belize with estimated winds near 45 mph. Pressures were progressively decreasing over the days in the northwestern Caribbean Sea. The tropical system crossed the Yucatán Peninsula, emerging over the Bay of Campeche on June 19 with 40 mph winds and it re-strengthened over water and re-attained winds of 45 mph. Early on June 21, the storm made landfall 115 miles south of Tampico, the cyclone was classified as a weak disturbance, and strong winds were not recorded throughout the life span of the storm. Squalls affected the Texas coast, prompting advisories for small watercraft, heavy rainfall was reported in Mexico. Toward the end of July, a cold front off the east coast of Florida resulted in the formation of a tropical storm. The storm tracked northeast, steadily intensifying to reach winds of 65 mph as it passed near the Outer Banks of North Carolina

Tropical cyclone
–
Depending on its location and strength, a tropical cyclone is referred to by names such as hurricane, typhoon /taɪˈfuːn/, tropical storm, cyclonic storm, tropical depression, and simply cyclone. A hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean, a typhoon occurs in the northwestern Pacific Ocean, Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water from the ocean surface and this energy source differs from that of mid-latitude cyclonic storms, such as noreasters and European windstorms, which are fueled primarily by horizontal temperature contrasts. The strong rotating winds of a tropical cyclone are a result of the conservation of momentum imparted by the Earths rotation as air flows inwards toward the axis of rotation. As a result, they form within 5° of the equator. Tropical cyclones are typically between 100 and 2,000 km in diameter, Tropical refers to the geographical origin of these systems, which form almost exclusively over tropical seas. Cyclone refers to their nature, with wind blowing counterclockwise in the Northern Hemisphere. The opposite direction of circulation is due to the Coriolis effect, in addition to strong winds and rain, tropical cyclones are capable of generating high waves, damaging storm surge, and tornadoes. They typically weaken rapidly over land where they are cut off from their energy source. For this reason, coastal regions are vulnerable to damage from a tropical cyclone as compared to inland regions. Heavy rains, however, can cause significant flooding inland, though their effects on human populations are often devastating, tropical cyclones can relieve drought conditions. They also carry heat away from the tropics and transport it toward temperate latitudes. Tropical cyclones are areas of low pressure in the troposphere. On Earth, the pressures recorded at the centers of tropical cyclones are among the lowest ever observed at sea level, the environment near the center of tropical cyclones is warmer than the surroundings at all altitudes, thus they are characterized as warm core systems. The near-surface wind field of a cyclone is characterized by air rotating rapidly around a center of circulation while also flowing radially inwards. At the outer edge of the storm, air may be nearly calm, however, due to the Earths rotation, as air flows radially inward, it begins to rotate cyclonically in order to conserve angular momentum. At an inner radius, air begins to ascend to the top of the troposphere and this radius is typically coincident with the inner radius of the eyewall, and has the strongest near-surface winds of the storm, consequently, it is known as the radius of maximum winds. Once aloft, air flows away from the center, producing a shield of cirrus clouds

Cape Verde
–
Located 570 kilometres off the coast of West Africa, the islands cover a combined area of slightly over 4,000 square kilometres. The Cape Verde archipelago was uninhabited until the 15th century, when Portuguese explorers discovered and colonized the islands, ideally located for the Atlantic slave trade, the islands grew prosperous throughout the 16th and 17th centuries, attracting merchants, privateers, and pirates. The end of slavery in the 19th century led to economic decline, Cape Verde gradually recovered as an important commercial center and stopover for shipping routes. Incorporated as a department of Portugal in 1951, the islands continued to agitate for independence. Since the early 1990s, Cape Verde has been a representative democracy. Lacking natural resources, its economy is mostly service-oriented, with a growing focus on tourism. Its population of around 512,000 is mostly of mixed European and sub-Saharan African heritage, a sizeable diaspora community exists across the world, slightly outnumbering inhabitants on the islands. Historically, the name Cape Verde has been used in English for the archipelago and, since independence in 1975, for the country. In 2013, the Cape Verdean government determined that the Portuguese designation Cabo Verde would henceforth be used for official purposes, such as at the United Nations, Cape Verde is a member of the African Union. The name of the stems from the nearby Cap-Vert, on the Senegalese coast. In 1444 Portuguese explorers had named that landmark as Cabo Verde, on 24 October 2013, the countrys delegation announced at the United Nations that the official name should no longer be translated into other languages. Instead of Cape Verde, the designation Republic of Cabo Verde is to be used, before the arrival of Europeans, the Cape Verde Islands were uninhabited. The islands of the Cape Verde archipelago were discovered by Genoese and Portuguese navigators around 1456, according to Portuguese official records, the first discoveries were made by Genoa-born António de Noli, who was afterwards appointed governor of Cape Verde by Portuguese King Afonso V. Other navigators mentioned as contributing to discoveries in the Cape Verde archipelago are Diogo Gomes, Diogo Dias, Diogo Afonso, in 1462, Portuguese settlers arrived at Santiago and founded a settlement they called Ribeira Grande. Ribeira Grande was the first permanent European settlement in the tropics, in the 16th century, the archipelago prospered from the Atlantic slave trade. Pirates occasionally attacked the Portuguese settlements, sir Francis Drake, an English corsair privateering under a letter of marque granted by the English crown, twice sacked the capital Ribeira Grande in 1585 when it was a part of the Iberian Union. After a French attack in 1712, the town declined in relative to nearby Praia. Decline in the trade in the 19th century resulted in an economic crisis

Leeward Islands
–
The Leeward Islands /ˈliːwərd/ are a group of islands in the West Indies. In English, the term refers to the islands of the Lesser Antilles chain. As a group they start east of Puerto Rico and reach southward to Dominica and they are situated where the northeastern Caribbean Sea meets the western Atlantic Ocean. The more southerly part of the Lesser Antilles chain are called the Windward Islands, the name of this island group, Leeward Islands, dates from previous centuries, when sailing ships were the sole form of transportation across the Atlantic Ocean. In the West Indies, the winds, known as the trade winds. The early Spanish colonizers called Puerto Rico and the islands to the west Sotavento, the islands to the south and east of Puerto Rico were then called Islas de Barlovento, meaning windward islands. When the British gained control of many of the Lesser Antilles, they designated Antigua, Montserrat, guadeloupe and the islands to the south were designated Windward Islands. Later on, all north of Martinique became known as the Leeward Islands. Thus, Dominica is the first of the Leeward islands, the islands along the Venezuelan coast, known in English as the Leeward Antilles, in languages other than English are known as the Leeward Islands. The islands are affected by volcanism, and notable eruptions have occurred in Montserrat in the 1990s. The islands were among the first parts of the Americas to fall under the control of the Spanish Empire, mont serrat in Catalan means saw mountain, referring to the serrated appearance of the mountain range. The Leeward Islands became a British colony in 1671, in 1699, prior to the War of the Spanish Succession, Christopher Codrington became the governor of the Leeward Islands. The war lasted from 1701 to 1714, daniel Parke II was the British governor of the Leeward Islands from 1706 to 1710. He was assassinated during a mutiny triggered by his self-enriching enforcement of Stuart imperialism, although comparatively much smaller than the surrounding islands in the Caribbean, the Leeward Islands posed the most significant rebellion to the British Stamp Act. In 1816 the colony was dissolved, with its last governor being James Leith, in 1833, the colony was reformed. From 1833 until 1871, the Governor of Antigua performed the duties of the Governor of the Leeward Islands, today the Islands are governed by a number of national and colonial administrations.

