Peninsula Library System

The Peninsula Library System is a consortium of public and community college libraries in San Mateo County, United States, which serves the part of the San Francisco Bay Area known as "The Peninsula". The system has dozens of branches in local communities and at various area community colleges, a bookmobile, automated book kiosks called Library-a-Go-Go; the Peninsula Library System's mission states that it "strengthens local libraries through cooperation, enabling them to provide better service to their diverse communities." Peninsula Library System is a consortium of libraries, whose members are the branches of the San Mateo County Libraries, individual city libraries and their branches, area community college libraries. There are two branches in Burlingame: One main library, one at Easton; the PLS includes the libraries at Cañada College, College of San Mateo, Skyline College. There are four branches in Daly City: The John D. Daly branch on Hillside, the Bayshore branch, the Serramonte branch, the Westlake branch.

Menlo Park has both a branch at Belle Haven. Redwood City, Fair Oaks, Redwood Shores, Schaberg make up the four branches in the community of Redwood City. San Mateo has a main downtown location plus two minor branches, while South San Francisco has two a self-titled branches, both a main branch and one on Grand Avenue. Pacifica has two branches at Sharp Park; the remaining cities—San Bruno, Belmont, East Palo Alto, Foster City, Half Moon Bay, San Carlos and Portola Valley—have one location each.

Fort Worth Museum of Science and History

The Fort Worth Museum of Science and History is located on 1600 Gendy Street, Fort Worth, Texas 76107 in the city's Cultural District. It was opened in 1945 as the Fort Worth Children's Museum and moved to its current location in 1954. In 1968, the museum adopted its current name. Attractions at the museum include the Noble Planetarium and the Omni Theater, with Star's Cafe and Shop Too! Gift shop, in addition to both traveling and permanent science and history exhibits. In the fall of 2007, the museum was closed for renovations. During construction the museum had a limited presence in the National Cowgirl Museum and Hall of Fame next door, with a temporary "2 museums, 1 roof" campaign; the entire museum was moved into a new building at the same site in 2009. The new building was designed by architects Legorreta + Legorreta with Gideon Toal and consists of 166,000 square feet; the original Omni Theater and lobby were refurbished but left intact. In addition, the museum left one tree from the original museum courtyard undisturbed and built the museum around it, leaving the tree in an open area called the Heritage Courtyard.

The total maximum occupancy is 3,369 individuals. The museum's opening after renovations was on Friday, November 20, 2009. Designed for children 8 and under. Full articulations of dinosaur skeletons and a dig site replicating a local paleontological field site where children can play. A "museum within a museum," the Cattle Raisers Museum is a 10,000-square-foot exhibition dedicated to preserving and celebrating the vital history of the cattle industry. Regional energy and alternative energy resources. Innovation Studios are located off the Museum’s central corridor; these five glass-walled studios – which surround Innovation Gallery – are called "Inventor," "Doodler," "Designer," "Imaginer," and "Explorer." They are 6,000 square feet of engaging learning spaces. "150 Years of Fort Worth" traced Fort Worth's development, from its beginning as a frontier outpost, through its youth as a cattle town, to present day. Created by the Fort Worth Museum of Science and History, in cooperation with City Center Development Co. the exhibit was housed in the historic Fire Station No.

1, built in 1907. Fire Station No. 1 is located in the City Center complex at the northeast corner of Second and Commerce streets. This exhibit closed on February 19, 2016; the 90-seat Noble Planetarium features an exhibit area that provides large screens with views of the Sun, as well as downlinks offering information from the Hubble Telescope. Since its opening on April 19, 1983, the Omni has earned a reputation as an engaging learning environments. More than 10 million guests have journeyed to remote islands of the Pacific, explored deep under the ocean surface, splashed down the mighty Colorado of the Grand Canyon, stampeded across the vast Serengeti, traveled through the galaxy to the craters of Mars, inched up the treacherous peaks of Mount Everest without leaving their Omni seats! With an eight-story domed screen and 30-degree stadium seating, the Omni Theater is the largest IMAX dome in the United States west of the Mississippi River; the Omni’s 120-foot-wide screen places the audience in the center of the action.

The theater embodies a revolutionary concept in film presentation, which combines the drama of oversized film, state-of-the-art projection equipment, innovative tilt-domed theater architecture and the most sophisticated production techniques to create unique cinematic experiences.

