雷击火形成的确定性因素研究

Study on Certain Factors Contributing to the Formation of Lightening Fires

借鉴国内外学者有关雷电物理的研究成果应用于雷击火现象的理论分析和探讨,以闪电能量为主导因素,从积雨云起电、闪电的云-地连接、地面回击参量和闪电的物理效应等方面,阐述闪电与林木的连接过程和引燃林火的物理机制。

Based on the practice of domestic and foreign scholars using the research findings of thunderbolt physics for the theoretical analysis and discussion of lightening fire phenomenon and with the lightening energy as the leading factor, the connecting process of lightening and trees and the physical mechanism of igniting forest fires are stated in term＇s of charging in cumulonimbus clouds, cloud-ground connection of lightening, ground return stroke parameters and physical effects of lightening.