Bermuda
–
Bermuda is a British Overseas Territory in the North Atlantic Ocean. It is approximately 1,070 km east-southeast of Cape Hatteras, North Carolina,1,236 km south of Cape Sable Island, Nova Scotia, Bermuda is an associate member of Caribbean Community. The first person known to have reached Bermuda was the Spanish sea captain Juan de Bermúdez in 1503 and he claimed the islands for the Spanish Empire. Bermúdez never landed on the islands, but made two visits to the archipelago, of which he created a recognisable map, shipwrecked Portuguese mariners are now thought to have been responsible for the 1543 inscription on Portuguese Rock. Subsequent Spanish or other European parties are believed to have released pigs there, the island was administered as an extension of Virginia by the Company until 1614. Its spin-off, the Somers Isles Company, took over in 1615, at that time, the companys charter was revoked, and the English Crown took over administration. The islands became a British colony following the 1707 unification of the parliaments of Scotland and England, after 1949, when Newfoundland became part of Canada, Bermuda became the oldest remaining British Overseas Territory. Since the return of Hong Kong to China in 1997, it is the most populous Territory and its first capital, St. Georges, was established in 1612 and is the oldest continuously inhabited English town in the New World. Bermudas economy is based on insurance and reinsurance, and tourism. Bermuda had one of the worlds highest GDP per capita for most of the 20th century, recently, its economic status has been affected by the global recession. The island is in the belt and prone to severe weather. However, it is protected from the full force of a hurricane by the coral reef that surrounds the island. It is 898 nautical miles northeast of Miami, Florida, and 667 nautical miles from Cape Sable Island, in Nova Scotia, Canada. The islands lie due east of Fripp Island, South Carolina, west-northwest of Cape Verde, southeast of New York City, New York, north-northwest of Brazil and north of San Juan, Puerto Rico. The archipelago is formed by points on the rim of the caldera of a submarine volcano that forms a seamount. The volcano is one part of a range that was formed as part of the process that formed the floor of the Atlantic. It has 103 km of coastline, the two incorporated municipalities in Bermuda are the City of Hamilton and the Town of St George. Bermuda is divided into nine parishes, which have some localities called villages, such as Flatts Village, although usually referred to in the singular, the territory consists of 181 islands, with a total area of 53.3 square kilometres

Extratropical cyclone
–
Extratropical cyclones are capable of producing anything from cloudiness and mild showers to heavy gales, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as large scale low pressure systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, the term cyclone applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor extratropical signifies that this type of cyclone generally occurs outside the tropics and they are termed mid-latitude cyclones if they form within those latitudes, or post-tropical cyclones if a tropical cyclone has intruded into the mid latitudes. Weather forecasters and the public often describe them simply as depressions or lows. Terms like frontal cyclone, frontal depression, frontal low, extratropical low, non-tropical low, Extratropical cyclones are classified mainly as baroclinic, because they form along zones of temperature and dewpoint gradient known as frontal zones. They can become barotropic late in their cycle, when the distribution of heat around the cyclone becomes fairly uniform with its radius. Extratropical cyclones form anywhere within the regions of the Earth. A study of extratropical cyclones in the Southern Hemisphere shows that between the 30th and 70th parallels, there are an average of 37 cyclones in existence during any 6-hour period, a separate study in the Northern Hemisphere suggests that approximately 234 significant extratropical cyclones form each winter. Extratropical cyclones form along linear bands of temperature/dewpoint gradient with significant vertical wind shear, initially, cyclogenesis, or low pressure formation, occurs along frontal zones near a favorable quadrant of a maximum in the upper level jetstream known as a jet streak. The favorable quadrants are usually at the rear and left front quadrants. The divergence causes air to rush out from the top of the air column and this in turn forces convergence in the low-level wind field and increased upward motion within the column. The increased upward motion causes atmospheric pressure at ground level to lower and this is because the upward air motion counteracts gravity, lessening the weight of the atmosphere in that location. The lowered pressure strengthens the cyclone, as the cyclone strengthens, the cold front sweeps towards the equator and moves around the back of the cyclone. Meanwhile, its associated warm front progresses more slowly, as the air ahead of the system is denser. Later, the cyclones occlude as the portion of the cold front overtakes a section of the warm front, forcing a tongue, or trowal. Eventually, the cyclone will become cold and begin to weaken. Atmospheric pressure can fall very rapidly when there are upper level forces on the system

Cuba
–
Cuba, officially the Republic of Cuba, is a country comprising the island of Cuba as well as Isla de la Juventud and several minor archipelagos. Cuba is located in the northern Caribbean where the Caribbean Sea, the Gulf of Mexico, and it is south of both the U. S. state of Florida and the Bahamas, west of Haiti, and north of Jamaica. Havana is the largest city and capital, other cities include Santiago de Cuba. Cuba is the largest island in the Caribbean, with an area of 109,884 square kilometres, prior to Spanish colonization in the late 15th century, Cuba was inhabited by Amerindian tribes. It remained a colony of Spain until the Spanish–American War of 1898, as a fragile republic, Cuba attempted to strengthen its democratic system, but mounting political radicalization and social strife culminated in the dictatorship of Fulgencio Batista in 1952. Further unrest and instability led to Batistas ousting in January 1959 by the July 26 Movement, since 1965, the state has been governed by the Communist Party of Cuba. A point of contention during the Cold War between the Soviet Union and the United States, a nuclear war broke out during the Cuban Missile Crisis of 1962. Culturally, Cuba is considered part of Latin America, Cuba is a Marxist–Leninist one-party republic, where the role of the vanguard Communist Party is enshrined in the Constitution. Independent observers have accused the Cuban government of human rights abuses. It is one of the worlds last planned economies and its economy is dominated by the exports of sugar, tobacco, coffee, according to the Human Development Index, Cuba is described as a country with high human development and is ranked the eighth highest in North America. It also ranks highly in some metrics of national performance, including health care, the name Cuba comes from the Taíno language. The exact meaning of the name is unclear but it may be translated either as where fertile land is abundant, authors who believe that Christopher Columbus was Portuguese state that Cuba was named by Columbus for the town of Cuba in the district of Beja in Portugal. Before the arrival of the Spanish, Cuba was inhabited by three distinct tribes of indigenous peoples of the Americas, the Taíno, the Guanajatabey, and the Ciboney people. The ancestors of the Ciboney migrated from the mainland of South America, the Taíno arrived from Hispanola sometime in the 3rd century A. D. When Columbus arrived they were the dominant culture in Cuba, having a population of 150,000. The name Cuba comes from the native Taíno language and it is derived from either coabana meaning great place, or from cubao meaning where fertile land is abundant. The Taíno were farmers, while the Ciboney were farmers as well as fishers and hunter-gatherers, Columbus claimed the island for the new Kingdom of Spain and named it Isla Juana after Juan, Prince of Asturias. In 1511, the first Spanish settlement was founded by Diego Velázquez de Cuéllar at Baracoa, other towns soon followed, including San Cristobal de la Habana, founded in 1515, which later became the capital

Pensacola, Florida
–
Pensacola is the westernmost city in the Florida Panhandle and the county seat of Escambia County, in the U. S. state of Florida. As of the 2010 census, the city had a population of 51,923. Pensacola is the city of the Pensacola metropolitan area, which had an estimated 461,227 residents in 2012. Pensacola is a sea port on Pensacola Bay, which is protected by the island of Santa Rosa. The main campus of the University of West Florida is situated north of the city center, the area was originally inhabited by Muskogean peoples. The Pensacola people lived there at the time of European contact, Spanish explorer Tristán de Luna founded a short-lived settlement in 1559. In 1698 the Spanish established a presidio in the area, from which the city gradually developed. The area changed several times as European powers competed in North America. During Floridas British rule, fortifications were strengthened, other nicknames include Worlds Whitest Beaches, Cradle of Naval Aviation, Western Gate to the Sunshine State, Americas First Settlement, Emerald Coast, Red Snapper Capital of the World, and P-Cola. The original inhabitants of the Pensacola Bay area were Native American peoples, at the time of European contact, a Muskogean-speaking tribe known to the Spanish as the Pensacola lived in the region. This name was not recorded until 1677, but the tribe appears to be the source of the name Pensacola for the bay and thence the city. Creek people, also Muskogean-speaking, came regularly from present-day southern Alabama to trade, so the peoples were part of a broader regional and even continental network of relations. The best-known Pensacola culture site in terms of archeology is the Bottle Creek site and this site has at least 18 large earthwork mounds, five of which are arranged around a central plaza. Its main occupation was from 1250 AD to 1550 and it was a ceremonial center for the Pensacola people and a gateway to their society. This site would have had access by a dugout canoe. The areas written recorded history begins in the 16th century, with documentation by Spanish explorers who were the first Europeans to reach the area. The expeditions of Pánfilo de Narváez in 1528 and Hernando de Soto in 1539 both visited Pensacola Bay, the latter of which documented the name Bay of Ochuse. In 1559, Tristán de Luna y Arellano landed with some 1,500 people on 11 ships from Veracruz, Mexico

