关于地闪的几何形态和初始相位
About Geometry and Initial Phase of Cloud-to-Ground Lightning
摘要：
云地闪电是大气放电中最常见的。由于雷云附近的电场不超过250千伏/米，触发闪电的物理过程仍然无法解释。[1，2，3]最近的测量结果表明，太阳风与闪电的发生率之间存在微弱的相关性。[4]在这里，我们表明，如果由宇宙射线产生的电离路径提供了一个触发器，在闪电通道（节点间）中的两个连续分叉点之间的长度分布非常类似于指数分布，平均长度在415 m和510 m之间。这些结果如果得到证实，意味着雷池可能是引发闪电过程的快速基本粒子的另一个来源。
英文摘要：
Cloud-to-ground lightning is the most common among atmospheric discharges. Since electric fields in the vicinity of a thunder-cloud do not exceed 250 kV/m the physical process that triggers the lightning remains unexplained. [1, 2, 3] Recent measurements established a weak correlation between solar wind and incidence of lightning. [4] Here we show, that if an ionized path created by cosmic rays provides a trigger, the distribution of lengths between two successive forking points in a lightning channel (internodes) closely resembles the exponential distribution with average length between 415 m and 510 m. The results, if confirmed, imply that a thunder-cell may be an additional source of fast elementary particles that initiate lightning process.
