Currently, many researchers have an interest in the investigation of the electric field in the fair-weather electric environment along with its diurnal and seasonal variations across all regions of the world. However, a similar study in the southern part of Western Siberia has not yet been carried out. In this regard, the paper aims to estimate the mean values of the electric field and their variations in this area using the example of Tomsk. The time series of one-minute average potential gradient values as well as other quantities obtained from the geophysical observatory of the Institute of Monitoring of Climatic and Ecological Systems of the Siberian Branch of the Russian Academy of Sciences (IMCES SB RAS, Tomsk, Russia) from 2006 to 2020 is used in this study. The mean annual value of the potential gradient in Tomsk is 282 V/m and usually varies from 161 to 372 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.

Динамика уровня обводненности болот в южнотаежной подзоне Западной Сибири в среднем и позднем голоценеРабота выполнена при поддержке гранта РФФИ № 18-45-703003/р_мол_а. Проведен сравнительный анализ динамики уровня обводненности болот в голоцене. Материал для анализа -четыре торфяные колонки, отобранные на разных болотах на территории южной тайги Западной Сибири. Для трех выполнена количественная реконструкция уровня болотных вод по данным ризоподного анализа торфа при помощи трансферной функции. На одном из болот осуществлена реконструкция атмосферных осадков по палинологическим данным информационно-статистическим методом Климанова. Выделены 6 этапов синхронного повышения уровня обводненности большинства
