中文摘要: 分析和探讨了1996年云南主汛期（6～8月）逐日Q矢量湿锋生函数、Q矢量散度、涡散场能量转换函数、水汽通量散度等4个物理量参数与云南大雨过程的关系，并在此基础上建立了未来24小时大雨预报方程。

Abstract:The relationships between the parameters of Q vector frontogenetical function, Q vector divergence, kinetic energy conversion function and divergence of moisture flux and heavy rain were analysed during the flood season (June to August) of Yunnan in 1996. Based on the analysis results, a forecast equation of heavy rain was established.