Bay of Campeche
–
The Bay of Campeche, or Campeche Sound, is a bight in the southern area of the Gulf of Mexico. It is surrounded on three sides by the Mexican states of Campeche, Tabasco and Veracruz, the area of the bay is 6,000 square miles and maximum depth of the bay is approximately 180 feet. It was named by Francisco Hernández de Córdoba and Antón de Alaminos during their expedition in 1517, the Cantarell Complex of five oil fields lies beneath the Bay of Campeche. In 2003 it was the second most productive oil field in the world, during the months of June and July, the Bay of Campeche is considered one of the hot breeding spots for Atlantic hurricanes. The bay is considered the eastern border on the main migration routes for birds in the Americas. Where do hurricanes form and where do they strike, archived from the original on 2005-11-20.

Nicaragua
–
Nicaragua, officially the Republic of Nicaragua, is the largest country in the Central American isthmus. Nicaraguas capital, Managua, is the countrys largest city and the third-largest city in Central America, the multi-ethnic population of six million includes indigenous peoples, Europeans, Africans, and Asians. Native tribes on the eastern coast speak their own languages, the Spanish Empire conquered the region in the 16th century. Nicaragua gained independence from Spain in 1821, since its independence, Nicaragua has undergone periods of political unrest, dictatorship, and fiscal crisis—the most notable causes that led to the Nicaraguan Revolution of the 1960s and 1970s. Nicaragua is a democratic republic. The biological diversity, warm climate and active volcanoes make Nicaragua an increasingly popular tourist destination. The name Nicaragua was coined by Spanish colonists based on the name Nicarao, when Spaniard Gil González Dávila came to Nicaragua in 1521 he found in the areas between Rivas and San Jorge the first pre-Columbian natives of Nicaragua. At the time the city was called Quauhcapolca and the cacique leaders name was Macuilmiquiztli. The Pipil migrated to Nicaragua from central Mexico after 500 BC, meanwhile, the Caribbean coast of Nicaragua was inhabited by other peoples, mostly Chibcha language groups. They had coalesced in Central America and migrated also to present-day northern Colombia and they lived a life based primarily on hunting and gathering. In 1502, Christopher Columbus became the first European known to have reached what is now Nicaragua as he sailed southeast toward the Isthmus of Panama, on his fourth voyage, Columbus explored the Miskito Coast on the Atlantic side of Nicaragua. The Spanish attempted to convert all three tribes to Christianity, Nicaragua and Nicarao and their people converted, but Dirangen, however, did not, the first attempt to conquer what is now known as Nicaragua was by Gil González Dávila, who arrived in Panama in January 1520. The first Spanish permanent settlements were founded in 1524, conquistador Francisco Hernández de Córdoba founded two of Nicaraguas principal towns in 1524, Granada on Lake Nicaragua was the first settlement, followed by León at a location west of Lake Managua. Córdoba soon built defenses for the cities and fought against incursions by other conquistadors, Córdoba was later publicly beheaded following a power struggle with Pedro Arias Dávila. His tomb and remains were discovered in 2000 in the ruins of León Viejo, the clashes among Spanish forces did not impede their destruction of the indigenous people and their culture. The series of battles came to be known as the War of the Captains, Pedro Arias Dávila was a winner, although he had lost control of Panama, he moved to Nicaragua and successfully established his base in León. Through adroit diplomatic machinations, he became the first governor of the colony, many indigenous people died as a result of new infectious diseases, compounded by neglect by the Spaniards, who controlled their subsistence. In 1610, the Momotombo volcano erupted, destroying the capital and it was rebuilt northwest of what is now known as the ruins of Old León

Swan Islands, Honduras
–
The islands are inhabited by a small permanent Honduran navy garrison, located at Great Swan Island. The Swan Islands lie within the economic zone of Honduras. The islands are uninhabited, except for a small Honduran navy garrison, Great Swan has an airstrip, Islas del Cisne Airport. At the turn of the century, Swan Island was set up as a U. S. Department of Agriculture animal quarantine station for the importation of beef, also, the United Fruit Co. set up a wireless radio relay station for servicing their Caribbean fleet. During World War II, both the U. S. Navy and the U. S. Weather Bureau stationed personnel on the island. Later, the Federal Aviation Agency and the National Weather Service set up meteorological and communications assets on Swan in support of aeronautical services, the FAA departed Swan Island in the 1960s, leaving the NWS all assets and responsibilities. Both the United States and Honduras claimed the Swan Islands until the United States dropped its claim under the Guano Islands Act in 1972, the ownership of the island has always been in dispute. The Sumner Smith family has maintained their ownership and, apparently. Still, the U. S. elected to abandon its claim, the islands gained attention in the early 1960s due to the activities of Radio Swan, that began broadcasting in May 1960 during preparation for, and during, the abortive Bay of Pigs Invasion of Cuba. The station was removed from the islands in the late 1960s, in 1965, a former Bellaire High School student was questioned by police over his role in a teenage army dedicated to freeing oppressed countries, the Houston Chronicle reported. The group, called the Kononiers, had been in existence for five years, the student told the paper. The weapons were taken to the Addicks Reservoir area, where they trained for combat, the youths were training for Operation Liberation Swan Island off Honduras.

Honduras
–
Honduras, officially the Republic of Honduras, is a republic in Central America. It has at times referred to as Spanish Honduras to differentiate it from British Honduras. Honduras was home to several important Mesoamerican cultures, most notably the Maya, the Spanish introduced Roman Catholicism and the now predominant Spanish language, along with numerous customs that have blended with the indigenous culture. Honduras has the worlds highest murder rate, Honduras spans about 112,492 km2 and has a population exceeding 8 million. Its northern portions are part of the Western Caribbean Zone, as reflected in the areas demographics and culture. Honduras is known for its natural resources, including minerals, coffee, tropical fruit, and sugar cane, as well as for its growing textiles industry. Honduras literally means depths in Spanish, the name could either refer to the bay of Trujillo as an anchorage, fondura in the Leonese dialect of Spanish, or to Columbuss alleged quote that Gracias a Dios que hemos salido de esas Honduras. It was not until the end of the 16th century that Honduras was used for the whole province, prior to 1580, Honduras only referred to the eastern part of the province, and Higueras referred to the western part. Another early name is Guaymuras, revived as the name for the dialogue in 2009 that took place in Honduras as opposed to Costa Rica. In pre-Columbian times, modern Honduras was part of the Mesoamerican cultural area, in the west, the Maya civilization flourished for hundreds of years. The dominant state within Hondurass borders was in Copán, Copán fell with the other Lowland centres during the conflagrations of the Terminal Classic in the 9th century. The Maya of this civilization survive in western Honduras as the Chorti, remains of other Pre-Columbian cultures are found throughout the country. On 30 July 1502 Columbus sent his brother Bartholomew to explore the islands and Bartholomew encountered a Mayan trading vessel from Yucatán, carrying well-dressed Maya and a rich cargo. Bartholomews men stole whatever cargo they wanted and kidnapped the elderly captain to serve as an interpreter in what was the first recorded encounter between the Spanish and the Maya. In March 1524, Gil González Dávila became the first Spaniard to enter Honduras as a conquistador, followed by Hernán Cortés, bringing forces down from Mexico. Much of the conquest was done in the two decades, first by groups loyal to Cristóbal de Olid, and then by those loyal of Francisco Montejo. In addition to Spanish resources, the conquerors relied heavily on armed forces from Mexico—Tlaxcalans, resistance to conquest was led in particular by Lempira, and many regions in the north never fell to the Spanish, notably the Miskito Kingdom. After the Spanish conquest, Honduras became part of Spains vast empire in the New World within the Kingdom of Guatemala, Trujillo and Gracias were the first city-capitals

