Background technique

Tornadoes are a natural phenomenon, often accompanied by thunderclouds. Usually, a tornado consists of a wind eye and a wind eye wall at the periphery of the wind eye. The wind eye wall is composed of a spiraling upward airflow, which is attracted by the extremely reduced air pressure at the center of the tornado, and the airflow is drawn into the bottom of the wind eye wall from all directions. And then it becomes a vortex around the axis, the air in the wind eye is less, and the air pressure is relatively low, so the wind speed near the wind eye is extremely large, and the destructive force is stronger.

Although the tornado has a small range of influence, its destructive power is extremely great. It often causes crops and tens of thousands of fruit trees to be destroyed in an instant, causing traffic disruption, housing collapse, loss of human and animal life, and where tornadoes often occur. The phenomenon of big trees, smashing vehicles, destroying buildings, etc., sometimes sucks people away, and the damage is very serious.
