| 摘 要： | 利用NCEP/NCAR再分析资料对1994、1998年这2个典型旱涝年江淮流域水汽输送及收支状况等进行了诊断分析。结果表明,干旱年该地区主要为南北向水汽输送所控制,而洪涝年江淮流域上空有较强的东西向输送。干旱年5～8月由西、南边界的水汽输入明显比洪涝年少,是造成该地区旱涝的重要原因,因而在未来的江淮流域旱涝预测中要特别重视西、南边界的水汽输送。 |

| Abstract: | The water vapor transports and income and expenses were analyzed by using the NECEP/NCAR reanalysis data in 1994 and 1998. The results showed that Jianghuai basin is mainly controlled by moisture transport from north to south in drought and by the east-west transportation strong in flood. The dry summer from the west,the south boundary of water vapor input was significantly fewer than the flood,which is caused by droughts and floods in the Jianghuai basin. Flood and drought prediction of the Jianghuai basin should pay special attention to the west,the south boundary of water vapor in the future. |
| Keywords: | Atmospheric water vapor transport Atmospheric water vapor income and expense Drought and flood change Jianghuai basin |
