Why is there a typhoon in summer?

Typhoon is a kind of tropical cyclone. Meteorology, according to the definition of the World Meteorological Organization, the tropical cyclone center with sustained wind speed of 12 to 13 (i.e. 32.7m to 41.4m per second) is called typhoon or hurricane, and the name of hurricane is used in the North Atlantic and the East Pacific. In the western part of the North Pacific (north of the equator, west of international date line, east of E 100), it is synonymous with typhoon.

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.

With the arrival of winter, the direct point of the sun moves south, and the hot weather and wind belt move south. When the northern hemisphere gets cold, the conditions for the formation and development of typhoons disappear. So there are typhoons in hot and humid summer.
