Liaocheng, Shandong Province suffered a rare tornado, which also caused huge losses. What is the cause of the tornado? There are actually many reasons for the formation of tornadoes, and the formation of tornadoes cannot be predicted in advance like weather forecast, which means there are many reasons to promote the formation of tornadoes. The formation of tornado in Liaocheng, Shandong Province is estimated to be related to the continuous high temperature weather. The continuous high temperature makes the water vapor on the ground transpiration, and then the air flow in the sky is cold and dry, so that the air flow on the ground will rise to form a vortex, which will gradually become larger and form a tornado.

Tornadoes are very harmful, especially in Liaocheng, where tornadoes are more powerful. Some residents' houses were damaged, and some people were hospitalized because of tornadoes, such as trees being blown down and vehicles being damaged. These are countless, mainly because the formation of tornadoes can't be predicted in advance, so we can't take precautions in advance like forecasting rainstorms. The sudden appearance made Liaocheng, Shandong Province unprepared. At present, Liaocheng has tried its best to take rescue action, and the tornado has moved in the direction of Beijing, Tianjin and Hebei.

Most tornadoes are accompanied by thunderstorms, and residents of Beijing, Tianjin and Hebei should pay more attention. Summer itself is prone to extreme weather, so pay more attention when going out. I read a news the other day that a woman in Ningbo, Zhejiang Province was killed on the spot while riding a bicycle. If it is a thunderstorm, you should find a shop or something to hide for a while, because thunderstorms in summer usually come and go quickly, so don't risk outdoor activities.

In the face of extreme weather in nature, our human strength is still too small, such as earthquakes, tsunamis and tornadoes, which are unpredictable. What we can do is to stay calm in times of crisis and protect ourselves as much as possible. Summer is the rainy season, so we try not to go to the mountains. In case of flash floods, we are in danger.
