| Abstract: | In order to investigate the of city effects meso-scale on heavy rain, a three-dimensional model is used to simulate the effects of the underlying surfaces on the cyclnic precipitation process. The expri-ment howes that non-liomogeneous influence of underlying surface is exited in the local thermal and dynamical structure of the PBL and corresponding circulation. Therefore, the change of the instability stratification, wind and veryical circulation and the influence of rainfall location are analysed. |
