Abstract

Abstract

In this paper, the importance of investigation on terrestrical processes in arid areas for mankind's living environment protection and local economics development as well as its present state of the art are elucidated. A coupling model, which evaluates heat, mass, momentum and radiative fluxes in the SPAC system, is developed for simulating microclimate over plant and bare soil. Especially,It is focussed on the details of turbulence transfer. For illustration, numerical simulation of the water-heat exchange processes at Shapotou Observatory, CAS, Ninxia Province are conducted, and the computational results show that the laws of land-surface processes are rather typical in the arid areas.
