How Do Clouds Form? 1. Warm, humid air near the ground is heated. 2. The Warm Air rises. 3. The air cools as it rises. 4. The temp. of the air reaches the dewpoint temp. 5. The water changes from a gas to liquid water.
DEWPOINT!!! Dewpoint temperature always has to be the same or less than the air temperature. What do we see when the air temp and dewpoint are the same at ground level?
