| 摘 要： | 应用Q矢量理论对1998年广西6月16～26日连续性暴雨过程进行诊断分析,共分析了11个时次的850 hPa Q矢量散度、锋生函数等诊断场,揭示了广西“98.6”连续性暴雨期间Q矢量散度场和锋生函数场的分布特征,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Q矢量散度场对广西“98.6”暴雨落区有较好的对应关系。

| Abstract: | This article diagnoses and analyzes the continuous torrential rain happened on June 16~26,1998 in Guangxi by adopting Q vector theory. Diagnosis fields such as 850 hPaQ-vector divergence and frontgenesis function in 11 torrential rain cases are analyzed, disclosing the distribution characteristics of Q-vector divergence field and frontgenesis function field, as well as the space-time relationship between the main weather system on the middle and low layers in troposphere and belt of torrential rain. The result shows that there is relatively corresponding relationship between Q divergence field and the "98 6"falling area of torrential rain in Guangxi. |
