Hurricane Alberto (2000)
Hurricane Alberto was the farthest-travelling tropical cyclone on record in the Atlantic Ocean. The third tropical cyclone, first named storm, and first hurricane of the 2000 Atlantic hurricane season, Alberto developed near the western coast of Africa from a tropical wave on August 3. Initially a tropical depression, it strengthened into Tropical Storm Alberto early on August 4. While briefly turning westward on August 6, Alberto attained hurricane status. The cyclone continued to track west-northwestward, and by early the following day, reached an initial peak with winds of . Shortly thereafter, Alberto re-curved northwestward and began encountering increased wind shear. As a result, Alberto weakened back to a tropical storm on August 9. However, the system quickly re-strengthened as winds became more favorable, and early on August 10, Alberto became a hurricane again. The storm gradually curved northward and north-northeastward between August 11 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Ethiopian Highlands
The Ethiopian Highlands is a rugged mass of mountains in Ethiopia in Northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below , while the summits reach heights of up to . It is sometimes called the Roof of Africa due to its height and large area. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrea. History In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval early modern state, whence the coffee plant was exported to the Arabian Peninsula. The land of the former kingdom is mountainous with stretches of forest. The land is very fertile, capable of three harvests a year. The term ''coffee'' derives from the ar, قهوة, italic=no ()''Oxford English Dictionary'', 1st ed. "coffee, ''n.''" Oxford University Press (Oxford), 1891. and is traced to Kaffa.

1980 Atlantic Hurricane Season
The 1980 Atlantic hurricane season featured nine hurricanes, the most since 1969. The season officially began on June 1, 1980, and lasted until November 30, 1980. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic Ocean. The season was fairly active, with sixteen tropical cyclones forming, eleven of which intensified into a tropical storm. It was the first time since the 1971 season that there were no active tropical cyclones in the Atlantic basin during the month of June. The season occurred during an ENSO-neutral phase, having neither an El Niño nor a La Niña. Three tropical cyclones in the Atlantic Ocean in 1980 were notable. Hurricane Allen was the then-earliest Category 5 hurricane on record, reaching that intensity on August 5. The storm devastated portions of the Caribbean, Mexico, and the United States. Overall, Allen caused about $2.57 billion and at least 269 deaths. Tropical St ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1899 Hurricane San Ciriaco
The 1899 San Ciríaco hurricane, also known as the 1899 Puerto Rico Hurricane or The Great Bahamas Hurricane of 1899, was the longest-lived Atlantic hurricane on record, and the second-longest-lived tropical cyclone globally on record (in terms of tropical duration) after 1994's Hurricane John in the Pacific. It was also one of the deadliest Atlantic hurricanes in recorded history, with an estimated 3,800 fatalities. The third tropical cyclone and first major hurricane of the season, this storm was first observed southwest of Cape Verde on August 3. It slowly strengthened while heading steadily west-northwestward across the Atlantic Ocean and reached hurricane status by late on August 5. During the following 48 hours, it deepened further, reaching Category 4 on the modern day Saffir–Simpson hurricane wind scale (SSHWS) before crossing the Leeward Islands on August 7. Later that day, the storm peaked with winds of 150 mph (240 km/h). The sto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Atlantic Hurricane Records
As of March 2022, there have been 1,631 tropical cyclones of at least tropical storm intensity, and 935 of hurricane intensity within the Atlantic Ocean since 1851, the first Atlantic hurricane season to be included in the official Atlantic tropical cyclone record. Though a majority of these cyclones have fallen within climatological averages, prevailing atmospheric conditions occasionally lead to anomalous tropical systems which at times reach extremes in statistical record-keeping including in duration and intensity. The scope of this list is limited to tropical cyclone records solely within the Atlantic Ocean and is subdivided by their reason for notability. Tropical cyclogenesis Most activeleast active Atlantic hurricane seasons Most Atlantic hurricane seasons prior to the weather satellite era include seven or fewer recorded tropical storms or hurricanes. As the usage of satellite data was not available until the mid-1960s, early storm counts are less reliable. Before the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dakar
Dakar ( ; ; wo, Ndakaaru) (from daqaar ''tamarind''), is the capital and largest city of Senegal. The city of Dakar proper has a population of 1,030,594, whereas the population of the Dakar metropolitan area is estimated at 3.94 million in 2021. The area around Dakar was settled in the 15th century. The Portuguese established a presence on the island of Gorée off the coast of Cap-Vert and used it as a base for the Atlantic slave trade. France took over the island in 1677. Following the abolition of the slave trade and French annexation of the mainland area in the 19th century, Dakar grew into a major regional port and a major city of the French colonial empire. In 1902, Dakar replaced Saint-Louis as the capital of French West Africa. From 1959 to 1960, Dakar was the capital of the short-lived Mali Federation. In 1960, it became the capital of the independent Republic of Senegal. History The Cap-Vert peninsula was settled no later than the 15th century, by the Lebu peop ...

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] |
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 ...

Hurricane Alberto 19 Aug 2000 1415Z
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, whirli ...

Subtropical Ridge
The horse latitudes are the latitudes about 30 degrees north and south of the Equator. They are characterized by sunny skies, calm winds, and very little precipitation. They are also known as Subtropics, subtropical ridges, or highs. It is a high-pressure area at the divergence of trade winds and the westerlies. Origin of the term A likely and documented explanation is that the term is derived from the "dead horse" ritual of seamen (see Flogging a dead horse#Earlier meaning, Beating a dead horse). In this practice, the seaman paraded a straw-stuffed effigy of a horse around the deck before throwing it overboard. Seamen were paid partly in advance before a long voyage, and they frequently spent their pay all at once, resulting in a period of time without income. If they got advances from the ship's paymaster, they would incur debt. This period was called the "dead horse" time, and it usually lasted a month or two. The seaman's ceremony was to celebrate having worked off the "d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
