Is the typhoon in Huzhou, Zhejiang Province serious?
The gust in Zhejiang coastal waters is 8 ~ 10, with a maximum of 24.5m/s( 10) at Shitang Station in Wenling, Taizhou. Affected by it, the gusts in the northern part of the East China Sea are 9 ~ 1 1, and those in the south-central part of the East China Sea are 13 ~ 15, and the gusts in the nearby sea passing by the typhoon center can reach 16 ~ 17. The maximum gust along the coast of Zhejiang is 8 to 10, and there are also 6 to 8 gusts along the coast. Influenced by the circulation around Kanu.
There are still showers in Huzhou, and the local area may be accompanied by short-term heavy rainfall, and the wind gradually increases to 4-5. The gust of sea surface in Taihu Lake and alpine areas can reach 7, which is easy to cause secondary disasters such as flash floods, landslides and urban and rural waterlogging in small watersheds. Typhoon is not a point, it is a huge circulation system, rotating around extremely high wind speed. Wherever the circulating current goes, it may bring violent storms, blow down houses and trees, wash away river banks and reservoirs, cause floods, interrupt telecommunications and block traffic, with great destructive power.
Causes of typhoon formation
The cause of typhoon formation: On the vast tropical ocean surface where the seawater temperature is higher than 26.5℃, a large amount of seawater evaporates 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. The continuous high temperature makes the tropical cyclone stronger and stronger, and finally forms a typhoon.
When the wind speed reaches 10.8m/s, it is called tropical depression, 17.2m/s is called tropical storm, 24.5m/s is called strong tropical storm, and 32.7m/s is called typhoon. The wind speed of super typhoon can reach more than 50m/s, which is a natural disaster comparable to earthquake.
