When air rises, moist air cools at a lower rate than dry air.

Dry air does not have as much water vapor, therefore dry air cools at a higher rate with vertical movement than moist air.

This makes moist air generally less stable than dry air (see convective available potential energy).

That is, for the same vertical movement, a parcel of moist air will be warmer than a parcel of dry air.

Moist air has more water vapor than dry air, so more latent heat is released into the parcel of moist air as it rises.
