Hurricane Betsy (1956)
Hurricane Betsy, known as Hurricane Santa Clara in Puerto Rico, was the first North Atlantic hurricane to make landfall in Puerto Rico in 24 years. The third tropical cyclone of the 1956 Atlantic hurricane season, Betsy developed from a tropical wave on August 9 to the east of the Lesser Antilles. It rapidly developed into a major hurricane before striking Guadeloupe. There, Betsy heavily damaged 1000 houses and left severe crop destruction, and there were 18 deaths in the territory. As Betsy continued into the northeastern Caribbean, it capsized a ship, killing its crew of two. On August 12, Betsy struck southeastern Puerto Rico and quickly crossed the island. Damage was heaviest where it moved ashore and in the territory's central portion, and throughout Puerto Rico there were 15,023 houses that were destroyed by Betsy. Multiple locations reported heavy crop damage, including Camuy which reported a complete loss of the corn crop. Hurricane Betsy ...

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.

Tropical Cyclogenesis
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment. Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least ), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in most basins. Climate cycles such as ENSO and the Madden–Julian oscillation modulate the timing and frequency of tropical cyclone development. There is a limit on tropical cyclone i ...

Trough (meteorology)
A trough is an elongated region of relatively low atmospheric pressure without a closed isobaric contour that would define it as a low pressure area. Since low pressure implies a low height on a pressure surface, troughs and ridges refer to features in an identical sense as those on a topographic map. Troughs may be at the surface, or aloft. Near-surface troughs sometimes mark a weather front associated with clouds, showers, and a wind direction shift. Upper-level troughs in the jet stream (as shown in diagram) reflect cyclonic filaments of vorticity. Their motion induces upper-level wind divergence, lifting and cooling the air ahead (downstream) of the trough and helping to produce cloudy and rain conditions there. Unlike fronts, there is not a universal symbol for a trough on a surface weather analysis chart. The weather charts in some countries or regions mark troughs by a line. In the United States, a trough may be marked as a dashed line or bold line. In the UK, Hong Kong ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barometric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760mm Hg, 29.9212 inchesHg, or 14.696psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely 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 atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's gravi ...

San Salvador Island
San Salvador Island (known as Watling's Island from the 1680s until 1925) is an island and district of The Bahamas. It is widely believed that during Christopher Columbus's first expedition to the New World, this island was the first land he sighted and visited on 12 October 1492. He named it ''San Salvador'' after Christ the Saviour. Columbus's records indicate that the native Lucayan inhabitants of the territory, who called their island Guanahaní, were "sweet and gentle". History When he made landfall on the small island of San Salvador in October 1492, Columbus thought he had reached the East Indies, which was precisely his quest: to find an all-water route to the Orient so that European traders of precious spices could maximise their profits by cutting out Muslim middlemen. Additionally and more specifically, he was working on behalf of the Spanish to surpass the Portuguese, who had established trade routes around the Horn of Africa, a trans-Atlantic route being presume ...

Grand Turk Island
Grand Turk Island is an island in the Turks and Caicos Islands. It is the largest island in the Turks Islands (the smaller of the two archipelagos that make up the island territory) with . Grand Turk contains the territory's capital, Cockburn Town, and the JAGS McCartney International Airport. The island is the administrative, historic, cultural and financial center of the territory and has the second-largest population of the islands at approximately 4,831 people in 2012. The name comes from a species of cactus on the island, the Turk's Cap Cactus (''Melocactus intortus''), which has a distinctive cap, reminiscent of an Ottoman fez. History The Lucayan people were the indigenous people of the island, who called it ''Abawana,'' meaning "the First Small Land"''.'' The Spanish later called it Amuana. Grand Turk was first colonised in 1681 by Bermudians, who set up the salt industry in the islands. In 1766 it became the capital of the country. For some time, at least until the ...

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] |
