Argentina
–
Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. With a mainland area of 2,780,400 km2, Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into provinces and one autonomous city, Buenos Aires. The provinces and the capital have their own constitutions, but exist under a federal system, Argentina claims sovereignty over part of Antarctica, the Falkland Islands, and South Georgia and the South Sandwich Islands. The earliest recorded presence in the area of modern-day Argentina dates back to the Paleolithic period. The country has its roots in Spanish colonization of the region during the 16th century, Argentina rose as the successor state of the Viceroyalty of the Río de la Plata, a Spanish overseas viceroyalty founded in 1776. The country thereafter enjoyed relative peace and stability, with waves of European immigration radically reshaping its cultural. The almost-unparalleled increase in prosperity led to Argentina becoming the seventh wealthiest developed nation in the world by the early 20th century, Argentina retains its historic status as a middle power in international affairs, and is a prominent regional power in the Southern Cone and Latin America. Argentina has the second largest economy in South America, the third-largest in Latin America and is a member of the G-15 and it is the country with the second highest Human Development Index in Latin America with a rating of very high. Because of its stability, market size and growing high-tech sector, the description of the country by the word Argentina has to be found on a Venice map in 1536. In English the name Argentina probably comes from the Spanish language, however the naming itself is not Spanish, Argentina means in Italian of silver, silver coloured, probably borrowed from the Old French adjective argentine of silver > silver coloured already mentioned in the 12th century. The French word argentine is the form of argentin and derives of argent silver with the suffix -in. The Italian naming Argentina for the country implies Argentina Terra land of silver or Argentina costa coast of silver, in Italian, the adjective or the proper noun is often used in an autonomous way as a substantive and replaces it and it is said lArgentina. The name Argentina was probably first given by the Venitian and Genoese navigators, in Spanish and Portuguese, the words for silver are respectively plata and prata and of silver is said plateado and prateado. Argentina was first associated with the silver mountains legend, widespread among the first European explorers of the La Plata Basin. The first written use of the name in Spanish can be traced to La Argentina, a 1602 poem by Martín del Barco Centenera describing the region, the 1826 constitution included the first use of the name Argentine Republic in legal documents. The name Argentine Confederation was also used and was formalized in the Argentine Constitution of 1853. In 1860 a presidential decree settled the name as Argentine Republic

Salta Province
–
Salta is a province of Argentina, located in the northwest of the country. Neighboring provinces are from the east clockwise Formosa, Chaco, Santiago del Estero, Tucumán, to the north it borders Bolivia and Paraguay and to the west lies Chile. The Atacamas lived in the Puna, and the Wichís, in the Chaco region, the first conquistador to venture into the area was Diego de Almagro in 1535, he was followed by Diego de Rojas. Hernando de Lerma founded San Felipe de Lerma in 1582, following orders of the viceroy Francisco de Toledo, Count of Oropesa, by 1650, the city had around five hundred inhabitants. An intendency of Salta del Tucumán was created within the Viceroyalty of the Río de la Plata, in 1774, San Ramón de La Nueva Orán was founded between Salta and Tarija. In 1783, in recognition of the importance of the city. The battle of Salta in 1813 freed the territory from Spain, gervasio de Posadas created the Province of Salta in 1814, containing the current provinces of Salta, Jujuy, and parts of southern Bolivia and northern Chile. Exploiting internal Argentine conflicts that arose after the Argentine Declaration of Independence, in 1834, Jujuy withdrew from Salta and became a separate province. The borders of Salta were further reduced in 1900, with the loss of Yacuiba to Bolivia. The National Government of Los Andes, constituted from the province in 1902 with a capital at San Antonio de los Cobres, was returned to Salta Province in 1943 as the Department of Los Andes. Antonio Alices painting, La muerte de Güemes, which received a Gold Medal at the Centenary Exposition, is on display at the offices of the Salta Provincial Government. The province is located in the zone and has a warm climate in general. The orientation of the Andes influences the distribution of precipitation within the province, the easternmost parts of the province have a semi-arid climate with a dry winter season. The mean annual temperature and precipitation are 20 °C and 500 millimetres, temperatures can reach up to 47 °C during summers, while they can fall down to −5 °C during winters. The first slopes of the Andes force the moist, easterly winds to rise, provoking very high condensation leading to the formation of clouds that generate copious amounts of rain. The eastern slopes of the mountains receive between 1,000 to 1,500 mm of precipitation a year, although some places receive up to 2,500 mm of precipitation annually owing to orographic precipitation. Most of the precipitation is concentrated in the summer, with winters being dry, the high rainfall on these first slopes creates a thick jungle that extends in a narrow strip along these ranges, creating an area of great species diversity. At higher altitudes on these slopes, the climate is cooler and more humid, with the vegetation consisting of deciduous, between the high altitudes to the east and the low plains to the west lie the valleys

