| 摘 要： | 本文通过1991年梅雨后期，7月1—13日200hPa非地转场分析得出，梅雨期200hPa非地转风主要由积云对流动量转换形成。其次是风速平流，并通过数值试验得以证明。非地转风形成的高层辐散，可进一步使暴雨增强与维持。另外梅雨期非均匀层结对非地转风及暴雨也有较大的影响。

| Abstract: | Analising the ageostrophic wind on 200hPa level during Meiyu period in July 1 - 13, 1991,it showed that the wind was mostly set up by momentum exchange of cumulus convection, by the wind advection next. It is examined by numerical simulation in this paper. The upper divergences caused by the ageostrophic wind increased and maintained the rain. Otherwise,the heterogeneous stratification was a great factor for the rain and wind during the Meiyu period. |
