摘要
分析 2 0 0 1年 9、1 0月份淮河流域严重干旱的大尺度环流形势背景 ,并与历年出现的旱、涝年份的 50 0hPa环流特征进行了对比分析。结果表明 ,副热带高压持续偏北偏强 。
The large scale circulation of Huaihe river basin drought event in the autumn of 2001 is analyzed, and further,the circulation features at 500hPa in flood/drought years are comparatively studied.It is shown that the west Pacific subtropical high is located more north,and its west ridge and stretches more west than the mean, which are main causes of Huaihe basin drought event in the autumn,2001.
