How do typhoons form?

The reasons for the formation of typhoons are:

Typhoons originate from the tropical sea surface, where the temperature is high, and a large amount of sea water is evaporated into the air, forming a low pressure center. With changes in air pressure and the movement of the earth itself, the inflowing air also rotates, forming a counterclockwise rotating air vortex, which is a tropical cyclone. As long as the temperature does not drop, this tropical cyclone will become stronger and stronger, and finally form a typhoon.

Extended information:

1. Typhoon is a category of tropical cyclone. According to the notice of the China Meteorological Administration on the Implementation of National Standards for Tropical Cyclone Levels GBT 19201-2006, tropical cyclones are divided into six categories based on the maximum wind speed on the ground near the center: super typhoon, severe typhoon, typhoon, severe tropical storm, tropical storm, and tropical depression. grade.

2. Typhoon According to relevant data on typhoon occurrence in recent years, the main rules and characteristics of typhoon occurrence are as follows: First, there is seasonality. Second, it is difficult to accurately predict the landing location of the typhoon center. Third, typhoons are rotating. Fourth, the damage is serious. Fifth, the occurrence of strong typhoons is often accompanied by heavy rains, large tides, and large tsunamis. Sixth, when a strong typhoon occurs, manpower is irresistible and can easily cause casualties.

3. When typhoons pass through, they often bring violent storms and rainy weather, causing huge waves on the sea surface, which seriously threatens navigation safety. The increased storm water caused by the typhoon landing may destroy crops, various construction facilities, etc., causing huge losses to people's lives and property.