Quintana Roo, officially the Free and Sovereign State of Quintana Roo, is one of the 31 states which, with the Federal District, make up the 32 federal entities of Mexico. It is divided into ten municipalities and its capital city is Chetumal and it is located in Southeastern Mexico, on the eastern part of the Yucatán Peninsula. Quintana Roo has a coastline to the east with the Caribbean Sea and it also claims territory which gives it a small border with Guatemala in the southwest of the state, although this disputed area is also claimed by Campeche. The Sian Kaan biosphere reserve is located in the state. The statewide population is expanding at a rapid rate due to the construction of hotels, many immigrants come from Yucatán, Campeche, Tabasco, and Veracruz. On February 1,2015, Quintana Roo officially adopted a new zone, Southeastern, which is five hours behind Coordinated Universal Time. Reasons cited for the change include coordination of air travel, banking operations, and more daylight hours, the area that makes up modern Quintana Roo was long part of Yucatán, sharing its history. With the Caste War of Yucatán, which started in the 1840s, the independent Maya nation of Chan Santa Cruz was based on what is now the town of Felipe Carrillo Puerto. For decades it maintained independence, having separate trade and treaty relationships with British Honduras. Quintana Roo was made a territory of Mexico by decree of President Porfirio Díaz on November 24,1902 and it was named after an early patriot of the Mexican Republic, Andrés Quintana Roo. The Mexican army succeeded in defeating most of the Maya population of the region during the 1910s, in 1915 the area was again declared to be legally part of the state of Yucatán. Quintana Roo was granted statehood within the United Mexican States on October 8,1974 and it is the Mexican Republics youngest state. According to the Köppen climate classification, much of the state has a tropical wet, the mean annual temperature is 26 °C. The hottest months are April and August where the high is 33 °C while January is coldest month with an average low of 17 °C. Extreme temperatures can range from low of 10 °C in the coldest months to 36 °C in the hottest months, Quintana Roo averages 1,300 mm of precipitation per year, which falls throughout the year, though June to October are the wetter months. Hurricanes can occasionally hit the areas during the hurricane season. The State of Quintana Roo is divided into 11 municipalities, each headed by a municipal president, Quintana Roo ranks sixth among Mexican states according to the United Nations Human Development index. The Yucatán Peninsula is one of the most forested areas of the world in terms of mass per hectare

Gulf of Mexico
–
The Gulf of Mexico is an ocean basin largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U. S. states of Alabama, Florida, Louisiana, Mississippi and Texas border the Gulf on the north, Atlantic and Pacific coasts, or sometimes the south coast, in juxtaposition to the Great Lakes region being the north coast. One of the seven main areas is the Gulf of Mexico basin. The Gulf of Mexico formed approximately 300 million years ago as a result of plate tectonics, the Gulfs basin is roughly oval and is approximately 810 nautical miles wide and floored by sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Florida Straits between the U. S. and Cuba, and with the Caribbean Sea via the Yucatan Channel between Mexico and Cuba, with the narrow connection to the Atlantic, the Gulf experiences very small tidal ranges. The size of the Gulf basin is approximately 1.6 million km2, almost half of the basin is shallow continental shelf waters. The basin contains a volume of roughly 2,500 quadrillion liters, the consensus among geologists who have studied the geology of the Gulf of Mexico, is that prior to the Late Triassic, the Gulf of Mexico did not exist. It was created by the collision of plates that formed Pangea. As interpreted by Roy Van Arsdale and Randel T. Cox, geologists and other Earth scientists agree in general that the present Gulf of Mexico basin originated in Late Triassic time as the result of rifting within Pangea. The rifting was associated with zones of weakness within Pangea, including sutures where the Laurentia, South American, first, there was a Late Triassic-Early Jurassic phase of rifting during which rift valleys formed and filled with continental red beds. Second, as rifting progressed through Early and Middle Jurassic time and it was at this time that tectonics first created a connection to the Pacific Ocean across central Mexico and later eastward to the Atlantic Ocean. This flooded the basin created by rifting and crustal thinning to create the Gulf of Mexico. While the Gulf of Mexico was a basin, the subsiding transitional crust was blanketed by the widespread deposition of Louann Salt. Initially, during the Late Jurassic, continued rifting widened the Gulf of Mexico and progressed to the point that sea-floor spreading, at this point, sufficient circulation with the Atlantic Ocean was established that the deposition of Louann Salt ceased. During the Late Jurassic through Early Cretaceous, the occupied by the Gulf of Mexico experienced a period of cooling. The subsidence was the result of a combination of stretching, cooling. Initially, the combination of stretching and cooling caused about 5–7 km of tectonic subsidence of the central thin transitional

Maximum sustained wind
–
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a distance defined as the radius of maximum wind, unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Surface winds are variable due to friction between the atmosphere and the Earths surface, as well as near hills and mountains over land. Over the ocean, satellite imagery determines the value of the sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, and radar imagery can also estimate this quantity and this value helps determine damage expected from a tropical cyclone, through use of such scales as the Saffir-Simpson scale. However, the United States National Weather Service defines sustained winds within tropical cyclones by averaging winds over a period of one minute, measured at the same 10 metres height. This is an important distinction, as the value of the highest one-minute sustained wind is about 14% greater than a sustained wind over the same period. In most tropical cyclone basins, use of the satellite-based Dvorak technique is the method used to determine a tropical cyclones maximum sustained winds. The extent of banding and difference in temperature between the eye and eyewall is used within the technique to assign a maximum sustained wind. Central pressure values for their centers of low pressure are approximate, the intensity of example hurricanes is derived from both the time of landfall and the maximum intensity. The tracking of individual clouds on minutely satellite imagery could be used in the future in estimating surface winds speeds for tropical cyclones, ship and land observations are also used, when available. Doppler weather radar can be used in the manner to determine surface winds with tropical cyclones near land. Friction between the atmosphere and the Earths surface causes a 20% reduction in the wind at the surface of the Earth, surface roughness also leads to significant variation of wind speeds. Over land, winds maximize at hill or mountain crests, while sheltering leads to wind speeds in valleys. Compared to over water, maximum sustained winds over land average 8% lower, in most basins, maximum sustained winds are used to define their category. In the Atlantic and northeast Pacific oceans, the Saffir-Simpson scale is used and this scale can be used to determine possible storm surge and damage impact on land. In most basins, the category of the cyclone is determined from the cyclones maximum sustained wind. Only in Australia is this quantity not used to define the tropical category, in their basin

