Nearly 2 million people have died globally due to tropical cyclones. Despite their devastating effects, tropical cyclones are also beneficial, by potentially bringing rain to dry areas and moving heat from the tropics poleward. Out at sea, ships take advantage of their known characteristics by navigating through their weaker, western half.
Tropical cyclones are typically between 100 and 2,000 km (62 and 1,243 mi) in diameter. The strong rotating winds of a tropical cyclone are a result of the conservation of angular momentum imparted by the Earth's rotation as air flows inwards toward the axis of rotation. As a result, cyclones rarely form within 5° of the equator.
A tropical cyclone rainfall climatology can be used to help forecast current or upcoming tropical cyclone impacts. The degree of a tropical cyclone rainfall impact depends upon speed of movement, storm size, and degree of vertical wind shear. One of the most significant threats from tropical cyclones is heavy rainfall. Large, slow moving, and ...
Tropical cyclones regularly affect the coastlines of most of Earth's major bodies of water along the Atlantic, Pacific, and Indian oceans. Also known as hurricanes, typhoons, or other names, tropical cyclones have caused significant destruction and loss of human life, resulting in about 2 million deaths since the 19th century.
Climate change may affect tropical cyclones in a variety of ways: an intensification of rainfall and wind speed, a decrease in overall frequency, an increase in frequency of very intense storms and a poleward extension of where the cyclones reach maximum intensity are among the possible consequences of human-induced climate change.
India's western coast, bordering the more placid Arabian Sea, experiences cyclones only rarely; these mainly strike Gujarat and, less frequently, Kerala and sometimes Odisha. In terms of damage and loss of life, the 1999 Odisha cyclone, a super cyclone that struck Odisha on 29 October 1999, was the worst in more than a quarter-century.
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]
The smallest tropical cyclone was Cyclone Ogni, which struck the Andhra Pradesh coast on October 30, 2008. The cyclone's diameter was only 100 km (62 mi). [36] The largest tropical cyclone was the 1999 Odisha Cyclone, which strike the coast of Odisha. [8] [37] The wettest tropical cyclone was Severe Cyclonic Storm ARB 01 (2004). One of the ...
