| 摘 要： | 针对陇南出现暴雨最多的环流形势1],对8次暴雨过程的数值预报产品资料进行合成平均,求出平均场,分析了Q矢量散度、螺旋度、假相当位温、Q矢量地转锋生函数、湿位涡和锋生函数等物理量场,这些物理量场不仅能很好揭示陇南暴雨形成的机制,同时对暴雨落区预报也有很好的指示意义。

| Abstract: | Based on the circulation pattern occurring rainstorms most frequently in Longnan region of Gansu province,the mean fields of numerical prediction products of eight rainstorm cases were calculated,and the physical quantity fields were analyzed such as the divergence of Q vector,helicity,pseudo-equivalent potential temperature,frontogenesis function of Q vector,and moist potential vorticity(MPV),etc.Results show these physical quantity fields can not only reveal the rainstorm formation causes well,but also have some indications to rainstorm area forecast. |
