Smerch (tornado). Atmospheric vortex in the form of dark sleeves with vertical curved axis and a funnel-shaped extension at the top and bottom parts. The air rotates with a speed of 300 km/h counterclockwise and ascends in a spiral, pulling in a variety of subjects. The air pressure in the tornado is lowered, the height of the arm can reach 1000 -1500 m, the diameter is from several tens of meters above the water to hundreds over land. The length of the path of a tornado varies from several hundred meters to tens of kilometers. The speed of the tornado was 50 - 60 km/h.
A tornado originates in a thunderstorm cloud and falls to the ground (water). This occurs most often in the warm sector of the cyclone before the cold front. The tornado moves in the same direction as the cyclone is accompanied by thunderstorms, rain, hail, sharp wind. The path of the tornado destruction is inevitable by the impact of rushing air, a large pressure difference in the internal and peripheral part of the tornado. Extreme danger tornadoes pose to vessels on the high seas. A tornado can lift high into the air, building, car, person. Contact Twister always ends with injuries or deaths.
Tornadoes occur in all parts of the globe. They mostly occur in the United States, Australia, and northeastern Africa.
Storm. Long lasting, strong wind, moving at a speed of 103 - 120 km/h, causing a large swell on the sea and destruction on the land. The storm is the cause of annual deaths of dozens of ships, less destruction on the coast.
Storm. Wind moving at a speed of 62 — 100 km/h. This wind is able to blow the top layer of soil for hundreds of square kilometers, to move through the air at great distances, millions of tons of fine-grained particles of soil, snow, and desert sand. Storms can cover huge areas of dust, sand, earth and snow, the thickness of the applied layer is tens of centimeters. Destroyed the crops, filled the roads, polluted water bodies and the atmosphere, reduced visibility. Known deaths during the storm people.
During a winter storm in the air rises the huge amount of snow, which leads to heavy snowfalls, blizzards, snow drifts. Snow storms paralyze the traffic, breaking the power supply lead to tragic consequences, wind promotes the cooling of the body, frostbite.
