What Is The Dry Adiabatic Lapse?

What Is The Dry Adiabatic Lapse? Dry-adiabatic lapse rate. A process lapse rate of temperature, the rate of decrease of temperature with height of a parcel of dry air lifted by a reversible adiabatic process through an atmosphere in hydrostatic equilibrium. What is a dry adiabatic lapse rate? The rate at which dry (i.e. unsaturated)
