Tornado is a vortex in the air, which is very destructive. How is tornado formed?
How is a tornado caused? How destructive is it?
a tornado is stronger than a strong typhoon, and it is a small-scale gas tumbling vortex. Generally speaking, under the very unstable climate standard, it is produced by strong convection fitness exercise from the air. The obvious updraft and cutting winds in various fields interact with each other, and the middle part of the cyclone gradually rotates and expands left and right, resulting in 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 will be, and the tunnel construction will be produced. As a weather system with extreme weather, hurricanes are extremely destructive, although their harm scope is limited.
the tornado speed is high, and the low pressure at the core is the cause of great destructive power. The wind force is larger than 1m/s, more often than 2 m per second. That great wind speed can be said to be invincible. The interaction force can be calculated according to the exercise intensity. If the mental stress is low, you can suck things up by yourself. Generally speaking, in the northern part of China, in autumn, with the collision of strong cold air with subtropical cold and humid air moving northward and southward, deep cumulonimbus clouds are generated after vortex movement. If this vortex exercise is more violent, it may fall from the sky to the ground, resulting in a ladder-shaped cloud column, which is tunnel construction. This tornado has extremely strong wind speed and shocking 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 under the action of gas in rapids. Because of 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 upwards, narrows and lifts itself. At the same time, the small total area of spokes, that is, the newborn tornado is generated inside the cyclone, which is the key to the tornado in the same whole process of causing the cyclone. The rotation of tornado in the core is different from that of cyclone, and it has enough compressive strength to widen tornado 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, resulting in tunnel construction.
