Rising Expanding
Sinking Contracting
As a saturated
parcel rises and expands, the release of latent
heat mitigates the adiabatic
cooling
Cooling for saturated air varies with mixing ratio.
We will use an average value of 6oC/km for moisture lapse rate
Note: sinking air always warms at dry lapse rate
