I had heard that thunderstorms generate gamma rays before, but I assumed those were produced by the lightning. Apparently I assumed wrong and it might actually be the other way around. Very interesting.

I was involved in atmospheric physics about 30 years ago and back then there were two competing theories for thunderstorm electrification, neither of which made complete sense. My understanding is that it is still like that today.
Which makes me wonder: would this hold true for other planets that have thunderstorms over them as well and could we detect this here? Or is attenuation due to distance such that the signal would be lost in the noise?
