| 摘 要： | 对2010年4月21～23日文山州久旱转大雨过程的环流演变及各种物理量场特征进行诊断分析,结果表明:干旱期文山长期维持"西高东低"环流型,环流形势的调整,尤其是中纬度环流形势向"东高西低"转变,是久旱转雨的必要条件。这次过程也与高空冷槽、低涡切变和不稳定层结(能量)的发展等有关。久旱转雨时,各物理量场的分布与该区域降水相关性很好,具有很明显的指示意义。

| Abstract: | Characteristics of the circulation evolution and the physical quantity field of the process from drought to rain in Wenshan during the period of the time from the 21st to the 23rd April,2010.The result show that there is circulation pattern of high in the west and low in the east over Wenshan for a long time during the drought period; the adjustment on large-scale circulation,especially the changing of mid-latitude circulation into the pattern of high in the east and low in the west,is a necessary condition... |
