Tropical Depression One (1979)
Tropical Depression One brought severe flooding to Jamaica in June 1979. The second tropical cyclone of the Atlantic hurricane season, the depression developed from a tropical wave to the south of Grand Cayman on June 11. Tracking generally northward, the depression passed west of Jamaica. On June 12, the depression peaked with maximum sustained winds of 35 mph (55 km/h), never having reached tropical storm status. The following day, it made landfall in Cuba, where minimal impact was recorded. Early on June 14, the depression emerged into the western Atlantic Ocean and then moved parallel to the east coast of Florida for a few days. The depression made another landfall in South Carolina on June 16 and dissipated shortly thereafter. The slow movement of the depression to the west of Jamaica resulted in torrential rainfall, peaking at in Friendship, a city in Westmoreland Parish. Throughout western Jamaica, about 1,000 homes were destroyed or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 landed on the ...

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, Ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southeastern United States
The Southeastern United States, also referred to as the American Southeast or simply the Southeast, is a geographical region of the United States. It is located broadly on the eastern portion of the southern United States and the southern portion of the eastern United States. It comprises at least a core of states on the lower East Coast of the United States and eastern Gulf Coast. Expansively, it reaches as far north as West Virginia and Maryland (bordered to north by the Ohio River and Mason–Dixon line), and stretching as far west as Arkansas and Louisiana. There is no official U.S. government definition of the region, though various agencies and departments use different definitions. Geography The U.S. Geological Survey considers the Southeast region to be the states of Alabama, Florida, Georgia, Arkansas, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee, plus Puerto Rico and the United States Virgin Islands.

Venezuela, Cuba
Venezuela () is a municipality and town in the Ciego de Ávila Province of Cuba. It is located immediately south of the provincial capital, Ciego de Ávila. History The territory in the colonial period of what is Venezuela was characterized by the sugar production headed by the Resurrección and La Soledad mills, Cuban War of Independence, it witnessed the struggle of the Mambises who demonstrated their combative audacity by mocking the defensive system of the Trocha from Júcaro to Morón, among its protagonists they found Máximo Gómez, who crossed it on January 6, 1875. When the struggles for independence resumed, it was the scene of different actions by Mambi chiefs such as Simón Reyes, known as the Eagle of La Trocha, and the arrival of an expedition through the Palo Alto area received by Generalissimo Gómez. In the Neocolonial stage, sugar production, port activities, livestock and the cultivation of minor fruits constituted the fundamental economic lines, sugar producti ...

Rainbands
A rainband is a cloud and precipitation structure associated with an area of rainfall which is significantly elongated. Rainbands can be stratiform or convective, and are generated by differences in temperature. When noted on weather radar imagery, this precipitation elongation is referred to as banded structure. Rainbands within tropical cyclones are curved in orientation. Rainbands of tropical cyclones contain showers and thunderstorms that, together with the eyewall and the eye, constitute a hurricane or tropical storm. The extent of rainbands around a tropical cyclone can help determine the cyclone's intensity. Rainbands spawned near and ahead of cold fronts can be squall lines which are able to produce tornadoes. Rainbands associated with cold fronts can be warped by mountain barriers perpendicular to the front's orientation due to the formation of a low-level barrier jet. Bands of thunderstorms can form with sea breeze and land breeze boundaries, if enough moisture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weather Radar
Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. During World War II, radar operators discovered that weather was causing echoes on their screen, masking potential enemy targets. Techniques were developed to filter them, but scientists began to study the phenomenon. Soon after the war, surplus radars were used to detect precipitation. Since then, weather radar has evolved on its own and is now used by national weather services, research departments in universities, and in television stations' weather departments. Raw images are routinely used and special ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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