Equivalent temperature is the temperature of an air parcel from which we would have completely extracted its water vapor content by an adiabatic process.
Additional recommended knowledge
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.
