Assessment of Lightning Parameters during Thunderstorm Development in Yakutia

The study presents an analysis of the parameters of lightning strokes, estimated by radiophysical observations. The intense thunderstorms that occurred in Central Yakutia in 2016-2017 are considered individually. The thunderstorms in June 2016 spatially developed with the predominant component of direction from east to west in ~ 60% of events, and in July-August ~ 80% of thunderstorms had a direction of movement from west to east. In the summer of 2017, the general direction of daily lightning strokes occurrence was from west to east. One can note there was an increased proportion of cloud-to-ground lightning during the initial and final hours of thunderstorm, and the number of positive strokes had grown after peak stage of lightning activity. The lightning location network makes it possible to estimate the energy emitted by a lightning stroke from the amplitude of the received signals.
