Description
ith its large effective area and good time resolution, LHAASO provides a valuable opportunity to study thunderstorm-related high-energy atmospheric phenomena. By analyzing LHAASO-KM2A data and atmospheric electric fields, we observe an increase in particle numbers during thunderstorms caused by thunderstorm ground enhancements (TGEs). Nearly at the same time when some of the TGEs are terminated by lightning strikes, a large number of detectors are fired in a very short time duration, which could be either induced by an electromagnetic pulse or a possible downward terrestrial gamma-ray flash (TGF).
