Research Abstract

To observe the evidence that particles in the thundercloud are accelerated, we installed two atmospheric electric field meter at the Yangbajing international cosmic ray observatory (Tibet, China) since February, 2010. We have observed the strength of the atmospheric electric field and the counting rate of particles (i.e., gamma rays or electrons) by a part of scintillation counters in the Tibet air shower array. We detected many events that show strong correlation between the electric field variation and the counting rate of particles under our preliminary analysis. We continue the observation to increase the evidence of this correlation and analyze data in the future.
