利用闪电资料分析冷锋过程的中小尺度系统

Analyses on the meso (micro)-scale systems during the process of cold front using the data of lightning

本文利用京津冀中尺度气象试验基地的资料,分析了1989年8月10日冷锋降水个例,对冷锋影响下闪电活动的特点,特别是其中的中小尺度特征进行了细致的分析和研究,探讨了用闪电资料分析中小尺度系统的方法及可能性。结果表明,利用闪电集中出现的活动带(区)的变化,可以分析冷锋过程中的中小尺度系统及演变。

In this paper, a case of the cold front precipitation is analysed using the data from the Beijing-Tianjin-Hebei Mesoscale Meteorological Experiment. The characteristics of the lightning activity affected by thecold front, especilly, the features of the meso (micro)-scale systems are analysed and studied.The method and the possibility to analyse the meso (micro) -scale systems using the data of lightning is approached. The results show that the meso (micro) -scale systems and their evolution can be analysed according to the variation of the active band (zone) where lightning occured frequently.
