Then when the cold air sharply bumping on the ground, and rises in the form of warm air. The vortex has a vertical (or slightly inclined to the horizontal) axis of rotation, the height of the vortex is usually 10-20 m (in some cases several tens of meters), diameter of 1-5 m, the time existence – from several seconds to 1-2 minutes. The vortex lifts from the surface of the earth dust, sand, pebbles, small objects and transfers them sometimes at a considerable distance (hundreds of meters). Vortices are narrow band, so directly on the weather station wind may be weak, but actually inside the vortex the wind speed is 8-10 m/s and more. Horizontal visibility at 2 m is 10 km or more.
