本文介绍了在雅库茨克、米尔尼和涅龙格里三个雷暴点探测器的作用半径为300公里的帮助下，在雅库特中部和南部观测得到的雷暴核的特征。通过两步聚类分析，得到了雷暴核的主要参数：放电次数、面积、强度、横向和纵向尺寸、形状和寿命。单元格出现面积的分布呈指数下降形式。结果表明，随着雷暴中单个核的平均面积增大，雷暴所占的面积呈指数增长，而核的放电密度随核面积的增大而减小，这种关系可以用指数形式表示。雷暴在放电密度上的百分比分布可以用下降幂律函数来描述。
Characteristics of thunderstorm cores, obtained from observations in Central and South Yakutia with the help of three one-point thunderstorm detectors with a radius of action of 300 km, located at Yakutsk, Mirnyi, and Neryungri, are presented. As a result of processing performed using two-step cluster analysis, the main parameters of thunderstorm cores have been obtained: number of discharges, area, intensity, transverse and longitudinal dimensions, shape, and lifetime. The distribution over occurrences of areas of cells has an exponentially falling form. It is shown that with increase of the mean area of an individual core Sco in a thunderstorm, the area occupied by this thunderstorm Sth grows exponentially, but with increase of the area of cores the density of discharges in them falls, and this dependence can be written in exponential form. The percent distribution of thunderstorms over density of discharges can be described by a falling power-law function.
