Static energies

From Glossary of Meteorology



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.
