What are the hazards caused by typhoons?

Typhoon is a disastrous weather system with strong destructive power, and its harmfulness mainly includes three aspects:

First, it brings great wind damage. The maximum wind force near the typhoon center is generally above 8, which will bring great disasters to the affected areas.

The second is the rainstorm disaster. Typhoon is one of the strongest rainstorm weather systems. Generally, it can produce rainfall of 1.50 mm ~ 300 mm in the area it passes through, and a few typhoons can produce torrential rain above 1.000 mm. Typhoon No.3 1975 produced torrential rain in the upper reaches of Huaihe River, creating the extreme value of rainstorm in Chinese mainland and forming the "75.8" flood in Henan.

The third is the storm surge disaster. Generally, typhoons will increase water in coastal waters, and the maximum increase in water in Jiangsu Province can reach 3 meters. Typhoon "9608" and "97 1 1" increased water, which made Jiangsu's coastal areas along the Yangtze River have a super-historical climax.

Typhoon often brings stormy weather when crossing the border, causing huge waves on the sea surface, which seriously threatens the safety of navigation. After the typhoon landed, the storm surge may destroy crops and various building facilities, causing great losses to people's lives and property.
