What does a typhoon look like?

Typhoon is a very large cyclone, and the central air pressure is low, which causes the surrounding air to move to the center and the airflow to rise, which will bring strong winds, heavy rains and storm surges.

Typhoon is a kind of 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.

Typhoons often bring strong winds, heavy rains and storm surges, which not only bring disasters to human beings, but also bring benefits to human beings. Typhoon has brought abundant fresh water resources to human beings, which is of great significance for improving fresh water supply and ecological environment. In addition, typhoons also keep the global cold and heat relatively balanced; The climate in the equatorial region is hot. If the typhoon does not disperse this heat, the tropics will be hotter, the frigid zone will be colder and the temperate zone will disappear from the earth.

The origin of typhoon name:

Wang Cunzhong's article "The Origin and Naming Principles of Typhoon Terms" was published in Volume 8, No.2, 2006, and discussed the historical evolution of the word "typhoon". The author believes that in ancient times, people called typhoons hurricanes, and it was not until the late Ming and early Qing dynasties that the name "typhoon" was taken as a general term for cold wave gale or non-typhoon gale.

The word "typhoon" was pronounced as "gale" in Cantonese in China, and was translated into typhoon in China after it spread abroad. In the past, there were frequent storms along the southeast coast of China, which were called "gale" by local fishermen and later turned into typhoons. It is also said that it evolved from "Fengtai" in Minnan dialect.

Typhoon in Greek is not only the name of Fengshen, but also a common noun, meaning "cyclone, typhoon", which has been borrowed from Arabic.
