Typhoon Fireworks will land on the coast of Fujian from Zhejiang. How is a typhoon formed?

In recent days, the floods in Henan have worried people all over the country. In the face of disaster, the people of China are united to fight the flood. Other neighboring provinces also sent rescue officers and soldiers, and major companies and actors also organized donation activities. The main cause of this natural disaster is the influence of typhoon fireworks, which is the report of relevant meteorologists. Typhoon fireworks will land on the coast of Zhejiang or Fujian. Let's take a look at how typhoons form in Bian Xiao.

I. Natural disasters

The rainstorm in Zhengzhou was mainly due to the typhoon blowing inland from the coast, which brought too much water vapor, while the terrain near Henan was uplifted and there was a large area of precipitation on the windward slope. After the typhoon landed in Fujian, Zhejiang Province, the rainfall in Henan Province decreased, and this large-scale rainfall was the largest in Zhengzhou for decades, which not only brought profound disasters to Zhengzhou people, but also caused huge economic losses to Henan people. Facing the disaster, the government made a decisive decision.

Second, the formation of typhoons.

The main reason for typhoon formation is that tropical cyclones are formed under the influence of temperature. There are often some weak eddies on the sea surface of the Pacific Ocean. These are eye typhoons after the formation of typhoons, which developed from such small eddies. It can be seen from meteorological satellites that there are a large number of tropical eddies on the sunny side, and only a few of them can develop into typhoons. A typhoon needs a wide enough ocean surface, which not only requires the temperature of seawater to be higher than 20 degrees, but also requires the seawater to be deep.

Third, typhoon hazards.

In the process of typhoon formation, the position of typhoon eye changes constantly. A typhoon needs energy. The energy of typhoon comes from the water vapor on the ocean and is influenced by the air. The condensation of water vapor releases huge heat energy, which is an important factor to maintain typhoon in the updraft. To make the typhoon move from the Pacific Ocean to Chinese mainland, there must be enough deviation of the earth's rotation.
