Tornadoes are started when wind shear starts air masses rolling in what is called horizontal vorticity. This rolling air movement can be turned vertical by the updraft of a thunderstorm, which then takes on the rotation to become a mesocyclone. Under the right conditions a downdraft can descend from the back of the storm and wrap around the mesocyclone. This can tighten and intensify the rotation and br9ing it down to the ground to produce a tornado.
