Hurricane Lili (1996)
Hurricane Lili was a relatively long-lived hurricane of the 1996 Atlantic hurricane season that affected countries from Central America to the United Kingdom. Lili formed on October 14 from a tropical wave, which emerged from the coast of west Africa on October 4. After the storm formed, further strengthening of Lili was gradual, first to tropical storm status on October 16 and then to hurricane status on October 17. The next day, Lili struck Cuba and moved across the central portion of the island, the first hurricane to hit the country since Hurricane Kate in 1985. After emerging into the Atlantic Ocean, the hurricane accelerated northeastward, briefly peaking as a category 3 hurricane on the Saffir-Simpson Hurricane Scale near the Bahamas. For almost an entire week, Hurricane Lili oscillated in intensity while fluctuating several times in forward speed. About two weeks passed before Lili transitioned into an extratropical storm north of the Azores on O ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 cyclo ...

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, Hon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Exuma
Exuma is a district of The Bahamas, consisting of over 365 islands, also called cays. The largest of the cays is Great Exuma, which is 37 mi (60 km) in length and joined to another island, Little Exuma, by a small bridge. The capital and largest town in the district is George Town (population 1,437). It was founded 1793 and located on Great Exuma. Near the town, but on Little Exuma, the Tropic of Cancer runs across Pelican Beach lending it another name: Tropic of Cancer Beach. Its white sand and turquoise waters make it a world-famous destination. The entire island chain is 130 mi (209 km) long and 72 sq mi (187 km²) in area. Great Exuma island has an area of 61 sq mi (158 km²) while Little Exuma has an area of 11 sq mi (29 km²). Between 2000 and 2010, the population of Exuma more than doubled, reflecting the construction of large and small resort properties and the related direct air traffic to Great Exuma from locations as distant as To ...

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 p ...

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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matanzas Province
Matanzas () is one of the provinces of Cuba. Major towns in the province include Cárdenas, Colón, Jovellanos and the capital of the same name, Matanzas. The resort town of Varadero is also located in this province. Among Cuban provinces, Matanzas is one of the most industrialized, with petroleum wells, refineries, supertanker facilities, and 21 sugar mills to process the harvests of the fields of sugarcane in the province. Geography The second largest in Cuba, Matanzas province is largely flat, with its highest point (Pan de Matanzas) at only 380m above sea level. The north-western coast is largely rocky, with a few beaches, while the north-eastern coast has numerous small cays of its coast (part of Sabana-Camaguey Archipelago), and scrubland and mangroves near the shoreline. Cuba's northernmost point is located in on Hicacos Peninsula. The southern coast has one of Cuba's most distinctive features: an enormous marsh, Ciénaga de Zapata that covers both the southern par ...

Isla De La Juventud
Isla de la Juventud (; en, Isle of Youth) is the second-largest Cuban island (after Cuba's mainland) and the seventh-largest island in the West Indies (after mainland Cuba itself, Hispaniola, Jamaica, Puerto Rico, Trinidad, and Andros Island). The island was called the Isle of Pines ( es, Isla de Pinos) until 1978. It has an area and is south of the island of Cuba, across the Gulf of Batabanó. The island lies almost directly south of Havana and Pinar del Río and is a Special Municipality (), not part of any province and is therefore administered directly by the central government of Cuba. The island has only one municipality, also named Isla de la Juventud. The largest of the 350 islands in the Canarreos Archipelago (''Archipiélago de los Canarreos''), the island has an estimated population of 83,544 (in 2019). The capital and largest city is Nueva Gerona in the north, and the second largest and oldest city is Santa Fe in the interior. Other communities include Col ...

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, ...

Coordinated Universal Time
Coordinated Universal Time or UTC is the primary time standard by which the world regulates clocks and time. It is within about one second of mean solar time (such as UT1) at 0° longitude (at the IERS Reference Meridian as the currently used prime meridian) and is not adjusted for daylight saving time. It is effectively a successor to Greenwich Mean Time (GMT). The coordination of time and frequency transmissions around the world began on 1 January 1960. UTC was first officially adopted as CCIR Recommendation 374, ''Standard-Frequency and Time-Signal Emissions'', in 1963, but the official abbreviation of UTC and the official English name of Coordinated Universal Time (along with the French equivalent) were not adopted until 1967. The system has been adjusted several times, including a brief period during which the time-coordination radio signals broadcast both UTC and "Stepped Atomic Time (SAT)" before a new UTC was adopted in 1970 and implemented in 1972.
