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

where g is acceleration of gravity, z is height above some reference level (often taken as the height where the pressure is 100 kPa), C_p 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,
