The Cook Islands in the South Pacific Ocean are affected by about 1.8 tropical cyclones each year, mostly during El Niño events. Cyclones are the islands' most frequent form of natural disaster. In 1997, Cyclone Martin killed 19 people in the archipelago, making it the deadliest storm there on record. In 2005, five tropical cyclones affected ...
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 and South Pacific, comparable storms are referred to as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms".
Tropical cyclones develop or strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor contained in the moist air. They are fueled by a different heat mechanism than other cyclonic windstorms such as nor'easters , European windstorms , and polar lows .
A typhoon is a type of tropical cyclone that occurs in the Northwest Pacific Ocean, specifically between 100°E and 180°E longitude. It is characterized by a well-defined circular structure with ...
Tracks of all tropical cyclones in the northern Atlantic Ocean between 1980 and 2005. This region includes the North Atlantic Ocean, the Caribbean Sea, and the Gulf of Mexico. Tropical cyclone formation here varies widely from year to year, ranging from one to over twenty-five per year. [6]
Most often, storms that occur in the area are weak and often decline in strength upon entry. The only land masses impacted by tropical cyclones in this region are Hawaii and Johnston Atoll. Due to the small size of the islands in relation to the Pacific Ocean, direct hits and landfalls are rare.
A dangerous weather phenomenon called a bomb cyclone that occurs in mid-latitudes - between Earth's tropics and the polar regions - can bring strong and damaging winds, torrential rains, heavy ...
Typically, tropical cyclones form at least 5.0 degrees of latitude north and south of the equator, or at least 300 nautical miles (556 km, 345 mi) of the equator. Despite the presence of sufficiently warm sea surface temperatures and generally low wind shear , tropical cyclogenesis is uncommon at these latitudes, due to a lack of the Coriolis ...
