Terrestrial gamma-ray flashes as the high-energy effect of tropospheric thunderstorms in near-Earth space

Thunderstorms in the troposphere produce lightning flashes and cause charge transfer of different strength at varying spatial and temporal scales, leading to various forms of transient electromagnetic effects in the vast space above thunderstorms. In particular, normal intra-cloud (IC) lightning can...
