补充资料:直击雷
分子式:
CAS号:

性质:带电积云与地面目标之间的强烈放电称为直击雷。带电积云接近地面时,在地面凸出物顶部感应出异性电荷,其间电场强度增大。当积云与地面凸出物之间的电场强度达到25~30kV/cm时,即发生由带电积云向大地发展的跳跃式先导放电,持续时间约为5~10ms。当先导放电达到地面凸出物时,即发生从地面凸出物向积云发展的极明亮的主放电,其放电时间仅50~100μs。主放电向上发展至云端即告结束。主放电结束后继续有微弱的余光,持续时间约为30~150ms。大约50%的直击雷有重复放电的性质。平均每次雷击有三四个冲击,最多能出现数十个冲击。第一个冲击的先导放电是跳跃式先导放电,第二个以后的先导放电是放电时间仅为1ms箭形先导放电。一次雷击的全部放电时间一般不超过500ms。其防护措施参见直击雷防护。
