摘要
雷电发生的时空随机性和瞬时性,以及森林干旱状况、可燃物状况及地形所构成雷击火发生的火环境对闪电、放电引燃林木物理过程的影响非常复杂,导致观测试验和理论研究十分困难。从与引发雷击火密切相关的雷暴和闪电的形成机理,闪电活动与强对流天气过程、雷电预警预报研究、雷电物理过程研究和雷暴起电、放电数值模式研究等6个方面综述森林防雷电研究的成果和近期的研究进展。
The complexity of the influence of chaotic and instantaneous characters, the fire environment contributing to lightening caused fire formed by dry conditions of forest, combustible material condition and terrain on the physical process of lightening and discharges igniting forest trees makes observation tests and theoretical research extremely difficult. The forest lightening prevention research result and recent research development are reviewed in terms of the formation mechanism of thunderstorm and lightening closely linked to lightening caused fire, lightening activity, strong convective weather, lightening forecasting and warning research, physical process study of lightening and thunderstorm charging and discharging numerical mode research.
