| 摘 要： | 用全球谱模式T42L11对1991年6月底至7月初江淮暴雨的中期过程作敏感性试验。结果表明，在初始场中，当印度洋～孟加拉湾高湿中心附近(100°E以西)的水汽减弱后，江淮雨量减少45%，且东亚夏季风环流减弱。若南海～西太平洋高湿中心附近(100°E以东)的水汽减弱时，则东亚夏季风环流反而加强，雨带移向华北。

| Abstract: | Using a global spectral model T42L11 the sensitivity experiments to a rainstorm process during period of June 26~July 1, 1991 are performed. The results show that if the vapour sources from Indian Ocean to the Bay of Bengal (to the west of 100°E) were strong cut down, East Asia monsoon circulation would be weakened, and Meiyu precipitation be reduced; on the contrary, when the moisture sources from West Pacific to the South China Sea (to the east of 100°E) were decreased, East Asia monsoon circulation would be strengthened, and the rainfall belt would move over to North China. |
