WebSources of Lift (upward) Typically, for a thunderstorm to develop, there needs to be a mechanism which initiates the upward motion, something that will give the air a nudge upward. This upward nudge is a direct result of air density. Some of the sun's heating of the earth's surface is transferred to the air which, in turn, creates different air ...
