In meteorology, a cyclone (/ ˈ s aɪ. k l oʊ n /) is a large air mass that rotates around a strong center of low atmospheric pressure, counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere as viewed from above (opposite to an anticyclone).
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 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 ...
The area just northeast of the Philippines is the most active place on Earth for tropical cyclones to exist. Across the Philippines themselves, activity reaches a minimum in February, before increasing steadily through June and spiking from July through October, with September being the most active month for tropical cyclones across the ...
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 ...
