摘要
应用Q矢量分析方法对20次伴有暴雨的江淮梅雨锋过程进行分析,揭露了梅雨锋暴雨期对流层低层Q矢量散度场的分布特征以及与中、低空主要天气系统和暴雨带之间的时空配置关系,指出了Q矢量散度场对江淮梅雨锋暴雨的落区有较好的预报意义。
wenty processes of the Meiyu front with heavy rain over the Changjiang-Huaihe Valley are analysed by using Q divergence. The distribution and characteristics of the Q divergence on the middle and low layers in troposphere in Meiyu front are studied,the space-time relationship between the belt of heavy rain and the main weather system on the middle and low layers in troposphere is also studied. The results show that Q divergence is comparatively reasonable for forecasting of the area of heavy rain on Meiyu front over Changjiang-Huaihe Valley.
