Operational and reliable information about thunderstorms and lightning discharge parameters allows you to solve many problems of aviation, meteorology, energy, atmospheric physics, earth electricity and even near-Earth space. This article discusses issues related to the features of the development of thunderstorm processes and the parameters of lightning activity for the territory of the North Caucasus. The features of the risks associated with intense lightning activity are discussed. Information about electrical processes in the clouds and lightning parameters for 2009-2019 was obtained using the Vaisala LS 8000 network of lightning registers. The article gives a picture of the spatial distribution of the foci of the maximum intensity of lightning discharges in the North Caucasus and the distribution of the maximum value of the total absolute current of discharges per minute to the ground. The statistical features of the distribution of the intensity values of the discharges per minute by types of discharges encountered throughout the year were investigated. The performed analysis of these distributions made it possible to select the optimal approximating expressions for practical application in lightning protection. The main factors affecting the obtained characteristics of the spatial distribution of lightning activity are identified. Conclusions are drawn on the prospects for further research in order to obtain comprehensive information about electrical processes in the atmosphere of the region.
