Tornado development begins when wind shear, wind blowing in different directions at different altitudes, starts air rolling horizontally. This horizontally rolling air can then get turned vertical by a thunderstorm. The updraft of the storm then starts rotating as a result, becoming a mesocyclone. Under the right conditions a downdraft can wrap around the mesocyclone, tightening and intensifying it to form a tornado.
