In Asia, tropical cyclones from the Indian and Pacific oceans regularly affect some of the most populated countries on Earth. In 1970, a cyclone struck Bangladesh , then known as East Pakistan, producing a 6.1 m (20 ft) storm surge that killed at least 300,000 people; this made it the deadliest tropical cyclone on record.
Although the North Indian Ocean is a relatively inactive basin, extremely high population densities in the Ganges and Ayeyarwady Deltas mean that the deadliest tropical cyclones in the world have formed here, including the 1970 Bhola cyclone, which killed 500,000 people.
A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
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 map of all tropical cyclone tracks, encompassing the period between the years 1985 and 2005. This is a list of wettest tropical cyclones by country , using all known available sources. Data is most complete for Australia, Cuba, Dominican Republic, Japan, Hong Kong , Mexico, Taiwan, Micronesia 's Yap and Chuuk , and the United States, with ...
A total of 21 tropical cyclones have peaked at Category 5 strength in the South Pacific tropical cyclone basin, which is denoted as the part of the Pacific Ocean to the south of the equator and to the east of 160°E. 20 of these tropical cyclones have been classified as Category 5 on the Australian tropical cyclone intensity scale, while Severe ...
A "Typhoon" is a tropical cyclone located in the North-west Pacific Ocean which has the most cyclonic activity and storms occur year-round. 2. A "Hurricane" is also a tropical cyclone located at the North Atlantic Ocean or North-east Pacific Ocean which have an average storm activity and storms typically form between May 15 and November 30. 3.
Severe tropical cyclones defoliate tropical forest canopy trees, remove vines and epiphytes from the trees, break tree crown stems, and cause tree falls. The degree of damage they do along their paths, at a landscape level (i.e. > 10 kilometres (6.2 mi)), can be catastrophic yet variable and patchy. [38]