Tropical cyclone track forecasting

Tropical cyclone track forecasting involves predicting where a tropical cyclone is going to track over the next five days, every 6 to 12 hours. The history of tropical cyclone track forecasting has evolved from a single-station approach to a comprehensive approach which uses a variety of meteorological tools and methods to make predictions; the weather of a particular location can show signs of the approaching tropical cyclone, such as increasing swell, increasing cloudiness, falling barometric pressure, increasing tides and heavy rainfall. The forces that affect tropical cyclone steering are the higher-latitude westerlies, the subtropical ridge, the beta effect caused by changes of the coriolis force within fluids such as the atmosphere. Accurate track predictions depend on determining the position and strength of high- and low-pressure areas, predicting how those areas will migrate during the life of a tropical system. Computer forecast models are used to help determine this motion as far out as five to seven days in the future.

The methods through which tropical cyclones are forecast have changed with the passage of time. The first known forecasts in the Western Hemisphere were made by Lt. Col. William Reed of the Corps of Royal Engineers at Barbados in 1847. Reed utilized barometric pressure measurements as the basis of his forecasts. Benito Viñes, S. J. introduced a warning system based on cloud cover changes in Havana during the 1870s. Forecasting hurricane motion was based on tide movements, as well as cloud and barometer changes over time. In 1895, it was noted that cool conditions with unusually high pressure preceded tropical cyclones in the West Indies by several days. Before the early 1900s, most forecasts were done by direct observations at weather stations, which were relayed to forecast centers via telegraph, it was not until the advent of radio in the early twentieth century that observations from ships at sea were available to forecasters. Despite the issuance of hurricane watches and warnings for systems threatening the coast, forecasting the path of tropical cyclones did not occur until 1920.

By 1922, it was known that the winds at 3 kilometres to 4 kilometres in height above the sea surface within the storms' right front quadrant were representative of a storm's steering, that hurricanes tended to follow the outermost closed isobar of the subtropical ridge. In 1937, radiosondes were used to aide tropical cyclone forecasting; the next decade saw the advent of aircraft-based reconnaissance by the military, starting with the first dedicated flight into a hurricane in 1943, the establishment of the Hurricane Hunters in 1944. In the 1950s, coastal weather radars began to be used in the United States, research reconnaissance flights by the precursor of the Hurricane Research Division began in 1954; the launch of the first weather satellite, TIROS-I, in 1960, introduced new techniques to tropical cyclone forecasting that remain important to the present day. In the 1970s, buoys were introduced to improve the resolution of surface measurements, which until that point, were not available at all over sea surfaces.

About four days in advance of a typical tropical cyclone, an ocean of 1 metre in height will roll in about every 10 seconds, moving towards the coast from the direction of the tropical cyclone's location. The ocean swell will increase in height and frequency the closer a tropical cyclone gets to land. Two days in advance of the center's passage, winds go calm as the tropical cyclone interrupts the environmental wind flow. Within 36 hours of the center passage, the pressure begins to fall and a veil of white cirrus clouds approaches from the cyclone's direction. Within 24 hours of the closest approach to the center, low clouds begin to move in known as the bar of a tropical cyclone, as the barometric pressure begins to fall more and the winds begin to increase. Within 18 hours of the center's approach, squally weather is common, with sudden increases in wind accompanied by rain showers or thunderstorms. Winds increase within 12 hours of the center's approach reaching hurricane force; the ocean's surface becomes whipped with foam.

Small items begin flying in the wind. Within 6 hours of the center's arrival, rain becomes continuous and the storm surge begins to come inland. Within an hour of the center, the rain becomes heavy and the highest winds within the tropical cyclone are experienced; when the center arrives with a strong tropical cyclone, weather conditions improve and the sun becomes visible as the eye moves overhead. At this point, the pressure ceases to drop as the lowest pressure within the storm's center is reached; this is when the peak depth of the storm surge occurs. Once the system departs, winds reverse and, along with the rain increase; the storm surge retreats as the pressure rises in the wake of its center. One day after the center's passage, the low overcast is replaced with a higher overcast, the rain becomes intermittent. By 36 hours after the center's passage, the high overcast breaks and the pressure begins to level off; the large scale synoptic scale flow determines 70 to 90 percent of a tropical cyclone's motion.

The deep-layered mean flow through the troposphere is considered to be the best tool in determining track direction and speed. If storms experience significant vertical wind shear, use of a lower level wind such as the 700 hPa pressure level will work out as a better predictor. Knowledge of the beta effect can be used to steer a tropical cyclone, since it leads to a more northwest heading for tropical cyclones in the Northern Hemisphere due to differences in the coriolis force around the cyclone
