The Effects of Vertical Distribution of the LowerLevel Flow on Precipitation Location

SUN Ji-song (Beijing Urban Meteorological Institute, China Meteorological Administration, Beijing 100089, China)  
The dynamical effects of the topography on air flows with different vertical distributing have been studied. If a mountain is upright to air flow, the results are as follows: When lower level wind is stronger than upper wind, the divergence motion and wind shear come into being, and eddy will be enhanced, so the precipitation obviously amplitudes against to windward slope. To leeward slope, the situation is opposite. However, when upper wind is stronger than lower, there will be diverged motion on windward slope and eddy will be enhanced on leeward slope. The viewpoints are successfully utilized to explain the different precipitation distributing which happened in North China.
