Wet-bulb potential temperature
Wet-bulb potential temperature, sometimes referred to as pseudo wet-bulb potential temperature, is the temperature attained by mass of air brought adiabatically to saturation and then carried along moist-adiabat to 1000 mb (hPa).
This temperature is conservative with respect to reversible adiabatic changes.
