Rapid Thunderstorm Charging Produces Strong Gamma‐Ray Glows

by Xiushu Qie 21 March 202520 March 2025

A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely resemble terrestrial gamma-ray flashes.
