[1]在太空中观察到的伽马辐射与雷暴中的闪电有关。这些特殊的闪光似乎并不是巨大的、能量充沛的地面闪光，也会产生精灵。对空气中伽马射线衰减的考虑表明，这种闪光可能不会在足够高的高度产生伽马辐射，使其能够逃往太空。高空地闪可能是一个必要的来源，这种闪电在热带地区最为普遍，那里的对流层顶也很高。
[1] Gamma radiation observed in space has been associated with lightning flashes in thunderstorms. These special flashes do not appear to be the large and energetic positive ground flashes that also produce sprites. Considerations of gamma ray attenuation in air indicate that such flashes may not produce gamma radiation at sufficient altitude to enable their escape to space. High-altitude intracloud lightning, most prevalent in the tropics where the tropopause is also high, may be a necessary source.
