The rate of change of temperature by an ascending or descending airmass.

The rate of change of temperature by an ascending or descending airmass. If no other non-adiabatic processes (means no heat enters or leaves system) occur(like condensation, evaporation and radiation), expansion causes the parcel of air to cool at a set rate of 0.98° per 100 m. The opposite occurs when a parcel of air descends in the atmosphere. The air in a descending parcel becomes compressed. Compression causes the temperature within the parcel to increase at a rate of 0.98° per 100 m.
