Is the typhoon high or low?
Strong tropical cyclones not only form strong winds and huge waves, but also often accompany with heavy rains and storm surges, causing serious disasters.
How is a typhoon formed?
Typhoon originated in tropical ocean, where the temperature is high and a large amount of seawater is evaporated into the air, forming a low pressure center. With the change of air pressure and the movement of the earth itself, the inflow of air also rotates, forming a counterclockwise air vortex, which is a tropical cyclone. As long as the temperature does not drop, this tropical cyclone will get stronger and stronger, and finally a typhoon will form.
Typhoon classification
In China, tropical cyclones in the South China Sea and the Northwest Pacific are classified into six grades according to the maximum average wind speed near the bottom center, and the wind near the center reaches 12 or above, which is collectively called typhoon. According to its intensity, typhoons are divided into six grades: tropical depression, tropical storm, strong tropical storm, typhoon, strong typhoon and super typhoon.
