WebFeb 19, 2024 · A positive latent heat flux (Figure 4.3.2. 2) is illustrated with an arrow pointing up away from the surface of the earth. This indicates that the surface is losing energy to the air above. Evaporation is a cooling process for a surface because energy is removed from the water as molecules escape the surface. WebHere, NR denotes the net radiation, H and L v E are the turbulent fluxes of sensible and latent heat, respectively, and G is the ground heat flux.
