Free Tornadoes SVG Files

Tornado SVG is an atmospheric vortex that appears in a cumulus-rain (thunderstorm) cloud and spreads downwards, often to the very surface of the earth, in the form of a cloudy sleeve or trunk with a diameter of tens or hundreds of meters. The development of a whirlwind from the cloud distinguishes it from some externally similar and also different in nature phenomena, for example, whirlwind whirlwinds and dusty (sandy) whirlwinds. Usually, the cross-section diameter of the funnel of a tornado in the lower section is 300-400 m, although, if the tornado touches the surface of the water, this value can be only 20-30 m, and when passing the funnel over land can reach 1.5-3 km.

Tornado SVG Description

Inside the funnel, the air drops and rises from the outside, rotating quickly. An area of very thin air is created. Determining the air velocity in the funnel is still a serious problem. Estimates of this value are mainly known from indirect observations. Depending on the intensity of the vortex, its current velocity may vary. It is estimated that it exceeds 18 m/s and can, according to some indirect estimates, reach 1300 km/h. The whirlwind itself moves with the cloud that gives rise to it. This movement can produce tens of kilometers per hour, usually 20-60 kilometers per hour. By indirect estimations, the energy of a usual Tornado SVG with a radius of 1 km and an average speed of 70 m/s is comparable to the energy of a reference atomic bomb, similar to that which was blown up in the USA during the tests of “Trinity” in New Mexico on July 16, 1945. The record of time of existence of a Tornado SVG can be considered as Mattun’s tornado which on May 26, 1917 for 7 hours 20 minutes has passed on territory of the USA 500 km, having killed 110 persons. The width of the blurred funnel of this tornado was 0.4-1 km, inside it was visible a whiplash funnel. Another famous case of tornado is the tornado of the Three States (Tristate tornado), which on March 18, 1925 passed through the states of Missouri, Illinois and Indiana, having done the way in 350 km in 3.5 hours. The diameter of his vague funnel ranged from 800 m to 1.6 km. About 700 people died.

A cascade of clouds or pillars of dust, debris, and objects lifted from the ground or water splashes may appear at the point of contact of the base of the whirlwind funnel with the surface of the ground or water. In the formation of a tornado, the observer sees a cascade rising from the ground towards the funnel falling from the sky, which then covers the lower part of the funnel. The term comes from the fact that the debris, having risen to a certain height, can no longer be held by the air stream and fall to the ground. The funnel, not touching the ground, can wrap around the case. By merging, the cascade, the case and the mother’s cloud create the illusion of a wider tornado funnel than it actually is.

Sometimes a whirlwind formed on the sea is called a whirlwind, while on land it is called a tornado. Atmospheric whirlwinds, similar to tornadoes but forming in Europe, are called clots. But more often than not, all three concepts are considered synonyms.
