liquid water static energy

A thermodynamic variable (analogous to liquid water potential temperature) calculated by first evaporating any liquid water present in the air, and then lowering it adiabatically to a reference altitude z often taken either as the local surface (z = 0), or as the altitude where the ambient pressure is 100 kPa:
where g is gravitational acceleration, Lv is the latent heat of vaporization, Cp is the specific heat at constant pressure for air, T is absolute temperature, and rL is the liquid water mixing ratio in the air.
