同时测量伽马射线微分能谱，电场干扰，和气象条件提供的实验设施位于山。亚美尼亚Aragats允许建立雷暴大气中粒子加速和传播的模型。我们对测量的和模拟的雷暴地面增强（TGE）进行了比较。大多数TGE的起源是MOS过程-宇宙线电子的能谱在大气电场中的修改。伽马射线微分能谱可以用幂律函数很好地描述，其指数在3400 - 5000 m a.s.l.的电场强度为0.8 - 1.5 kV/cm的范围内。实验和模拟的TGE特征的良好的一致性，提供了希望的TGE伽马射线能谱的观测参数估计云内电场。
Simultaneous measurements of the gamma ray differential energy spectra, electric field disturbances, and meteorological conditions provided by experimental facilities located at Mt. Aragats in Armenia allows to establish the model of particle acceleration and propagation in thunderstorm atmosphere. We present comparisons of measured and modeled thunderstorm ground enhancements (TGEs). The origin of the majority of TGEs is the MOS process —the modification of energy spectra of cosmic ray electrons in the atmospheric electric fields. The gamma ray differential energy spectra are well described by the power law function with indexes in the range for the electric field strengths 0.8−1.5 kV/cm at altitudes of 3400−5000 m a.s.l. The good agreement of the characteristics of experimental and simulated TGEs gives hope to estimate the intracloud electric field by the observed parameters of TGE gamma ray energy spectra.
