Tornadoes form can be varied - column , cone, glass , barrel, bichepodobnaya rope hourglass horns "devil" and the like, but most often , tornadoes have shaped rotating trunk , tube or funnel hanging from the parent cloud . Typically, transverse diameter of the funnel of a tornado in the lower section is 300-400 m, although if a tornado touches the surface of the water , this value may be only 20-30 m, and the passage of the funnel over land may reach 1.5-3 km.
