This is even the case up to a small distance away from the tornado. Debri can be taken to huge heights and dumped hundreds of metres around the tornado path. Tornadoes occur from large, very severe thunderstorms. The largest type of thunderstorm on earth is known as the supercell. Due to the overall rotating structure of supercells, they are responsible for most of the reported tornadoes as well as the most violent.
Tornadoes can also occur in other severe thunderstorms known as multicells.
Severe multicells differ in their structure from supercells in that they are normally not associated with a rotating structure. Multicell structure involves the development of newer adjacent cells as other cells die. Tornadoes that occur will normally develop in the mature or developing cells. Although the dynamics of tornadic development are very complex, the visible features of tornadoes are generally similar. MOST tornadoes develop from lowered rotating bases known as wall clouds.
