Abstract

Acquiring knowledge of electric field strength and structure inside a thunderstorm is key to understanding lightning initation. Given data from the Telescope Array Surface Detector (TASD), we observed variations in cosmic ray shower intensity. These variations were found to be between 0.5-1% with and up to 2-3%, detected in both deficit and excess, and correlated with lightning and thunderstorms. To study these variations, we ran simulations of electric fields within thunderstorms using CORSIKA. These simulations yielded a result of electric field magnitude variations between 0.2-0.4V, which in turn has informed our understanding of the electric field within storms.
