摘要:

根据已有文献描述的对球形闪电的观测和研究结果,总结了球形闪电的观测特征,介绍了目前对球形闪电的实验研究和理论研究现状,对球形闪电的结构模型进行了简单概括。还基于云对地的线状闪电,详述了一种形成球形闪电的等离子体模型。在该模型下,在某特定环境下线状闪电等离子体通道的一个区域坍塌成小的区域,形成球形闪电。指出了未来对球形闪电的研究方向。

关键词: 球形闪电, 等离子体, 线状闪电

Abstract:

According to the observation and study of the literature on the ball lightning, the observational characteristics of ball lightning are summarized. Then the theoretical and experimental research status on the ball lightning are introduced, and the model of ball lightning structure is briefly epitomized. Based on linear lightning of the cloud versus earth, a kind of plasma model formed ball lightning is introduced. According to the model, the plasma channel of line lightning collapses into a small region in specific environmental condition, so as to form a ball lightning. The research direction of ball lightning in the future is summed up in the final part of this paper.

Key words: Ball lightning, Plasma, Linear lightning
