Knowing that warm air is lighter and less darksome than cold air, we know that the heated air rises, then cools in the end forming clouds. The wind pushes the clouds over the land. As this happens, grinding with the ground, which is greater than the friction between the lake?s water and the moving air, slows the winds. This causes the air that is carrying the clouds to ? smokestack up?. Meteorologists refer to this as convergence.
Occasionally lake effect snow clouds can develop teeming up and down interrogative to create ?thundersnow?. Thundersnow is a snow storm with thunder and lightening.
