Hurricane Francelia (1969)
Hurricane Francelia was the deadliest hurricane of the 1969 Atlantic hurricane season after causing significant flooding to Central America, especially Belize and Guatemala. The sixth named storm and fourth hurricane of the season, Francelia developed from a tropical wave in the southeastern Caribbean Sea on August 29. It moved west-northwestward and strengthened into a tropical storm on the following day. On September 1, Francelia reached hurricane status, shortly before re-curving west-southwest. While approaching Central America, the storm intensified and peaked as a 100 mph (155 km/h) Category 2 hurricane on September 2. Francelia weakened slightly before making landfall near Punta Gorda, Belize (then British Honduras) late on September 3. The storm quickly weakened inland and dissipated by the following day. During its early stages, Francelia brought gusty winds and light rainfall to several islands in the Caribbean Sea. While remainin ...

Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...

National Hurricane Center
The National Hurricane Center (NHC) is the division of the United States' NOAA/National Weather Service responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean. The agency, which is co-located with the Miami branch of the National Weather Service, is situated on the campus of Florida International University in Westchester, Florida. The NHC's Tropical Analysis and Forecast Branch (TAFB) routinely issues marine forecasts, in the form of graphics and high seas forecasts year round, with the Ocean Prediction Center having backup responsibility for this unit. The Technology and Science Branch (TSB) provides technical support for the center, which includes new infusions of technology from abroad. The Chief, Aerial Reconnaissance Coordination, All Hurricanes (CARCAH) unit tasks planes, for r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Cayman
Grand Cayman is the largest of the three Cayman Islands and the location of the territory's capital, George Town. In relation to the other two Cayman Islands, it is approximately 75 miles (121 km) southwest of Little Cayman and 90 miles (145 km) southwest of Cayman Brac. Geography Grand Cayman encompasses 76% of the territory's entire land mass. The island is approximately long with its widest point being wide. The elevation ranges from sea level at the beaches to above sea level on the North Side's Mastic Trail. Unlike many other Caribbean islands, Grand Cayman is for the most part, flat. This allows for more space to build as the island’s population grows. Island districts Grand Cayman Island includes five of the six districts of the Cayman Islands: Bodden Town, East End, George Town, North Side and West Bay. *Bodden Town – Founded in the 1700s, Bodden Town district comprises the central part of Grand Cayman Island, between the George Town and Nort ...

1969 Pacific Hurricane Season
The 1969 Pacific hurricane season was an event in meteorology. It officially started on May 15, 1969, in the eastern Pacific and lasted until November 30, 1969. However, the first named storm, Ava, did not form until July 1, the latest date that the first named storm of a season formed. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. This season was below average in activity with ten named storms forming, of which only four reached hurricane strength, making it the third least active season, tied with the 1995 and 1979. There were no major hurricanes this year. Most of the storms that formed this season never approached land. Notable storms include Tropical Storm Emily and Hurricane Jennifer. The precursor disturbance of Tropical Storm Emily killed nine people in Mexico and left 100,000 homeless. Hurricane Jennifer was the only landfalling named storm of the season, causing one death.

Eye (cyclone)
The eye is a region of mostly calm weather at the center of tropical cyclones. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the ''eyewall'', a ring of towering thunderstorms where the most severe weather and highest winds occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is the location of the storm's minimum barometric pressure—where the atmospheric pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Sounding
Atmospheric sounding or atmospheric profiling is a measurement of vertical distribution of physical properties of the atmospheric column such as pressure, temperature, wind speed and wind direction (thus deriving wind shear), liquid water content, ozone concentration, pollution, and other properties. Such measurements are performed in a variety of ways including remote sensing and in situ observations. The most common in situ sounding is a radiosonde, which usually is a weather balloon, but can also be a rocketsonde. Remote sensing soundings generally use passive infrared and microwave radiometers: * airborne instruments * surface stations * Earth-observing satellite instruments such as AIRS and AMSU * observation of atmospheres on different planets, such as the Mars climate sounder on the Mars Reconnaissance Orbiter Direct methods Sensors that measure atmospheric constituents directly, such as thermometers, barometers, and humidity sensors, can be sent aloft on balloons, roc ...

Swan Islands, Honduras
The Swan Islands, or Islas Santanilla or Islas del Cisne, initially named Islas de las Pozas by Christopher Columbus in 1502, is a chain of three islands located in the northwestern Caribbean Sea, approximately off the coastline of Honduras, with a land area of . The islands are uninhabited except for a small permanent Honduran naval garrison stationed on Great Swan Island that maintains the Islas del Cisne Airport. Geography The Swan Islands lie within the exclusive economic zone of Honduras and belong to the Islas de la Bahía department of Honduras. They consist of three islands: * Great Swan Island (3 km long, 2 km2) * Little Swan Island (2.4 km long, 0.5 km wide, 1.2 km2) * Booby Cay (90 metres long, 70 m off the southwestern corner of Great Swan Island, deep Cayman Trench. History The Swan Islands were discovered by Christopher Columbus in 1502 and named the ''Islas de las Pozas''. In the 18th century, they were renamed the Swan Islands, ...

Ridge (meteorology)
A ridge or barometric ridge is a term in meteorology describing an elongated area of relatively high atmospheric pressure compared to the surrounding environment, without being a closed circulation. It is associated with an area of maximum anticyclonic curvature of wind flow. The ridge originates in the center of an anticyclone and sandwiched between two low-pressure areas, and the locus of the maximum curvature is called the ''ridge line''. This phenomenon is the opposite of a trough. Description Ridges can be represented in two ways: * On surface weather maps, the pressure isobars form contours where the maximum pressure is found along the axis of the ridge. * In upper-air maps, geopotential height isohypses form similar contours where the maximum defines the ridge. Related weather Given the direction of the winds around an anticyclonic circulation and the fact that weather systems move from west to east: *ahead of an upper-ridge, the airflow that comes from the polar regi ...

Lesser Antilles
The Lesser Antilles ( es, link=no, Antillas Menores; french: link=no, Petites Antilles; pap, Antias Menor; nl, Kleine Antillen) are a group of islands in the Caribbean Sea. Most of them are part of a long, partially volcanic island arc between the Greater Antilles to the north-west and the continent of South America."West Indies." ''Merriam-Webster's Geographical Dictionary'', 3rd ed. 2001. () Springfield, MA: Merriam-Webster Inc., p. 1298. The islands of the Lesser Antilles form the eastern boundary of the Caribbean Sea where it meets the Atlantic Ocean. Together, the Lesser Antilles and the Greater Antilles make up the Antilles. (Somewhat confusingly, the word Caribbean is sometimes used to refer only to the Antilles, and sometimes used to refer to a much larger region.) The Lesser and Greater Antilles, together with the Lucayan Archipelago, are collectively known as the West Indies. History after European arrival The Spanish were the first Europeans to arrive on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Circulation
Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth. The Earth's atmospheric circulation varies from year to year, but the large-scale structure of its circulation remains fairly constant. The smaller scale weather systems – mid-latitude depressions, or tropical convective cells – occur chaotically, and long-range weather predictions of those cannot be made beyond ten days in practice, or a month in theory (see chaos theory and the butterfly effect). The Earth's weather is a consequence of its illumination by the Sun and the laws of thermodynamics. The atmospheric circulation can be viewed as a heat engine driven by the Sun's energy and whose energy sink, ultimately, is the blackness of space. The work produced by that engine causes the motion of the masses of air, and in that process it redistributes the energy absorbed by the Earth's surface near ...
