static energies

Measures of the thermodynamic state of the air, similar to potential temperature.

For example, the dry static energy (also known as the Montgomery streamfunction) is
ams2001glos-Se58
where g is acceleration of gravity, z is height above some reference level (often taken as the height where the pressure is 100 kPa), Cp is specific heat at constant pressure, and T is absolute temperature. Typical atmospheric values are on the order of 300 kJ kg-1. Compare this static energy to one definition for potential temperature,
ams2001glos-Se59

See moist static energy, liquid water static energy, saturation static energy.
