中文摘要: 对2002年6月21-23日发生在黄海-长江流域梅雨锋上的一系列由中尺度对流系统(MCS)引起的强对流天气过程进行了云顶辐射亮温(TBB)和天气形势、气象要素等的诊断分析。结果表明:梅雨锋上的MCS是造成这次长江流域产生暴雨甚至大暴雨级强降水的主要系统;MCS的强降水中心(区)与TBB≤-32℃的频率FM、TBB≤-52℃的频率Fs
Abstract:Based on cloud-top brightness temperature data and circulation background, and the physical quantities, Diagnosis of severe convection weather caused by MCS in Mei-yii front over the Yellow Sea-Changjiang River during June 21 to 23, 2002 is made. The results show that the MCS is main system of the heavy rainfall in Mei-yufront over Changjiang River Basin. There is close relationship between the heavy rainfall center and the high occurrence frequency center of convection and deep convection. The frequency of FM(TBB≤-32℃)and FS (TBB≤52℃) can reflect the characteristics of rainfall well and better than the low value center of TBB. In addition, the severe heavy rainfall was caused by the interaction among Mei-yu front, lower level shear line and upper level Tibet high.
