The influence of land surface on atmosphere

The mathematical model of land surface consisting of the layer of vegetation and the upper layer of soil is described. The scheme of land surface-atmosphere interaction is based on the transformation of heat and moisture fluxes which allows the use of a small number of parameters. The model is coupled with Global Climate model of the Computing Center of the Russian Academy of Sciences. The results of test investigations using $5^\circ\times 4^\circ$ и $1^\circ\times 1^\circ$ latitude-longitude grid resolution are compared.
