Observation of thundercloud-related charged particles in Tibet


Abstract:

In order to measure the correlation between thundercloud and atmospheric charged particles, we have installed some atmospheric electric field meter at a site of the Tibet Air Shower Array (4,300m a.s.l.) since February 2010. In this paper, we report preliminary result of coincident observation of data from the array and atmospheric electric field during thundercloud in term of until January 2011 and investigation of the frequency of the thundercloud until February 2012 by assuming some conditions of the thundercloud with the high energy particles. As the preliminary result, we observed the evidence that high energy particles more than 3 MeV significantly increased from the observation data with the passage of the thundercloud. It was found that the thundercloud in this area occurred mainly between winter season and summer. In addition, we found some periodicities of the occurrence frequency of the thundercloud.
