Air contains water vapor that has been evaporated into it from liquid sources (lakes, sea, etc...). The energy needed to do that has been taken from the air. Taking a volume of air at temperature T and mixing ratio of r , drying it by condensation will restitute energy to the airmass. This will depend on the latent heat release as:
: specific heat at constant pressure for air ( 1004 J/(kg·K))
Tables exist for exact values of the last two coefficients.