Atmospheric pressure
–
Atmospheric pressure, sometimes also called barometric pressure, is the pressure exerted by the weight of air in the atmosphere of Earth. In most circumstances atmospheric pressure is approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so that atmospheric pressure decreases with increasing elevation. On average, a column of air one square centimetre in cross-section, measured from sea level to the top of the atmosphere, has a mass of about 1.03 kilograms and that force is a pressure of 10.1 N/cm2 or 101 kN/m2. A column 1 square inch in cross-section would have a weight of about 14.7 lb or about 65.4 N and it is modified by the planetary rotation and local effects such as wind velocity, density variations due to temperature and variations in composition. The standard atmosphere is a unit of pressure defined as 101325 Pa, the mean sea level pressure is the average atmospheric pressure at sea level. This is the pressure normally given in weather reports on radio, television. When barometers in the home are set to match the weather reports, they measure pressure adjusted to sea level. The altimeter setting in aviation, is an atmospheric pressure adjustment, average sea-level pressure is 1013.25 mbar. In aviation weather reports, QNH is transmitted around the world in millibars or hectopascals, except in the United States, Canada, however, in Canadas public weather reports, sea level pressure is instead reported in kilopascals. The highest sea-level pressure on Earth occurs in Siberia, where the Siberian High often attains a sea-level pressure above 1050 mbar, the lowest measurable sea-level pressure is found at the centers of tropical cyclones and tornadoes, with a record low of 870 mbar. Pressure varies smoothly from the Earths surface to the top of the mesosphere, although the pressure changes with the weather, NASA has averaged the conditions for all parts of the earth year-round. As altitude increases, atmospheric pressure decreases, one can calculate the atmospheric pressure at a given altitude. Temperature and humidity affect the atmospheric pressure, and it is necessary to know these to compute an accurate figure. The graph at right was developed for a temperature of 15 °C, at low altitudes above the sea level, the pressure decreases by about 1.2 kPa for every 100 meters. See pressure system for the effects of air pressure variations on weather, Atmospheric pressure shows a diurnal or semidiurnal cycle caused by global atmospheric tides. This effect is strongest in tropical zones, with an amplitude of a few millibars and these variations have two superimposed cycles, a circadian cycle and semi-circadian cycle. The highest adjusted-to-sea level barometric pressure recorded on Earth was 1085.7 hPa measured in Tosontsengel

Tamaulipas
–
Tamaulipas, officially the Free and Sovereign State of Tamaulipas, is one of the 31 states which, with Mexico City, comprise the 32 Federal Entities of Mexico. It is divided into 43 municipalities and its capital city is Ciudad Victoria, the capital city was named after Guadalupe Victoria, the first President of Mexico. It is located in Northeastern Mexico and it is bordered by the states of Veracruz to the southeast, San Luis Potosí to the southwest and Nuevo León to the west. To the north, it has a 370 km stretch of the U. S. –Mexico border along the state of Texas and this state is known to be both a territorial struggle for the Gulf Cartel and the Los Zetas. The name Tamaulipas is derived from Tamaholipa, a Huastec term in which the tam- prefix signifies place, there is no scholarly agreement on the meaning of holipa, but high hills is a common interpretation. Another explanation of the name is that it is derived from Ta ma holipam. In addition to the city, Ciudad Victoria, the states largest cities include Reynosa, Matamoros, Nuevo Laredo. The area known as Tamaulipas has been inhabited for at least 8,000 years, several different cultures have come and gone during that period. Tamaulipas was originally populated by the Olmec people and later by Chichimec and Huastec tribes, between 1445 and 1466, Mexica armies commanded by Moctezuma I Ilhuicamina conquered much of the territory and transformed it into a tributary region for the Mexica empire. However, the Aztecs never fully conquered certain mostly nomadic indigenous groups in the area, although Hernán Cortés conquered the Aztecs rather quickly, it took a gradual process for Spain to subjugate the inhabitants of Tamaulipas in the 16th and 17th centuries. The first permanent Spanish settlement in the area was Tampico in 1554, further settlement was done by Franciscan missionaries, widespread cattle and sheep ranching by the Spanish bolstered the area’s economy while forcing native populations from their original lands. Repeated indigenous rebellions kept the area unstable and weakened colonial interest in the region, what is now Tamaulipas was first incorporated as a separate province of New Spain in 1746 with the name Nuevo Santander. The local government capital during this time moved from Santander to San Carlos, the territory of this time spanned from the San Antonio river to the north east to the Gulf of Mexico, then south to the Panuco River near Tampico and west to the Sierra Madre Mountains. The area became a haven for rebellious Indians who fled there after increased Spanish settlements in Nuevo León, one of these groups was known as Lipan. By 1790 Europeans turned their attention from the groups and focused on containing the Apache invaders. In northeastern Coahuila and adjacent Texas, Spanish and Apache displacements created an ethnic mix. Here the local Indians mixed with displaced groups from Coahuila and Chihuahua, some groups, to escape the pressure, combined and migrated north into the Central Texas highlands. In 1824, after the Mexican War of Independence from Spain, during the fights between centralists and federalists that soon followed, the successful Texas Revolution led to the creation of the Republic of Texas in 1836

Rio Grande
–
The Rio Grande is one of the principal rivers in the southwest United States and northern Mexico. The Rio Grande begins in south-central Colorado in the United States, along the way, it forms part of the Mexico–United States border. According to the International Boundary and Water Commission, its length was 1,896 miles in the late 1980s. Depending on how it is measured, the Rio Grande is the fourth- or fifth-longest river system in North America. The river serves as part of the border between the U. S. state of Texas and the Mexican states of Chihuahua, Coahuila, Nuevo León. A very short stretch of the river serves as part of the boundary between the U. S. states of Texas and New Mexico. Since the mid–20th century, heavy consumption of farms and cities along with many large diversion dams on the river has left only 20% of its natural discharge to flow to the Gulf. Near the rivers mouth, the heavily irrigated lower Rio Grande Valley is an important agricultural region, the Rio Grande is one of 19 Great Waters recognized by Americas Great Waters Coalition. The Rio Grandes watershed covers 182,200 square miles, many endorheic basins are situated within, or adjacent to, the Rio Grandes basin, and these are sometimes included in the river basins total area, increasing its size to about 336,000 square miles. The Rio Grande rises in the part of the Rio Grande National Forest in the U. S. state of Colorado. The river is formed by the joining of several streams at the base of Canby Mountain in the San Juan Mountains and it then continues on a southerly route through the desert cities of Albuquerque, and Las Cruces to El Paso, Texas and Ciudad Juárez, Chihuahua. In the Albuquerque area, the river flows past a number of historic Pueblo villages, including Sandia Pueblo, below El Paso, it serves as part of the border between the United States and Mexico. The official river border measurement ranges from 889 miles to 1,248 miles, a major tributary, the Rio Conchos, enters at Ojinaga, Chihuahua, below El Paso, and supplies most of the water in the border segment. Other well-known tributaries include the Pecos and the smaller Devils, which join the Rio Grande on the site of Amistad Dam. Despite its name and length, the Rio Grande is not navigable by ocean-going ships, in New Mexico, the river flows through the Rio Grande rift from one sediment-filled basin to another, cutting canyons between the basins and supporting a fragile bosque ecosystem on its flood plain. From El Paso eastward, the flows through desert. Although irrigated agriculture exists throughout most of its stretch, it is extensive in the subtropical Lower Rio Grande Valley. The river ends in a small, sandy delta at the Gulf of Mexico, during portions of 2001 and 2002, the mouth of the Rio Grande was blocked by a sandbar

Texas
–
Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America. Three of its borders are defined by rivers, the Rio Grande forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south

