Given enough moisture, when unsaturated air is lifted upward, it expands and cools at the DALR and clouds may form.
A super-adiabatic lapse (right) is a lapse rate that exceeds the DALR and appears as a "foot" at the bottom of the temperature line.
This rate is typically less than the DALR because as the saturated air cools, water vapor condenses and releases latent heat back into the parcel--it warms up the parcel--effectively slowing down the cooling process.
