Abstract
Using the monitoring data of electrical quantities of a surface layer in Tomsk in 2006-2017, the their slow variations connected with passage of cumulonimbus ( Cb ) clouds and concomitant weather phenomena in the warm and cold seasons were studied. In total, 453 and 210 events for warm and cold seasons, respectively, were considered. A statistical analysis of these slow variations in the electric field potential gradient was carried out. The distribution of the total duration of the potential gradient slow variations is described by the power-series distribution (Pareto distribution).
