Hurricane Joaquin
Hurricane Joaquin (, ) was a powerful tropical cyclone that devastated several districts of The Bahamas and caused damage in the Turks and Caicos Islands, parts of the Greater Antilles, and Bermuda. It was also the strongest Atlantic hurricane of non-tropical origin recorded in the satellite era. The tenth named storm, third hurricane, and second major hurricane of the 2015 Atlantic hurricane season, Joaquin evolved from a non-tropical low to become a tropical depression on September 28, well southwest of Bermuda. Tempered by unfavorable wind shear, the depression drifted southwestward. After becoming a tropical storm the next day, Joaquin underwent rapid intensification, reaching hurricane status on September 30 and Category 4 major hurricane strength on October 1. Meandering over the southern Bahamas, Joaquin's eye passed near or over several islands. On October 3, the hurricane weakened somewhat and accelerated to the northeast. Abrupt re-intensification ensued later that d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Bahamas
The Bahamas (), officially the Commonwealth of The Bahamas, is an island country within the Lucayan Archipelago of the West Indies in the North Atlantic. It takes up 97% of the Lucayan Archipelago's land area and is home to 88% of the archipelago's population. The archipelagic state consists of more than 3,000 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola (split between the Dominican Republic and Haiti) and the Turks and Caicos Islands, southeast of the U.S. state of Florida, and east of the Florida Keys. The capital is Nassau on the island of New Providence. The Royal Bahamas Defence Force describes The Bahamas' territory as encompassing of ocean space. The Bahama Islands were inhabited by the Lucayans, a branch of the Arawakan- speaking Taíno, for many centuries. Christopher Columbus was the first European to see the islands, making his first landfall in the "New World" in 1492 when he ...

Cold-core Low
A cold-core low, also known as an upper level low or cold-core cyclone, is a cyclone aloft which has an associated cold pool of air residing at high altitude within the Earth's troposphere, without a frontal structure. It is a low pressure system that strengthens with height in accordance with the thermal wind relationship. If a weak surface circulation forms in response to such a feature at subtropical latitudes of the eastern north Pacific or north Indian oceans, it is called a subtropical cyclone. Cloud cover and rainfall mainly occurs with these systems during the day. Severe weather, such as tornadoes, can occur near the center of cold-core lows. Cold lows can help spawn cyclones with significant weather impacts, such as polar lows, and Kármán vortices. Cold lows can lead directly to the development of tropical cyclones, owing to their associated cold pool of air aloft or by acting as additional outflow channels to aid in further development.

Storm Surge
A storm surge, storm flood, tidal surge, or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low-pressure weather systems, such as cyclones. It is measured as the rise in water level above the normal tidal level, and does not include waves. The main meteorological factor contributing to a storm surge is high-speed wind pushing water towards the coast over a long fetch. Other factors affecting storm surge severity include the shallowness and orientation of the water body in the storm path, the timing of tides, and the atmospheric pressure drop due to the storm. There is a suggestion that climate change may be increasing the hazard of storm surges. Some theorize that as extreme weather becomes more intense and sea level rises due to climate change, storm surge is expected to cause more risk to coastal populations. Communities and governments can adapt by building hard infrastructure, like surge barriers, soft infrastructure, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 presum ...

Rum Cay
Rum Cay (formerly known as Mamana and Santa Maria de la Concepción) is an island and district of the Bahamas. It measures in area, it is located at Lat.: N23 42' 30" - Long.: W 74 50' 00". It has many rolling hills that rise to about 120 feet (37 m). The island is believed to have acquired its modern name from a shipwrecked cargo of rum. The main settlement is Port Nelson. Its population was recorded as 99 and as 30 . Before 1996 the island was part of a combined district of San Salvador and Rum Cay. The population of Rum Cay as of 2015 is 53. Location Rum Cay is 20 miles (32 km) southwest of San Salvador Island. History Aboriginals Rum Cay was called Mamana by the native Lucayans. In the north there is a cave containing Lucayan drawings and carvings. Various artifacts from the Arawak period have been found by farmers in the fertile soil, which the natives enriched with bat guano. Spanish Some writers, such as Samuel Eliot Morison, identified Rum Cay as the site o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crooked Island, Bahamas
Crooked Island is an island and district, part of a group of Bahamian islands defining a large, shallow lagoon called the Bight of Acklins, of which the largest are Crooked Island in the north and Acklins in the south-east, and the smaller are Long Cay (once known as Fortune Island) in the north-west, and Castle Island in the south. History The islands were settled by American Loyalists in the late 1780s who set cotton plantations using over 1,000 slaves. After the abolition of slavery in the British Empire these became uneconomical, and the replacement income from sponge Sponges, the members of the phylum Porifera (; meaning 'pore bearer'), are a basal animal clade as a sister of the diploblasts.

Acklins
Acklins is an island and district of the Bahamas. It is one of a group of islands arranged along a large, shallow lagoon called the Bight of Acklins, of which the largest are Crooked Island () in the north and Acklins () in the southeast, and the smaller are Long Cay (once known as Fortune Island, ()) in the northwest, and Castle Island in the south. History The islands were settled by American Loyalists in the late 1780s who set up cotton plantations maintained by over 1,000 slaves. After the abolition of slavery in the British Empire the plantations became uneconomical, and the replacement income from sponge diving has now dwindled as well with the rest of the natural sponge industry after the advent of synthetics. The inhabitants now live by fishing and small-scale farming. Although Acklins Island has relatively few historical landmarks, there are some noteworthy places. Acklins is home to numerous Lucayan people sites. An ancient site, thought to be one of the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone Warnings And Watches
Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Western hemisphere New tropical cyclone position and forecast information is available at least every twelve hours in the Southern Hemisphere and at least every six hours in the Northern Hemisphere from Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers. In conjunction with the National Hurricane Center, the national meteorological and hydrological services of Central America, the northern Atlan ...

Maximum Sustained Wind
The maximum sustained wind associated with a tropical cyclone is a common indicator of the intensity of the storm. Within a mature tropical cyclone, it is found within the eyewall at a distance defined as the radius of maximum wind, or RMW. Unlike gusts, the value of these winds are determined via their sampling and averaging the sampled results over a period of time. Wind measuring has been standardized globally to reflect the winds at above the Earth's surface, and the maximum sustained wind represents the highest average wind over either a one-minute (US) or ten-minute time span (see the definition, below), anywhere within the tropical cyclone. Surface winds are highly variable due to friction between the atmosphere and the Earth's surface, as well as near hills and mountains over land. Over the ocean, satellite imagery determines the value of the maximum sustained winds within a tropical cyclone. Land, ship, aircraft reconnaissance observations, and radar imagery can ...

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 atmospheri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
