雷暴内部的强大气电场对宇宙射线空气阵雨的电磁成分有显著影响。探测这种效应对于理解阵雨和闪电之间的关系尤为重要。ARGO-YBJ实验记录了雷暴期间大气电场剧烈变化对单粒子计数率的影响。其中一个事件发生在2009年7月20日上午（北京时间）。低能量的单粒子计数率在短时间内（~ 20分钟）显著增加，而高能量的单粒子计数率则下降。
The strong atmospheric electric fields inside thunderstorms can have a significant effect on the electromagnetic component of cosmic ray air showers. Detecting this effect is particularly important in understanding the relation between the showers and lightning. Some episodes in which intensely changed atmospheric electric field during thunderstorms affect the counting rate of single particle have been recorded by ARGO-YBJ experiment. One of the episodes is discussed carefully, which happened in the morning of July 20, 2009 (Beijing Time). A short duration (∼20 minutes) significant increase of the single particle counting rate with low energy occurs accompanied with strong atmospheric electric field, while a decrease happens in the counting of particles with higher energy.
