Abstract:The results of gamma emission observations obtained during thunderstorms at Tien-Shan Mountain Cosmic Ray Station are presented. The energy spectrum radiation of the stepped leader gamma radiation is measured. The total energy of stepped leader emitted in gamma rays is estimated as 10−3-10−2 J. The experimental results are in an agreement with the runaway breakdown mechanism.
Keywords:Lightning   Gamma emission   Runaway breakdown
