摘要

利用无狭缝摄谱仪获得的云对地闪电回击过程的光谱, 结合同步辐射电场变化资料, 计算了闪电放电通道的温度、线电荷密度、通道的初始半径和扩张后的半径以及回击通道单位长度储存的能量. 结果与文献报道的其他方法得到的结果符合很好. 这些物理量的相关性分析表明: 电弧通道的初始半径主要取决于回击电流的持续时间; 通道温度越高, 半径越大; 通道初始半径、单位长度储存的能量与光谱总强度正相关, 通道单位长度储存的能量与初始半径的平方成正比.

Abstract

Combining the spectra of could-to-ground lightning discharge processes obtained by a slit-less spectrograph with the synchronous electrical information, the temperature, the linear charge density, the channels initial radius, the final radius and the energy per unit length are calculated. The results of these parameters are in agreement with the values reported in other work. The correlative analysis indicates that the arc initial radius mainly depends on the duration of the discharge current, the radius increases with temperature rising, and the total intensity of spectra is correlated positively with initial radius and energy per unit length. The energy per unit length is directly proportional to the square of initial radius.