Adobe
–
Adobe is a building material made from earth and often organic material. Adobe is among the earliest building materials, and is used throughout the world, modern methods of construction allow the pouring of whole adobe walls that are reinforced with steel. In dry climates, adobe structures are extremely durable, and account for some of the oldest existing buildings in the world. Adobe buildings offer significant advantages due to their greater thermal mass, cases where adobe structures were widely damaged during earthquakes include the 1976 Guatemala earthquake, the 2003 Bam earthquake and the 2010 Chile earthquake. Puebloan peoples built their structures with handfuls or basketfuls of adobe. Adobe bricks were used in Spain from the Late Bronze and Iron Ages and its wide use can be attributed to its simplicity of design and manufacture, and economics. A distinction is made between the smaller adobes, which are about the size of ordinary baked bricks, and the larger adobines. The word adobe /əˈdoʊbiː/ has existed for around 4000 years with little change in either pronunciation or meaning. The word can be traced from the Middle Egyptian word ɟbt mudbrick, Middle Egyptian evolved into Late Egyptian, Demotic or pre-Coptic, and finally to Coptic, where it appeared as τωωβε tōʾpə. This was borrowed into Arabic as الطوب aṭ-ṭawbu or aṭ-ṭūbu, with the definite article al- attached, tuba, English borrowed the word from Spanish in the early 18th century. In more modern English usage, the adobe has come to include a style of architecture popular in the desert climates of North America. An adobe brick is a material made of earth mixed with water. The soil composition typically contains sand, silt and clay, straw is useful in binding the brick together and allowing the brick to dry evenly, thereby preventing cracking due to uneven shrinkage rates through the brick. The most desirable soil texture for producing the mud of adobe is 15% clay, 10–30% silt, another source quotes 15–25% clay and the remainder sand and coarser particles up to cobbles 50 to 250 mm with no deleterious effect. Modern adobe is stabilized with either emulsified asphalt or Portland cement up to 10% by weight, no more than half the clay content should be expansive clays with the remainder non-expansive illite or kaolinite. Too much expansive clay results in uneven drying through the resulting in cracking. Typically the soils of the Southwest United States, where construction is in use, are an adequate composition. Adobe walls are bearing, i. e. they carry their own weight into the foundation rather than by another structure

Precipitation
–
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, graupel, Precipitation occurs when a portion of the atmosphere becomes saturated with water vapor, so that the water condenses and precipitates. Thus, fog and mist are not precipitation but suspensions, because the vapor does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated, Precipitation forms as smaller droplets coalesce via collision with other rain drops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers, moisture that is lifted or otherwise forced to rise over a layer of sub-freezing air at the surface may be condensed into clouds and rain. This process is active when freezing rain is occurring. A stationary front is often present near the area of freezing rain, provided necessary and sufficient atmospheric moisture content, the moisture within the rising air will condense into clouds, namely stratus and cumulonimbus. Eventually, the droplets will grow large enough to form raindrops. Lake-effect snowfall can be locally heavy, thundersnow is possible within a cyclones comma head and within lake effect precipitation bands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation, on the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. The movement of the trough, or intertropical convergence zone. Precipitation is a component of the water cycle, and is responsible for depositing the fresh water on the planet. Approximately 505,000 cubic kilometres of water falls as precipitation each year,398,000 cubic kilometres of it over the oceans and 107,000 cubic kilometres over land. Given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres, Climate classification systems such as the Köppen climate classification system use average annual rainfall to help differentiate between differing climate regimes. Precipitation may occur on celestial bodies, e. g. when it gets cold, Mars has precipitation which most likely takes the form of frost. Precipitation is a component of the water cycle, and is responsible for depositing most of the fresh water on the planet. Approximately 505,000 km3 of water falls as precipitation each year,398,000 km3 of it over the oceans, given the Earths surface area, that means the globally averaged annual precipitation is 990 millimetres. Mechanisms of producing precipitation include convective, stratiform, and orographic rainfall, Precipitation can be divided into three categories, based on whether it falls as liquid water, liquid water that freezes on contact with the surface, or ice

Cafayate
–
Cafayate is a town located at the central zone of the Valles Calchaquíes in the province of Salta, Argentina. It sits 1,683 metres above sea level, at a distance of 189 kilometres from Salta City and 1,329 kilometres from Buenos Aires. The town is an important tourist centre for exploring the Calchaquíes valleys, the largest golf course in South America, at 240 acres, is currently being developed just outside the city center at La Estancia de Cafayate. The town was founded in 1840 by Manuel Fernando de Aramburu, in 1863 the Cafayate Department was created, of which Cafayate is the capital. The Cafayates were a tribe of the Diaguita-Calchaquí group, which, together with the related Tolombón and their language was known as Cacán. Like other Diaguita tribes, they had fallen under the influence of the Incas. They later mounted a resistance to the Spaniards. Even though most agree that the root of Cafayate is Quechua, some claim it to mean Box of Water, others to be a deformation of Capac-Yac or Capac-Yaco. Another Cacán version understands it as Grave of Sorrows, the wine production is most important in the Valles Calchaquíes. The wines produced in the benefit from the low-humidity mild weather of the valleys that receive an average of less than 250 mm of precipitation per year. The most characteristic type of wine cultivated in the area is torrontés, most wine-cellars around the town host free guided tours. Many of the most impressive sights in the Valley of the Río las Conchas are along the paved, National Route 40 goes for 165 kilometres from Cafayate to Cachi, another of the most visited points in the area. Other points of interest from Cafayate include Molinos, Tolombón and San Isidro ranch, the town of Cafayate is an attraction by itself, with its laid-back rhythm, colonial style, and wine cellars open to the public.

