- Expanding air cools. Compressing heats.
- Dry Adiabatic lapse rate – rate dry air cools as it rises.
- Wet Adiabatic lapse rate – rate saturated air(cloud) cools as it rises.
- Rising dry air will cool until it meets the dew point. Becoming cloud and then cooling at the wet rate.
- Air will stop rising when it reaches air matching its own temperature.
