摘　　要：根据卫星、地面、飞机和气球的探测结果,TGFs和与雷暴、闪电过程有关的高能辐射现象可以大致分为2类:持续时间为毫秒量级的短时间高能辐射,一般认为多数可能与闪电有关;持续时间为几秒甚至更长的长时间高能辐射,一般认为可能与雷暴有关。对已有的TGFs和与雷暴、闪电有关的高能辐射现象的观测事实、理论探索和数值模拟方面的进展进行简要的回顾,并提出目前尚未解决的问题。According to the experimental data from satellites,jets and balloons, TGFs and high energy radia- tion relative to thunderstorms and lightning flashes can be classified into two categories： The short-duration events on the order of milliseconds are considered relative to lightning flashes ; the long-duration events on the order of sec- onds or longer are considered relative to thunderstorms. An attempt was made to summarize the available experi- mental data,theoretical study and modeling effort, and some presently unsolved problems at present were outlined.
