WebIf dry air rises, it cools at a rate of 1°C/100 m. This is the dry adiabatic lapse rate. By adding moisture, this rate changes to 0.6°C/100 m. This is the moist adiabatic lapse rate. The high specific heat of the water is the reason for the difference in the rates. When air at the surface is heated, it rises upward. WebAssuming that air is an ideal gas, this gives a pressure profile is. P ( h) P 0 = ( T ( h) T 0) n. and the density profile is. ρ ( h) ρ 0 = ( T ( h) T 0) n − 1. .
