Notes:

(1) Total (atmospheric) energy is the sum of internal energy, potential energy, kinetic energy and latent heat. Same applies to energy fluxes.

(2) The water enthalpy (flux) is the enthalpy (flux) associated with the temperature of the water mass.

(3) The water potential energy flux is the flux of potential energy associated with the water mass.
