| 摘 要： | 该文利用NCEP/NCAR再分析资料对中国东部区域1991年和1994年这两个夏季旱涝典型年的降水状况、水汽输送及收支状况等进行了综合定量对比分析,结果表明:江淮流域夏季旱涝形势的形成更多地取决于流经其上的东西向水汽输送的变化。南亚夏季风强弱的变化对江淮流域的旱涝形成可能具有更为重要的影响。中国东部夏季的偏西水汽输送主要来自西南地区西边界,江淮流域夏季干旱年该地区西边界的水汽输入明显比洪涝年减少,因而在未来的中国东部旱涝预测中要特别重视西南地区西边界的水汽输送状况。

| Abstract: | The characteristics of precipitation,water vapor transports and circumfluence background are analyzed by using the NCEP/NCAR reanalysis data in 1991 and 1994.The analyzed results show the intensity and space-time distribution of the summer precipitation in east China,the characteristics of water vapor transports under the Jiang-huai valley,especially annual change of the east and west water vapor transports,the input and output of the water vapor on the borderline of the China continent,the characteristics of water vapor income and expenses in each area and the annual,monthly change of the western pacific subtropical high.All of these factors effect the drought and flood of the Jiang-huai valley. |
