| 摘 要： | 利用WRF模式中提供的不同平滑地形方案对2007年5月30-31日发生在湖北西部地区的暴雨过程进行数值模拟。在此基础上，利用WRF模式进行地形高度敏感性试验。结果表明：地形平滑方案与降水的时空分布有很大的相关性，地形越接近实际地形，降水的时空分布越接近实况；地形高度对降水的强度及落区影响较大，随着山脉地形高度的增加，迎风坡和背风坡的2个降水中心带有远离山脉的趋势，当山脉高度达到一定高度以后，迎风坡和背风坡的两个降水中心带又有靠近山脉的趋势。

| Abstract: | Based on the different terrain smooth schemes in the weather research and forecast(WRF) model,the numerical simulation of rainstorm process from 30 to 31,May 2007 in western Hubei province was carried through.And the sensitivity of terrain height was analyzed by WRF model.The results indicate that the terrain smooth schemes with the temporal and spatial distributions of precipitation are related.The closer the terrain is to the actual situation,the closer the temporal and spatial distributions of precipitation are to the actual situation.The terrain height can influence the intensity and falling area of precipitation.The two precipitation centers of windward slope and leeward slope tend to be far away from mountain with the terrain height increase of mountain,and they tend to be close to the mountain after the terrain height reaches the certain height. |
