从雷暴中检测到两种类型的高能事件。一种是“地面伽马射线闪光”（TGFs），亚毫秒级的辐射与闪电放电同时发生。另一种是持续时间分钟的“伽马射线发光”。虽然这两种现象都被认为起源于强电场中的相对论性逃逸电子雪崩，但它们之间的联系还没有得到很好的理解。在这里，我们报告明确的同时检测到的伽马射线辉光终止和向下的TGF，从地面观察。在2018年1月9日日本的一场冬季雷暴中，我们的探测器捕捉到了伽马射线辉光，它随着环境风移动了大约100秒，然后突然停止了闪电放电。与此同时，探测器观察到由向下的TGF触发的光核反应，其无线电脉冲位于距离辉光停止处约1公里的范围内。这表明，产生辉光的高度带电区域与向下的TGF的启动有关。
Two types of high-energy events have been detected from thunderstorms. One is “terrestrial gamma-ray flashes” (TGFs), sub-millisecond emissions coinciding with lightning discharges. The other is minute-lasting “gamma-ray glows”. Although both phenomena are thought to originate from relativistic runaway electron avalanches in strong electric fields, the connection between them is not well understood. Here we report unequivocal simultaneous detection of a gamma-ray glow termination and a downward TGF, observed from the ground. During a winter thunderstorm in Japan on 9 January 2018, our detectors caught a gamma-ray glow, which moved for ~100 s with ambient wind, and then abruptly ceased with a lightning discharge. Simultaneously, the detectors observed photonuclear reactions triggered by a downward TGF, whose radio pulse was located within ~1 km from where the glow ceased. It is suggested that the highly-electrified region producing the glow was related to the initiation of the downward TGF.
