The surface energy balance (SEB) determines the amount of energy flux available to evaporate from surface (latent heat flux), exchange of energy between the surface and the atmosphere (sensible heat flux) and between the surface and the subsurface layer (ground heat flux) (soil, rock, water etc.). We have been used the simultaneous heat and water (SHAW) model to determine the surface energy balance and flux. The SHAW model requires the usage of the high precision data. This requirement led us to choose the three station with highly detailed metrological data. The two of them located in the permafrost area (Udleg, Nalaikh), other one located in seasonally frozen ground zone. In this study, we aimed to describe the reasons why two sites has permafrost exist and one none, based on the difference of the variables of SEB. In Udleg site, the highest value of the energy flux was the ground heat flux. It occupied about 60% of the total energy flux. The highest flux value of Terelj site was the sensible heat flux about 70% of amount energy flux. All of three energy fluxes values was almost equal in Nalaikh site.