Desert climate
–
An area that features this climate usually experiences from 25 to 200 mm per year of precipitation and in some years may experience no precipitation at all. Averages may be even less such as in Arica, Chile, there are usually two or three variations of a desert climate, a hot desert climate, a cold desert climate and, sometimes, a mild desert climate. To determine whether a location has a climate, the precipitation threshold is determined. If the areas precipitation is less than half the threshold. Hot desert climates are found under the subtropical ridge where there is largely unbroken sunshine for the whole year due to the stable descending air. These areas are located between 30 degrees south and 30 degrees north latitude, under the subtropical latitudes called the horse latitudes, hot desert climates are generally hot, sunny and dry year-round. Hot desert climates also reach similar latitudes in the Middle East, North Africa, hot desert climates usually feature hot, sometimes exceptionally hot, periods of the year. In many locations featuring a hot climate, maximum temperatures of over 40 °C are not uncommon in summer. The world absolute heat records, over 50 °C, are generally in the hot deserts, some desert locations consistently experience very high temperatures all year long, even during wintertime. These locations feature some of the highest annual average temperatures recorded on Earth and this last feature is seen in some parts of deserts of Africa and Arabia. During colder periods of the year, night-time temperatures can drop to freezing or below due to the radiation loss under the clear skies. However, very rarely do temperatures drop far below freezing, only one region in Europe has a hot desert climate, Province of Almeria, Province of Alicante and Province of Murcia in South Eastern Spain. Cold desert climates usually feature warm and dry summers, though summers typically are not quite as hot as summers in hot desert climates, unlike hot desert climates, cold desert climates tend to feature cold winters with rare snow. Cold desert climates are found at higher altitudes than hot desert climates. A cold desert climate is found in temperate zones, usually in the rain shadow of high mountains. A classic example of this is the Patagonian Desert in Argentina bounded by the Andes to its west, in the case of Central Asia, mountains restrict precipitation from the monsoon. The Gobi desert in Mongolia is an example of this. Though hot in summer, it shares the cold winters of the rest of Central Asia

Echinopsis atacamensis
–
Echinopsis atacamensis is a species of cactus from Chile, Argentina and Bolivia. The wood of this species can be used in building and in making furniture, Echinopsis atacamensis has a tall columnar habit, sometimes forming branches and becoming treelike. It grows to about 10 m high, with stems to 70 cm across, the stems have 20-30 ribs and areoles with 50-100 maroon coloured spines, the longest up to 30 cm long. The rose-white flowers are 10–14 cm long, borne on the sides of the stems, the dark green fruits are densely covered with hairs, up to 5 cm long, they are edible. Echinopsis atacamensis was first described by Rodolfo Philippi as Cereus atacamensis in 1860 and it was placed in a number of genera, including Trichocereus and Helianthocereus, before being moved to Echinopsis by Helmo Friedrich and Gordon Rowley in 1974. Subspecies pasacana is often branched, and occurs in Argentina and Bolivia, subspecies atacamensis is usually unbranched, less tall, and is found in Chile

Relative humidity
–
Relative humidity is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest and it requires less water vapor to attain high relative humidity at low temperatures, more water vapour is required to attain high relative humidity in warm or hot air. Humans are sensitive to high humidity because the body uses evaporative cooling, enabled by perspiration. Perspiration evaporates from the more slowly under humid conditions than under arid. For example, if the air temperature is 24 °C and the humidity is zero percent. If the relative humidity is 100 percent at the air temperature. In other words, if the air is 24 °C and contains saturated water vapor, then the human body cools itself at the rate as it would if it were 27 °C. The heat index and the humidex are indices that reflect the effect of temperature. In cold climates, the temperature causes lower capacity for water vapour to flow about. Dry cracked skin can result from dry air, low humidity causes tissue lining nasal passages to dry, crack and become more susceptible to penetration of Rhinovirus cold viruses. Low humidity is a cause of nosebleeds. The use of a humidifier in homes, especially bedrooms, can help with these symptoms, indoor relative humidities should be kept above 30% to reduce the likelihood of the occupants nasal passages drying out. Humans can be comfortable within a range of humidities depending on the temperature—from thirty to seventy percent—but ideally between 50% and 60%. Very low humidity can create discomfort, respiratory problems, and aggravate allergies in some individuals, in the winter, it is advisable to maintain relative humidity at 30 percent or above. Extremely low relative humidities may also cause eye irritation, wooden furniture can shrink, causing the paint that covers these surfaces to fracture. When the temperature is low and the humidity is high. When relative humidity approaches 100 percent, condensation can occur on surfaces, leading to problems with mold, corrosion, decay, condensation can pose a safety risk as it can promote the growth of mold and wood rot as well as possibly freezing emergency exits shut. The basic principles for buildings, above, also apply to vehicles, in addition, there may be safety considerations
