Popis:	This paper examines the computation of surface-level vertical fluxes of total energy in a moist atmosphere. A flux equation is derived which includes the enthalpy of water, the temperature dependence of the latent heat of condensation and variable moisture composition of air. The complete formulation requires keeping track of liquid water fluxes. However, if this is not possible, then the total energy flux is best approximated by neglecting the enthalpy of all net fluxes of water substance. An important finding is that sensible heat fluxes derived using a moist specific heat at constant pressure are not compatible with usual formulations of latent heat unless the net vapor flux is neglected.
