The crabs in Sansha were blown ashore by the typhoon, and crabs were everywhere. Why is this happening?

Because the appearance of typhoon has brought strong wind and rain influence to Sansha City, crabs live by the sea, so they will be blown ashore by typhoon.

Typhoons usually exist? Three characteristics? : First, the intensity is high and the wind speed is fast; Second, the influence of wind and rain is wide; The third is destructive. According to the different types of disasters, the losses caused by typhoons can be divided into three categories: catastrophic, compensatory and destructive, among which the most important disastrous weather is typhoon disaster. ?

Typhoon Shana approached and crabs were blown to the dock.

On June 5438+1October 65438+1October 9, 2022, the 20th typhoon "Dasha" in China gradually approached the southeast coast of Hainan Island. Typhoon Shana brought strong wind and rain influence through Sansha City, which led to the spectacle of flying crabs in the sky. Many netizens said that this crab never dreamed that it would fly in its lifetime.

Shana? How did it evolve into a typhoon?

It is a strong tropical cyclone developed from tropical disturbance. ? Shana? Its intensity development is influenced by subtropical high edge, low-level jet and ground convergence zone. With the strong water vapor transport around the vortex in the circulation, the typhoon center gradually moves to the northwest; Affected by cold air, when the intensity of the ground convergence zone weakens, Shana? The intensity weakened again and finally dissipated gradually.

How to protect yourself when the typhoon comes?

The arrival of the typhoon did not cause serious disasters, but it brought heavy rainfall and strong winds. As can be seen from Shana's path, the loss caused by the arrival of the typhoon is huge. Therefore, in order to better protect ourselves, we should observe the weather forecast in advance, close the doors and windows, and imprison large objects that are easily blown by the wind to prevent economic losses. Some tropical cyclones have formed in the South China Sea and the Northwest Pacific Ocean, affecting southern China. Most of these cyclones belong to tropical cyclones. However, tropical cyclones have the characteristics of fast moving speed and high intensity, and have obvious regional and seasonal climate characteristics like other atmospheric disasters. ?
