Typhoon (English: Typhoon) is a tropical cyclone. Tropical cyclone is a low-pressure vortex that occurs on the surface of tropical or subtropical ocean, and it is a powerful and profound "tropical weather system". In China, tropical cyclones in the northwest Pacific are classified into six grades according to the maximum average wind speed near the center of the surface layer, and the wind force near the center reaches 12 or above, which is collectively called typhoon.

Correlation of typhoon definition

Typhoon is a kind of tropical cyclone. Typhoons often bring strong winds, heavy rains and storm surges. Meteorologically, according to the definition of the World Meteorological Organization, tropical cyclones with sustained wind speed above 12 (i.e. 32.7m to 41.4m per second) are called typhoons or hurricanes. The word "typhoon" is pronounced as "gale" in China Cantonese.

After spreading abroad, it was sent back to China and translated into a typhoon; It is also said that it evolved from "Fengtai" in Minnan dialect. Typhoons usually form in tropical areas (such as the North and South Pacific, the North Atlantic and the Indian Ocean) 3-5 latitudes away from the equator, and their movements are mainly affected by large-scale weather systems, and eventually dissipate at sea, or degenerate into temperate cyclones, or dissipate after landing.
