Is Shanghai greatly affected by typhoons?

Typhoon Du Julie had a great impact on Shanghai.

Typhoon Du intensified into a super typhoon on the evening of 24th. Although the intensity of the typhoon will be weakened after landing due to many land obstacles and large terrain fluctuations, Shanghai is still affected to some extent because of its short distance. From 27th to 29th, Shanghai was mainly affected by the peripheral circulation of Typhoon Du. The cloud system increases, the wind increases, the temperature drops slightly, and the maximum temperature drops to about 30℃.

During the passage of Typhoon Du Julie, there were showers or thunderstorms in Shanghai. The rainfall in some areas can reach 30-50 mm, and the maximum hourly rainfall intensity can reach 20-40 mm. Due to the typhoon, the wind will also increase. The wind speed can reach 5, and the gust is 6-7. The winds along the Yangtze River and rivers and lakes can reach 6, and the gusts are 7-8.

Introduction of typhoon structure:

1, typhoon eye area

The typhoon eye area is very strange, where the wind is very small and the weather is sunny, with an average diameter of about 40 kilometers. The sailors involved humorously called Typhoon Eye "Xanadu".

2. Cloud wall area

The cloud wall area around the typhoon eye is expected to be tens of kilometers wide and tens of kilometers high, also known as the eye wall. The cloud wall is towering here, the wind is howling, the rain is pouring, the sea is churning, and the weather is the worst.

3. Spiral rain belt area

Outside the cloud wall is a spiral rain belt. There are several rain (clouds) bands that gather spirally around the eye wall. The bandwidth of rain ranges from tens to hundreds of kilometers, and it is several meters long in Qian Qian. There will be showers and windy weather where the rain belt passes.
