摘    要:利用NCEP再分析资料,引人基于拉格朗日方法的气流轨迹模式(HYSPLITv4.9),将2007年6月19日~7月26日期间淮河流域强降雨分为三个阶段,分析不同阶段水汽输送轨迹、主要通道及其不同源地的水汽贡献.结果表明,影响此次强降水过程的水汽通道主要有三支:一支是西太平洋上副高边缘东南气流输送,另一支是南海南部越赤道...

关 键 词:淮河流域  水汽输送  水汽收支  拉格朗日轨迹

Abstract:By using the NCAR/NCEP reanalysis data and the HYSPLITv4.9 mode,the variation features of the water vapor transportation and the contribution of vapor for major passages are analyzed during the heavy precipitation over the Huaihe River basin from 19 June to 26 July in 2007 which is divided into three stages.The results show that there are three major vapor inflow corridors to the Huaihe River basin.One of them is the southeast flow around the western Pacific subtropical high,another is northward vapor trans...
Keywords:Huaihe River basin  vapor transportation  water vapor budget  Lagrange trajectory
