Tornadoes

Tornado is a violently rotating column of air in contact with the ground. It usually forms under a cumulonimbus (thunderstorm) cloud and is visible as a condensation funnel or by the dust and other debris incorporated into the rotation (Schultz and Cecil, 2009). About 1,500 tornadoes are recorded annually around the middle latitudes of Earth, and they typically cause 100 to 300 deaths.

Tornadoes occur in many regions of the world but are most frequent in the middle latitudes. The United States records about 1,100 tornadoes annually. Tornadoes are under counted in many countries because small tornadoes are not observed and recorded. ...
