Description
In the study, estimates of the surface electric field variability in undisturbed atmospheric conditions in Tomsk were obtained. It is noted, the average and mode of the potential gradient in Tomsk under fair-weather conditions are ~280 and 250 V/m, and it is a typical range is 160-370 V/m. The diurnal variations in potential gradient per year on average are characterized by oscillations of the continental type with a double maximum and minimum. The main minimum of diurnal variations is 7 h and the main maximum is 21 h of local time (00 and 14 UTC, respectively). According to the annual mode, the maximum potential gradient is observed in February, and the minimum is recorded in June. In the warm period of the year, the average and range of the potential gradient are 1.2 and 1.5 times, which less than in the cold period.
