Numerical Simulation Tests of the Meso-scale System for the North of Shaanxi Province

Three cases are chosen to verify the MM5V3.5 model′s simulating capability for meso-scale system in the north of Shaanxi province. The results indicate that at 9km resolution and NCEP as the large scale background field, the model has the best ability of simulating the pattern of summer rainfall and evolution features except some deviation in the position and intensity of precipitation centers. Also, it has higher capability of imitating the trend of winter temperature. Meanwhile, it is poor of its performance in simulating the extreme local precipitation centers, and, there appear some dummy rainfall centers in precipitation′s simulation for large areas.