Eagle Pass, Texas
–
Eagle Pass is a city in and the county seat of Maverick County in the US state of Texas. The population was 26,255 as of the 2010 census Eagle Pass borders the city of Piedras Negras, Coahuila, Mexico, the Eagle Pass-Piedras Negras Metropolitan Area is one of six binational metropolitan areas along the United States-Mexican border. As of January 2008, according to the US census, the Eagle Pass Metropolitan Areas population was 48,401 people, Eagle Pass was the first American settlement on the Rio Grande. Originally known as Camp Eagle Pass, it served as a temporary outpost for the Texas militia, Eagle pass is so named because the contour of the hills through which the Rio Grande flows bore a fancied resemblance to the outstretched wings of an eagle. General William Leslie Cazneau founded the Eagle Pass townsite in the 1840s, in 1850, Rick Pawless opened a trading post called Eagle Pass. In 1871, Maverick County was established, and Eagle Pass was named the county seat, during the remainder of the 19th century, schools and churches opened, the mercantile and ranching industries grew, and a railway was built. The United States Army established the presumably permanent Fort Duncan on March 27,1849, captain Sidney Burbank supervised the construction of Fort Duncan, which was named after Colonel James Duncan, who had fought in the Mexican War. After the Mexican-American War, trade flourished under the protection of the fort, the fort was near the trail of westward immigration to California. It also served as an outpost against hostile Apache and it was abandoned and reopened several times. In March 1860, it served as the base of operations against the border assaults arranged by Juan N. Cortina, Fort Duncan was held by the Confederacy during the American Civil War. After several decades of deactivation, Fort Duncan was activated as a camp during World War I. In 1938, the City of Eagle Pass acquired the fort and still operates a museum, the rancher and gunfighter King Fisher lived in Eagle Pass until his ambush and murder in San Antonio in 1884. During World War I Camp Eagle Pass was established as a post of the U. S. Army, the 3rd Infantry Regiment was assigned there and patrolled the Mexican Border. The City of Eagle Pass was sued by the US government in 2008 to gain access to the land, Eagle Pass and Maverick County have been the subject of several state and federal criminal investigations which have gained state and national media attention. He was also ordered to pay a maximum of $56,003.88 in restitution to Maverick County, in some instances, defendants charged individuals a reduced rate for fuel purchased using the city’s credit card and then pocketed the cash. Chavez admitted to having given false information in 2015, still free on bond pending sentencing, Chavez could receive up to five years imprisonment. The city and surrounding area is home to a variety of businesses in retail, import, food manufacturing, the Eagle Pass Industrial Park hosts a number of larger companies including the O. F.

Windward Islands
–
The Windward Islands are the southern, generally larger islands of the Lesser Antilles, within the West Indies. They lie south of the Leeward Islands, between latitudes 12° and 16° N and longitudes 60° and 62° W in one definition, as a group they start from Dominica and reach southward to the North of Trinidad & Tobago. The trans-Atlantic currents and winds that provided the fastest route across the ocean brought these ships to the dividing line between the Windward and Leeward islands. Dominica is the line between the Windward and Leeward islands. Guadeloupe and the islands to the south were designated Windward Islands, later on, all islands north of Martinique became known as the Leeward Islands. The chain of Windward Islands forms a part of the easternmost boundary of the Caribbean Sea, most of the present Windward Islands were once colonial island territories of France, also known as the French Antilles

Storm surge
–
Most casualties during tropical cyclones occur as the result of storm surges. The deadliest storm surge on record was the 1970 Bhola cyclone, the low-lying coast of the Bay of Bengal is particularly vulnerable to surges caused by tropical cyclones. The deadliest storm surge in the twenty-first century was caused by the Cyclone Nargis, the next deadliest in this century was caused by the Typhoon Haiyan, which killed more than 6,000 people in the central Philippines in 2013 and resulted in economic losses estimated at $14 billion. Louis, Diamondhead and Pass Christian in Mississippi, a high storm surge occurred in New York City from Hurricane Sandy in October 2012, with a high tide of 14 ft. The pressure effects of a tropical cyclone will cause the level in the open ocean to rise in regions of low atmospheric pressure. The rising water level will counteract the low pressure such that the total pressure at some plane beneath the water surface remains constant. This effect is estimated at a 10 mm increase in sea level for every millibar drop in atmospheric pressure, strong surface winds cause surface currents at a 45° angle to the wind direction, by an effect known as the Ekman Spiral. Wind stresses cause a phenomenon referred to as wind set-up, which is the tendency for water levels to increase at the downwind shore, intuitively, this is caused by the storm simply blowing the water towards one side of the basin in the direction of its winds. Because the Ekman Spiral effects spread vertically through the water, the effect is proportional to depth. The pressure effect and the wind set-up on an open coast will be driven into bays in the way as the astronomical tide. The Earths rotation causes the Coriolis effect, which bends currents to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. When this bend brings the currents into more contact with the shore it can amplify the surge. The effect of waves, while powered by the wind, is distinct from a storms wind-powered currents. Powerful wind whips up large, strong waves in the direction of its movement, although these surface waves are responsible for very little water transport in open water, they may be responsible for significant transport near the shore. When waves are breaking on a more or less parallel to the beach. The rainfall effect is experienced predominantly in estuaries, Hurricanes may dump as much as 12 in of rainfall in 24 hours over large areas, and higher rainfall densities in localized areas. As a result, watersheds can quickly surge water into the rivers that drain them and this can increase the water level near the head of tidal estuaries as storm-driven waters surging in from the ocean meet rainfall flowing from the estuary. This situation well exemplified by the southeast coast of Florida

1899 San Ciriaco hurricane
–
1899 San Ciriaco hurricane, also known as the 1899 Puerto Rico Hurricane, was the longest-lived Atlantic hurricane on record. The third tropical cyclone and first major hurricane of the season and it slowly strengthened while heading steadily west-northwestward across the Atlantic Ocean and reached hurricane status by late on August 5. During the following 48 hours, it deepened further, reaching Category 4 on the modern day Saffir–Simpson hurricane wind scale before crossing the Leeward Islands on August 7, later that day, the storm peaked winds of 150 mph. The storm weakened slightly before making landfall in Guayama, Puerto Rico with winds of 140 mph on August 8, several hours later, it emerged into the southwestern Atlantic as a Category 3 hurricane. The system paralleled the north coast of Dominican Republic and then crossed the Bahamas, thereafter, it began heading northward on August 14, while centered east of Florida. Early on the day, the storm re-curved northeastward and appeared to be heading out to sea. However, by August 17, it turned back to the northwest and made landfall near Hatteras, no stronger hurricane has made landfall on the Outer Banks since San Ciriaco. The storm weakened after moving inland and fell to Category 1 intensity by 1200 UTC on August 18, later that day, the storm re-emerged into the Atlantic. Now heading northeastward, it continued weakening, but maintained Category 1 intensity, by late on August 20, the storm curved eastward over the northwestern Atlantic. It also began losing tropical characteristics and transitioned into a cyclone at 0000 UTC on August 22. However, after four days, the system regenerated into a storm while located about 695 miles west-southwest of Flores Island in the Azores on August 26. It moved slowly north-northwestward, until curving to the east on August 29, between August 26 and September 1, the storm did not differentiate in intensity, but began re-strengthening while turning southeastward on September 2. Early on the day, the storm again reached hurricane intensity. It curved northeastward and passed through the Azores on September 3, in Guadeloupe, the storm unroofed and flooded many houses. Communications were significantly disrupted in the portions of the island. Impact was severe in Montserrat, with every building destroyed and 100 deaths reported. About 200 small houses were destroyed on Saint Kitts, with estates suffering considerable damage, eleven deaths were reported on the island. In Puerto Rico, the system brought winds and heavy rainfall

