During the monsoon season, the precipitation variation on the Tibetan Plateau is remarkable because it is strong affected by different dominate synoptic-scale meteorological systems in the middle latitude (Ueno et al., 2001). One is associated with the synoptic-scale front passage of the Plateau (hereafter, referenced as case1) and the other is associated the meso-scale convection on the Plateau (hereafter, referenced as case2). Our purpose in this study is to simulate the different precipitation phenomena@(case1 and case2) with a non-hydrostatic numerical model, and try to make the mechanism clear.
˘y Our simulation results have been compared with the GAME-reanalysis data. For case 1 and 2, geo-potential height and wind at 250 and 500 hPa are consistent well with the GAME-reanalysis data. Furthermore, the calculation results show much more details on the flows than the GAME-reanalysis data could give. Although, the calculated wind velocity is somewhat larger near the Himalayas, it is found that the simulation is quit realistic. Now, date analysis is being carried out, and we will give more results in the presentation.
