According to the introduction of typhoon, please summarize three kinds of disastrous weather caused by typhoon.

Typhoon is a very destructive and disastrous weather system, but sometimes it can also play a beneficial role in eliminating drought. Its harmfulness mainly includes three aspects:

(1) Strong wind. The maximum wind force near the typhoon center is generally above 8.

② Heavy rain. Typhoon is one of the strongest rainstorm weather systems. Generally, it can produce rainfall of 150 mm ~ 300 mm in the area it passes through, and a few typhoons can produce torrential rain above1000 mm. The rainstorm caused by typhoon 1975 in the upper reaches of Huaihe River created the extreme value of rainstorm in Chinese mainland and caused the "75.8" flood in Henan.

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