Florida /ˈflɒrᵻdə/ is a state located in the southeastern region of the United States. It is bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, Florida is the 22nd-most extensive, the 3rd-most populous, and the 8th-most densely populated of the U. S. states. Jacksonville is the most populous municipality in the state and is the largest city by area in the contiguous United States, the Miami metropolitan area is Floridas most populous urban area. The city of Tallahassee is the state capital, much of the state is at or near sea level and is characterized by sedimentary soil. The climate varies from subtropical in the north to tropical in the south, the American alligator, American crocodile, Florida panther, and manatee can be found in the Everglades National Park. It was a location of the Seminole Wars against the Native Americans. Today, Florida is distinctive for its large Cuban expatriate community and high population growth, the states economy relies mainly on tourism, agriculture, and transportation, which developed in the late 19th century. Florida is also renowned for amusement parks, orange crops, the Kennedy Space Center, Florida has attracted many writers such as Marjorie Kinnan Rawlings, Ernest Hemingway and Tennessee Williams, and continues to attract celebrities and athletes. It is internationally known for golf, tennis, auto racing, by the 16th century, the earliest time for which there is a historical record, major Native American groups included the Apalachee, the Timucua, the Ais, the Tocobaga, the Calusa and the Tequesta. Florida was the first part of the continental United States to be visited and settled by Europeans, the earliest known European explorers came with the Spanish conquistador Juan Ponce de León. Ponce de León spotted and landed on the peninsula on April 2,1513 and he named the region La Florida. The story that he was searching for the Fountain of Youth is a myth, in May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land. He described seeing a wall of red mangroves spread mile after mile, some reaching as high as 70 feet. Very soon, many smokes appeared along the whole coast, billowing against the sky, the Spanish introduced Christianity, cattle, horses, sheep, the Spanish language, and more to Florida. Both the Spanish and French established settlements in Florida, with varying degrees of success, in 1559, Don Tristán de Luna y Arellano established a settlement at present-day Pensacola, making it the first attempted settlement in Florida, but it was abandoned by 1561. Spain maintained tenuous control over the region by converting the tribes to Christianity. The area of Spanish Florida diminished with the establishment of English settlements to the north, the English attacked St. Augustine, burning the city and its cathedral to the ground several times. Florida attracted numerous Africans and African-Americans from adjacent British colonies who sought freedom from slavery, in 1738, Governor Manuel de Montiano established Fort Gracia Real de Santa Teresa de Mose near St

Fujiwhara effect
–
The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, extratropical cyclones typically engage in binary interaction when within 2,000 kilometres of one another, while tropical cyclones typically interact within 1,400 kilometres of each other. When cyclones are in proximity of one another, their centers will begin orbiting cyclonically about a point between the two due to their cyclonic wind circulations. The two vortices will be attracted to other, and eventually spiral into the center point. It has not been agreed upon whether this is due to the divergent portion of the wind or vorticity advection, when the two vortices are of unequal size, the larger vortex will tend to dominate the interaction, and the smaller vortex will orbit around it. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described it in a 1921 paper about the motion of vortices in water, Tropical cyclones can form when smaller circulations within the Intertropical Convergence Zone merge. The effect is often mentioned in relation to the motion of tropical cyclones, the effect becomes noticeable when they approach within 1,400 kilometres of each other. Rotation rates within binary pairs accelerate when tropical cyclones close within 650 kilometres of each other, merger of the two systems becomes realized when they are within 300 kilometres of one another. Hurricane Iris of the 1995 Atlantic hurricane season interacted with Hurricane Humberto, in 2005, the remnant low of Tropical Depression Thirteen moved northward and then northeastward around a non-tropical low located to the north of the system. It briefly strengthened into Tropical Storm Lee, thereafter, Lee weakened back to a tropical depression as it moved northeastward and northwestward around the eastern side of the non-tropical low and eventually absorbed the non-tropical low. In the same year, Alpha was absorbed by Wilma, in 1974, Hurricanes Kirsten and Ione interacted in a Fujiwara interaction, as Ione was pulled north east, while Kirsten was pulled to the north west. In the same year, Francesca and Gretchen interacted with each other, in 2001, Gil absorbed Henriette but associated convection totally dissipated during the merger and did not return afterwards. In 2005, Lidia was absorbed by Max, in 2014, Hurricane Karina initially moved west, but was steered back east by an interaction with Hurricane Lowell, where it was absorbed by Hurricane Marie. In September 1994, Typhoon Pat and Tropical Storm Ruth completed an orbit around their centroid before collapsing into a single cyclone. In August 1997, Tropical Storm Yule merged with Tropical Depression 16W, in October 2009, Typhoon Parma interacted with Typhoon Melor, affecting the movement of Parma. Parma was moving through the South China Sea but made a move to southeastward, so it made its second. In addition, due to the interaction with Melor, Parma weakened into a storm by October 4. In November 2009, Typhoon Nida absorbed Tropical Depression 27W and become a powerful typhoon, in August 2010, a Fujiwara interaction occurred between Tropical Storm Namtheun and Severe Tropical Storm Lionrock

Massachusetts
–
It is bordered by the Atlantic Ocean to the east, the states of Connecticut and Rhode Island to the south, New Hampshire and Vermont to the north, and New York to the west. The state is named for the Massachusett tribe, which inhabited the area. The capital of Massachusetts and the most populous city in New England is Boston, over 80% of Massachusetts population lives in the Greater Boston metropolitan area, a region influential upon American history, academia, and industry. Originally dependent on agriculture, fishing and trade, Massachusetts was transformed into a manufacturing center during the Industrial Revolution, during the 20th century, Massachusetts economy shifted from manufacturing to services. Modern Massachusetts is a leader in biotechnology, engineering, higher education, finance. Plymouth was the site of the first colony in New England, founded in 1620 by the Pilgrims, in 1692, the town of Salem and surrounding areas experienced one of Americas most infamous cases of mass hysteria, the Salem witch trials. In 1777, General Henry Knox founded the Springfield Armory, which during the Industrial Revolution catalyzed numerous important technological advances, in 1786, Shays Rebellion, a populist revolt led by disaffected American Revolutionary War veterans, influenced the United States Constitutional Convention. In the 18th century, the Protestant First Great Awakening, which swept the Atlantic World, in the late 18th century, Boston became known as the Cradle of Liberty for the agitation there that led to the American Revolution. The entire Commonwealth of Massachusetts has played a commercial and cultural role in the history of the United States. Before the American Civil War, Massachusetts was a center for the abolitionist, temperance, in the late 19th century, the sports of basketball and volleyball were invented in the western Massachusetts cities of Springfield and Holyoke, respectively. Many prominent American political dynasties have hailed from the state, including the Adams, both Harvard University and the Massachusetts Institute of Technology, also in Cambridge, have been ranked among the most highly regarded academic institutions in the world. Massachusetts public school students place among the top nations in the world in academic performance, the official name of the state is the Commonwealth of Massachusetts. While this designation is part of the official name, it has no practical implications. Massachusetts has the position and powers within the United States as other states. Massachusetts was originally inhabited by tribes of the Algonquian language family such as the Wampanoag, Narragansett, Nipmuc, Pocomtuc, Mahican, and Massachusett. While cultivation of crops like squash and corn supplemented their diets, villages consisted of lodges called wigwams as well as longhouses, and tribes were led by male or female elders known as sachems. Between 1617 and 1619, smallpox killed approximately 90% of the Massachusetts Bay Native Americans, the first English settlers in Massachusetts, the Pilgrims, arrived via the Mayflower at Plymouth in 1620, and developed friendly relations with the native Wampanoag people. This was the second successful permanent English colony in the part of North America that later became the United States, the event known as the First Thanksgiving was celebrated by the Pilgrims after their first harvest in the New World which lasted for three days

North Carolina is a state in the southeastern region of the United States. The state borders South Carolina and Georgia to the south, Tennessee to the west, Virginia to the north, North Carolina is the 28th most extensive and the 9th most populous of the U. S. states. The state is divided into 100 counties, the most populous municipality is Charlotte, which is the second largest banking center in the United States after New York City. The state has a range of elevations, from sea level on the coast to 6,684 feet at Mount Mitchell. The climate of the plains is strongly influenced by the Atlantic Ocean. Most of the falls in the humid subtropical climate zone. More than 300 miles from the coast, the western, mountainous part of the state has a highland climate. North Carolina is bordered by South Carolina on the south, Georgia on the southwest, Tennessee on the west, Virginia on the north, the United States Census Bureau places North Carolina in the South Atlantic division of the southern region. So many ships have been lost off Cape Hatteras that the area is known as the Graveyard of the Atlantic, the most famous of these is the Queen Annes Revenge, which went aground in Beaufort Inlet in 1718. The coastal plain transitions to the Piedmont region along the Atlantic Seaboard fall line, the Piedmont region of central North Carolina is the states most populous region, containing the six largest cities in the state by population. It consists of rolling countryside frequently broken by hills or low mountain ridges. The Piedmont ranges from about 300 feet in elevation in the east to about 1,500 feet in the west, the western section of the state is part of the Appalachian Mountain range. Among the subranges of the Appalachians located in the state are the Great Smoky Mountains, Blue Ridge Mountains, the Black Mountains are the highest in the eastern United States, and culminate in Mount Mitchell at 6,684 feet, the highest point east of the Mississippi River. North Carolina has 17 major river basins, the five basins west of the Blue Ridge Mountains flow to the Gulf of Mexico, while the remainder flow to the Atlantic Ocean. Of the 17 basins,11 originate within the state of North Carolina, but only four are contained entirely within the states border – the Cape Fear, the Neuse, the White Oak, and the Tar-Pamlico basin. Elevation above sea level is most responsible for temperature change across the state, the climate is also influenced by the Atlantic Ocean and the Gulf Stream, especially in the coastal plain. These influences tend to cause warmer winter temperatures along the coast, the coastal plain averages around 1 inch of snow or ice annually, and in many years, there may be no snow or ice at all. North Carolina experiences severe weather in summer and winter, with summer bringing threat of hurricanes, tropical storms, heavy rain

