摘要: 对影响华南的西风带系统和热带系统的各类云系闪电时空分布特征进行分析研究, 比较它们之间的异同。结果表明:西风带系统云系的闪电过程在前汛期大部分出现在夜间, 而热带系统云系的闪电过程几乎都出现在日间;西风带系统云系的闪电分布形态特征和范围与热带系统云系有很大的差异。同时对各类云系的闪电成因进行了探讨。

Abstract: The spatial and temporal distribution character for lightning of the westerly zone systems and tropical systems that influence the south of China is studied and analyzed, and the difference between them is compared. The results indicate that in the yearly-first flood season, most of the lightning process of westerly zone systems occur at night, while the counterparts of the tropical system almost always happen in daytime; cloud systems of the westerly zone system are quite different from the tropical system in the lightning distribution character and range. The cause of the formation for lightning is also discussed in this article.
