摘　　要：对南盘江流域暴雨过程的水汽条件进行了诊断分析．通过流场形势分析出南盘江流域暴雨的水汽主要来自于南海、孟加拉湾和流域当地．对一些暴雨个例进行的水汽通量散度的计算分析表明，南盘江流域的暴雨区一般都落在最大水汽通量辐合中心附近．对于一些扰动系统不太强的一般大雨、暴雨过程，不仅水汽通量辐合持续时间不长，而且强度不大；而对于大暴雨过程，则不但水汽通量辐合持续时间较长。In this paper,the water vapour and it's flux divergence during the heavy rainfall processes over the base of Nanpanjiang rive are computed.The results are as follows:(1)The water vapour that influence the heavy rainfall over the base of Nanpanjiang river comes mainly from the Bay of Bengal, the South China Sea and the local areal(2)The convergence of water vapor flux plays an important role in the strengthening and maintenance of heavy rainfall.
