Abstract
Seasonal variations in the surface heat fluxes and the soil water contents for the four soil types were estimated, with the use of a soil model and the routine meteorological data of 30 stations in China. Tables of the annual mean values of the sensible and latent heat fluxes, annual potential evaporations, annual precipitations, and the soil water contents at the depths of 0.66m and 0.26m on December 31 are presented. It is found that the annual amount of evaporation and the soil water content in dry season depend on the annual amount of precipitation. A geographic distribution of the annual means of sensible and latent heat fluxes is shown. The net radiation, which is the sum of these fluxes, is large in southern China and the Tibetan Plateau region. The sensible heat flux dominates and the latent heat flux is extremely small in desert region. In general, the net radiation for a loamy soil is larger than that for a sandy soil.
