Inside the air funnel is lowered, and the outside rises, spinning rapidly, the region created a highly rarefied air. The vacuum is so significant that the closed gas-filled items, including buildings, may explode from the inside due to the pressure difference. This phenomenon increases the destruction of the tornado, difficult to determine the parameters in it. Determination of velocity of the air in the funnel is still a serious problem. In general evaluation of this magnitude are known from indirect observations. Depending on the intensity of the vortex flow velocity can be varied in it. It is believed that it is greater than 18 m / s and may, in some indirect estimates, up to 1,300 km / h. Sam tornado moves with it generating a cloud. This movement speed may produce tens of km / h, typically 20-60 km / h. According to indirect estimates, the energy of a conventional tornado radius of 1 km and an average speed of 70 m / s comparable to the energy of the reference of the atomic bomb, like the one that blew up in the United States during the test, "Trinity" in New Mexico on July 16, 1945. The record time of the existence of a tornado can be Mettunsky considered a tornado, which is May 26, 1917 7 hours 20 minutes was on the US territory of 500 km, killing 110 people. Width vague funnel of the tornado was 0.4-1 km, inside it was bichepodobnaya crater is visible. Another famous case of a tornado is a tornado Three States (Tristate tornado), which is March 18, 1925 has passed through the states of Missouri, Illinois and Indiana, worked his way to 350 km in 3.5 hours. The diameter of its vague funnel ranged from 800 m to 1.6 km.
