Subtropical Cyclone
A subtropical cyclone is a weather system that has some characteristics of both tropical cyclone, tropical and extratropical cyclones. As early as the 1950s, meteorologists were uncertain whether they should be characterized as Tropical cyclone, tropical or extratropical cyclones. They were officially recognized and titled by the National Hurricane Center in 1972. Beginning in 2002, subtropical cyclones began receiving names from the official tropical cyclone lists in the North Atlantic hurricane, North Atlantic basin. Subtropical cyclones are also recognized in the South-West Indian Ocean tropical cyclone, South-West Indian Ocean and South Atlantic tropical cyclone, South Atlantic basins. There are two definitions currently used for subtropical cyclones depending on their location. Across the north Atlantic and southwest Indian Ocean, they require some central Convectional Precipitation, convection fairly near the center surrounding a warming core existing in the mid-levels of ...

Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system with a low-pressure area, 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 called a 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. A typhoon is the same thing which occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of or more. Tropical cyclones tropical cyclogenesis, typically form over large bodies of relatively warm water. They derive their energy through the evaporation of water ...

Subtropical Storm Alpha (1972)
Subtropical Storm Alpha (also called Alfa) was an List of off-season Atlantic hurricanes, off-season subtropical cyclone that impacted Georgia (U.S. state), Georgia in May 1972. It developed from a previously non-tropical cyclone in the western Atlantic Ocean, and initially it moved northeastward off the Carolinas. The storm turned southwestward due to a building ridge, and concurrently it intensified to become Subtropical Storm Alpha. It later moved ashore near Savannah, Georgia, Savannah, and it finally dissipated in the northeast Gulf of Mexico on May 29. It produced wave action and moderate rainfall along the coast. Damage totaled over $100,000 (1972 United States dollar, USD), and there were two associated deaths. Meteorological history Throughout May 1972, a series of weak troughs moved across the eastern United States. In the third week of the month, an upper-level cutoff low developed along one of these troughs, located southeast of the United States and removed fro ...

Subtropical Storm Alfa (1973)
The 1973 Atlantic hurricane season was a below average tropical cyclone season overall. Of the 24 tropical or subtropical cyclones which developed, only 8 became named storms, and of those, only 4 became hurricanes, with 1 reaching major hurricane status (Category 3 or higher) on the newly implemented Saffir–Simpson hurricane wind scale. The season officially began on June 1 and ended on November 30. These dates, adopted by convention, historically describe the period in each year when most tropical cyclones form in the North Atlantic. However, the formation of subtropical or tropical cyclones is possible at any time of the year, as demonstrated this season by the formation of multiple pre-season systems, none of which attained storm strength. The first named storm of the year, Hurricane Alice, did not form until July 1. Two of the season's landfalling storms had severe impacts. In August, Hurricane Brenda struck the eastern coast of the Bay of Campeche, killin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Storm Alpha (2005)
Tropical Storm Alpha was the 23rd tropical storm of the extremely active 2005 Atlantic hurricane season. It developed from Tropical Depression Twenty-Five in the eastern Caribbean Sea on October 22, 2005. As the 21 pre-designated storm names had been exhausted, it was given the first name on the auxiliary list, which utilized the letters of the Greek alphabet. This was the first hurricane season ever to trigger this naming protocol, and the only one until the 2020 season. During its brief life, Alpha moved west-northwestward and reached its peak intensity on October 23, but weakened as it neared landfall in the Dominican Republic that same day. Crossing the island of Hispaniola it weakened to a tropical depression, and persisted until October 24, when it dissipated. Its remnant low was absorbed by Hurricane Wilma's large circulation. Alpha dumped torrential rain on the island of Hispaniola, making it the eighth wettest storm to impact poverty-stricken Haiti. It ...

Subtropical Storm Alpha (2020)
Subtropical Storm Alpha was the first subtropical cyclone ever observed to make landfall in mainland Portugal. The twenty-second tropical or subtropical cyclone and twenty-first tropical cyclone naming, named storm of the extremely active and record-breaking 2020 Atlantic hurricane season, Alpha originated from a large Extratropical low, non-tropical low that was first monitored by the National Hurricane Center on 15 September. Initially not anticipated to transition into a tropical cyclone, the low gradually tracked south-southeastward for several days with little development. By early on 17 September, the low had separated from its frontal features and exhibited sufficient organization to be classified as a subtropical cyclone, as it approached the Iberian Peninsula, becoming a subtropical storm around that time. Alpha then made landfall just south of Figueira da Foz, Portugal during the evening of 18 September, then rapidly weakened as it moved over the mountain ...