New Jersey
–
New Jersey is a state in the Northeastern and mid-Atlantic regions of the United States. It is bordered on the north and east by New York, on the southeast and south by the Atlantic Ocean, on the west by Pennsylvania, New Jersey is the fourth-smallest state but the 11th-most populous and the most densely populated of the 50 United States. New Jersey lies entirely within the statistical areas of New York City. New Jersey was inhabited by Native Americans for more than 2,800 years, in the early 17th century, the Dutch and the Swedes made the first European settlements. New Jersey was the site of decisive battles during the American Revolutionary War in the 18th century. In the 19th century, factories in cities such as Camden, Paterson, Newark, Trenton, around 180 million years ago, during the Jurassic Period, New Jersey bordered North Africa. The pressure of the collision between North America and Africa gave rise to the Appalachian Mountains, around 18,000 years ago, the Ice Age resulted in glaciers that reached New Jersey. As the glaciers retreated, they left behind Lake Passaic, as well as rivers, swamps. New Jersey was originally settled by Native Americans, with the Lenni-Lenape being dominant at the time of contact, scheyichbi is the Lenape name for the land that is now New Jersey. The Lenape society was divided into clans that were based upon common female ancestors. These clans were organized into three distinct phratries identified by their animal sign, Turtle, Turkey, and Wolf and they first encountered the Dutch in the early 17th century, and their primary relationship with the Europeans was through fur trade. The Dutch became the first Europeans to lay claim to lands in New Jersey, the Dutch colony of New Netherland consisted of parts of modern Middle Atlantic states. Although the European principle of ownership was not recognized by the Lenape. The first to do so was Michiel Pauw who established a patronship called Pavonia in 1630 along the North River which eventually became the Bergen, peter Minuits purchase of lands along the Delaware River established the colony of New Sweden. During the English Civil War, the Channel Island of Jersey remained loyal to the British Crown and it was from the Royal Square in St. Helier that Charles II of England was proclaimed King in 1649, following the execution of his father, Charles I. The North American lands were divided by Charles II, who gave his brother, the Duke of York, the region between New England and Maryland as a proprietary colony. James then granted the land between the Hudson River and the Delaware River to two friends who had remained loyal through the English Civil War, Sir George Carteret and Lord Berkeley of Stratton, the area was named the Province of New Jersey. Since the states inception, New Jersey has been characterized by ethnic, New England Congregationalists settled alongside Scots Presbyterians and Dutch Reformed migrants

Low-pressure area
–
A low-pressure area, low, or depression is a region where the atmospheric pressure is lower than that of surrounding locations. Low-pressure systems form under areas of wind divergence that occur in the levels of the troposphere. The formation process of an area is known as cyclogenesis. Within the field of meteorology, atmospheric divergence aloft occurs in two areas, the first area is on the east side of upper troughs, which form half of a Rossby wave within the Westerlies. A second area of wind divergence aloft occurs ahead of embedded shortwave troughs, diverging winds aloft ahead of these troughs cause atmospheric lift within the troposphere below, which lowers surface pressures as upward motion partially counteracts the force of gravity. Thermal lows form due to localized heating caused by greater sunshine over deserts, since localized areas of warm air are less dense than their surroundings, this warmer air rises, which lowers atmospheric pressure near that portion of the Earths surface. Large-scale thermal lows over continents help drive monsoon circulations, low-pressure areas can also form due to organized thunderstorm activity over warm water. When this occurs over the tropics in concert with the Intertropical Convergence Zone, Monsoon troughs reach their northerly extent in August and their southerly extent in February. When a convective low acquires a well-hot circulation in the tropics it is termed a tropical cyclone, Tropical cyclones can form during any month of the year globally, but can occur in either the northern or southern hemisphere during November. Since clouds reflect sunlight, incoming solar radiation decreases, which causes lower temperatures during the day. At night the effect of clouds on outgoing longwave radiation, such as heat energy from the surface. The stronger the area of low pressure, the stronger the winds experienced in its vicinity, globally, low-pressure systems are most frequently located over the Tibetan Plateau and in the lee of the Rocky mountains. In Europe, recurring low-pressure weather systems are known as depressions. Cyclogenesis is the development and strengthening of cyclonic circulations, or low-pressure areas, cyclogenesis is the opposite of cyclolysis, and has an anticyclonic equivalent which deals with the formation of high-pressure areas—anticyclogenesis. Cyclogenesis is a term for several different processes, all of which result in the development of some sort of cyclone. Meteorologists use the term cyclone where circular pressure systems flow in the direction of the Earths rotation, the largest low-pressure systems are cold-core polar cyclones and extratropical cyclones which lie on the synoptic scale. Warm-core cyclones such as cyclones, mesocyclones, and polar lows lie within the smaller mesoscale. Subtropical cyclones are of intermediate size, cyclogenesis can occur at various scales, from the microscale to the synoptic scale

Kingston, Jamaica
–
Kingston is the capital and largest city of Jamaica, located on the southeastern coast of the island. It faces a natural harbour protected by the Palisadoes, a sand spit which connects the town of Port Royal. In the Americas, Kingston is the largest predominantly English-speaking city south of the United States. The local government bodies of the parishes of Kingston and St. Andrew were amalgamated by the Kingston and St. Andrew Corporation Act of 1923, to form the Kingston and St. Andrew Corporation. Greater Kingston, or the Corporate Area refers to areas under the KSAC, however, it does not solely refer to Kingston Parish. Kingston Parish had a population of 96,052, and St. Andrew parish had a population of 555,828 in 2001, Kingston is only bordered by Saint Andrew to the east, west and north. The city proper is bounded by Six Miles to the west, Stony Hill to the north, Papine to the northeast and Harbour View to the east, communities in urban and suburban Saint Andrew. Communities in rural St. Andrew such as Gordon Town, Mavis Bank, Lawrence Tavern, Mt. Airy, two parts make up the central area of Kingston, the historic Downtown, and New Kingston. Both are served by Norman Manley International Airport and also by the smaller, Kingston was founded in July 1692 as a place for survivors of the 1692 earthquake that destroyed Port Royal. Before the earthquake, Kingston’s functions were purely agricultural, the earthquake survivors set up a camp on the sea front. Approximately two thousand people died due to mosquito-borne diseases, initially the people lived in a tented camp on Colonel Barrys Hog Crawle. The town did not begin to grow until after the destruction of Port Royal by fire in 1703. Surveyor John Goffe drew up a plan for the town based on a grid bounded by North, East, West, by 1716 it had become the largest town and the centre of trade for Jamaica. The government sold land to people with the regulation that they no more than the amount of the land that they owned in Port Royal. Gradually wealthy merchants began to move their residences from above their businesses to the lands north on the plains of Liguanea.
