As masses of warm, moist air are hurled upward to meet the colder air above, the moisture condenses and builds into raindrops heavy enough to fall downward through the updraft. When this precipitation is heavy enough, it can reverse the updraft. Between these downdrafts (shafts of rain), updrafts continue at tremendous velocities. It is not surprising, therefore, that the areas of maximum turbulence are near these interfaces between updraft and downdraft. Keep these facts in mind when tempted to crowd a rain shaft or to fly over an innocent- looking cumulus cloud.
