Considered are the methods of thunderstorm cells clustering using the data of one-point and multipoint lightning detectors and their characteristic features based on the observations in Yakutia. As the thunderstorm activity intensifies, i.e., the lightning discharge density in the region increases, the number of storm centers and the number of cells in the center grow up. The sizes and the lifetime of thunderstorm cells in Yakutia correspond to the similar data for North America and the European part of Russia. The maximum area and intensity of both center and thunderstorm cell are observed at the stage of development, in the middle of their lifetime. As the cell area increases, the intensity of lightning discharges decreases inversely to the area. It is revealed that as the cell oblongness increases, the intensity of lightning discharges in these cells becomes higher as well.
