| Research Abstract |
Since the soil property and vegetation control the ratio between heat and moisture provided into the atmosphere, it was speculated that the surface conditions may have an influence upon the property of rainfall systems developed over a landmass. To evaluate this influence, a response of clouds to the surface conditions was examined by several numerical experiments with different surface conditions using a cloud-resolving high resolution model. The result of experiments for heavy rainfall cases over the mainland China show that the conditions of an atmospheric boundary layer was modulated according to the change in the evapotranspiration efficiency. The structure of rainfall systems and the rainfall distribution are modulated according to the change in moisture in the lower troposphere.
