초록

An one dimensional atmosphere-vegetation interaction model is developed to discuss of the effect of vegetation on heat flux in mesoscale planetary boundary layer. The canopy model was a coupled system of three balance equations of energy, moisture at ground surface and energy state of canopy with three independent variables of T_f(foliage temperature), T_g(ground temperature) and q_g(ground specific humidity). The model was verified by comparative study with OSU1D(Oregon State University One Dimensional Model) proved in HYPEX-MOBHLY experiment. As the result, both vegetation and soil characteristics can be emphasized as an important factor in the analysis of heat flux in the boundary layer. From the numerical experiments, following heat flux characteristics are cleary founded simulation. The larger shielding factor(vegetation) increase of T_f while decrease T_g because vegetation cut solar radiation to ground. Vegetation, the increase of roughness and resistance, increase (f sensible heat flux in foliage while decrease the latent heat flux in the foliage.
