How Do They Form?
It usually starts with a supercell which all starts a severe thunderstorm. Soon warm, moist air meets with cold, dry air by rising up, because it is less dense, in an updraft which is like a fast current. Soon the wind increases in speed up to 300 mph and an increase in height to create a funnel cloud which makes tornado.
