Tornadoes are whirlpools in the air, which are very destructive. How do tornadoes form?

How is a tornado caused? How destructive is it?

Tornadoes are stronger than strong typhoons, and they are small-scale gas tumbling eddies. Generally speaking, under the very unstable climate standard, it is produced from the strong convection fitness exercise in the air. There is obvious interaction between updraft and tangential wind in each field, and the middle of the cyclone gradually rotates and expands left and right, forming a columnar gas vortex. If the rotation develops, the faster the gas vortex spreads to the ground, the stronger the negative energy pressure on the ground, and the tunnel construction is produced. As a weather system with extreme weather, hurricane is extremely destructive, although its damage range is limited.

Tornado speed is high, and the core low pressure is the cause of great destructive power. The wind is strong, with the wind exceeding 100m/s, and it is more common to exceed 200m per second. The huge wind speed can be said to be invincible. The interaction force can be calculated according to the intensity of exercise. If the mental stress is low, you can smoke by yourself. Generally speaking, in the northern part of China, in autumn, with the collision between strong cold air and subtropical cold and humid airflow going north and south, deep cumulonimbus clouds are generated after vortex movement. If this vortex motion is violent, it may fall from the sky to the ground, forming a trapezoidal cloud column, which is tunnel construction. This tornado has extremely strong wind speed and amazing destructive power.

The whole process of tunnel construction is generally divided into four links: the variability of air causes obvious upward airflow, which is further strengthened by the action of large gas in the rapids. Due to the interaction with the wind whose speed and azimuth change in the vertical direction, the updraft gradually rotates in the middle of the ionosphere and becomes a mesoscale cyclone. With the development trend of mesoscale cyclone to the ground, it widens, narrows and rises by itself. At the same time, the total area of spokes is small, that is, a new tornado is generated inside the cyclone, which is also the key to the tornado in the whole process of causing the cyclone. The rotation of tornadoes in the earth's core is different from that of cyclones, and they have enough compressive strength to widen tornadoes to the ground. After the vortex of the development trend reaches the relative height of the ground, the standard air pressure on the ground drops sharply and the wind force on the ground rises greatly, which leads to tunnel construction.
