Investigating the locations of electron acceleration in Hokuriku winter thunderclouds using on-ground gamma-ray and radio observations
July 25, 2023
Gamma rays from thunderclouds are direct evidence of ~30 MeV electron acceleration by static electric field in the sky. On 2021/12/30, five consecutive Terrestrial Gamma-ray Flashes (TGFs) were detected by our gamma-ray detectors placed on Kanazawa City, Japan. Although analog signals of our gamma-ray detectors were severely saturated, timing of the five TGFs were well constrained and compared with radio observations. We detected four slow radio pulses associated with the first four TGFs, which were located ~3 km south from the on-going upward negative lightning discharge. Our results suggests that the TGF's acceleration location can be a few km apart from the leader development of the main discharge activity.
