Wet-bulb potential temperature
Encyclopedia
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.
Temperature
Temperature is a physical property of matter that quantitatively expresses the common notions of hot and cold. Objects of low temperature are cold, while various degrees of higher temperatures are referred to as warm or hot...

Dew point
The dew point is the temperature to which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into liquid water. The condensed water is called dew when it forms on a solid surface. The dew point is a saturation temperature.The dew point is...

Lapse rate
The lapse rate is defined as the rate of decrease with height for an atmospheric variable. The variable involved is temperature unless specified otherwise. The terminology arises from the word lapse in the sense of a decrease or decline; thus, the lapse rate is the rate of decrease with height and...
