Abstract

An increase in the flux of energetic particles under thunderstorm clouds is a result of the multiplication and acceleration of particles of secondary cosmic rays in the electric field of the cloud. Study of the particle multiplication mechanisms requires an assessment of the electrical properties of clouds. In this paper, we propose a method for evaluating the electrical structure of a cloud that creates a flux of energetic particles. The developed technique for estimating the distribution of a charge in the cloud is based on the ground-based measurements of the electric field and energetic particle flux. The technique was used to study the clouds that create the descending fluxes of energetic particles observed at the Aragats Research Station. The characteristic charge distribution involves a two-layer structure with a charge density of 0.5–5 nC/m³ in the lower layer and –0.2…–3 nC/m³ in the upper layer. The total charges of the two charge regions are in the range of 1– 20 and –1…–30 C, respectively.

根据云中测得的高能粒子通量评估云中的电荷分布

摘要

雷暴云下高能粒子通量的增加是由于云层电场中二次宇宙射线粒子的繁殖和加速的结果。对粒子增殖机制的研究需要对云的电学性质进行评估。在本文中，我们提出了一种用于评估产生高能粒子通量的云的电子结构的方法。用于估算云中电荷分布的已开发技术是基于电场和高能粒子通量的地面测量。该技术用于研究在Aragats研究站观测到的产生高能粒子下降通量的云。特征电荷分布涉及两层结构，电荷密度为0.5–5 nC / m³在下层和-0.2 ... -3 NC /米³的上层。两个电荷区域的总电荷分别在1-20和–1…–30 C的范围内。
