摘　　要：：具体分析了本文Ⅱ的模拟试验结果。结果表明，该试验较清楚地再现了青藏高原地形对西风气流的影响，也显示了不同地形、急流的有无、强度和位置以及初始槽强度和基本气流斜压性的强度对东移槽的影响。这些结果有的清楚地再现了过去熟知的或还不很清楚的地形影响事实，有的可为东移槽的预报提供着眼点。In this paper, the simulations results of the second part of the series pa- pers are analysed concretely. The results show the experiments reproduce clearly the in- fluence of Qinghai-Xizang Plateau on the westerly flow. The influences of different orogaphy, intensity and location of Jet, intensity of the eastward moving trough (EMT) itself and the baroclinic intensity of the basic westerly on the EMT are showed as well. Some of these results reproduce clearly the well-known facts of the terrain impacts in the past, some of them are new,and some of them can provide reference in the EMT predic- tion.
