A tornado hit Kentucky, killing 80 people. What are the causes of tornadoes?

Tornadoes have killed 80 people in Kentucky. The formation process of tornado is: the temperature difference between the upper and lower clouds in the sky is too large, and the hot air rises to form a small upward vortex. Cumulus clouds form cumulonimbus clouds in the vortex, and its latent heat continues to heat up, which will form a powerful airflow, which forms a tornado.

65438+February 1 1 Kentucky suffered from severe natural disasters such as tornadoes and floods. As of 65438+February 13, the death toll in the state has reached 80, but the White House said that according to the situation of the disaster, the death toll will exceed 100. Biden said in America?

The overall disaster situation is very serious, leaving a ruin after the tornado.

In fact, the arrival of the tornado has long been a warning. 65438+February 10, the temperature in the central United States is very abnormal, and the temperature is very warm, unlike the weather in 65438+February. Obviously, high temperature will provide conditions for tornadoes, and cold air convection will form a small vortex, which will gradually produce tornadoes. There will be at least 30 tornadoes in the night of 6 10.

Tornadoes are relatively rare in China. They are common in tropical and warm regions. They need heat to form, and the conditions for formation are difficult to achieve. They generally appear in the inland areas of the United States and Western Australia.

Although it is rare in China, we should pay attention to it. If you encounter this kind of weather, you should choose a strong house or a basement to hide. Never hide in the car, it will be carried away by a tornado.
