闪电先导传输过程中通道温度的变化
Variation of the channel temperaturein the transmission of lightning leader
摘要
Abstract
According to the time-resolved spectra of lightning stepped leader and dart leader processes,the channel temperature as well as its evolution characteristics with time and along the channel in the transmission process of leader have been analyzed.The results show that the temperature of the leader tip is slightly higher than that of the trailing end,which should due to a large amount of electric charge on the leader tip.In addition,both the temperature and the brightness are enhanced on the position of the channel node.The channel temperature of dart leader is higher than that of the stepped leader but lower than that of the return stroke.Meanwhile,the channel temperature of the dart leader slightly increases when the dart leader propagates to the ground.关键词
