Tornadoes
Tornadoes occur in most parts of the world. However they are most frequent over the continental plains of the USA.

Tornadoes are typically identified as a funnel of spiraling air descending from the base of clouds to the earth. The tornado is usually narrow, about 1/2 km wide and rarely does it move more than 20 km.

Like hurricanes the precise mechanism of how the funnel forms in not understood.

Hurricane
Tropical Storms start within 8º and 15º north and south of the equator where surface sea temperatures reach 27ºC. The air above the warm sea is heated and rises. This causes low pressure.

The weather system generates heat which powers the storm, causing wind speeds to increase. This causes the Tropical Storm to sustain itself. Tropical storms rely on plenty of warm, moist air from the sea - this is why they die out over land.
