Abstract: In this paper, an analysis is presented concerning the thermal characteristics over the Zhangye region of China during the summer of 1984. The mean sensible and latent heat transfer, the drag coefficients of heat and moisture are estimated in this period by using the thermal equilibrium method. In this region, sensible heat flux and heat drag coefficient increase with height, but latent heat flux and moisture drag coefficient decrease with it. The thermal parameter variation indicates a 3—5 day medium–range oscillation period just as the radiant parameter, and the phase difference between the two parameters is very small and their coherences are above 50% mostly. Therefore, the mean values of sensible heat and latent heat transfer in surface layer can be estimated by using the average radiant parameters. It is shown that the mean characteristics of thermal regime in Zhangye region coincide with those got from QXPMEX–79.
