The paper presents the results of a three-year monitoring study of the magnetic component of the EM background in the Altay in the seasonal-daily observation cycle. Describe variations of resonant frequency and amplitude of the first three modes Schumann resonances.
The paper presents the results of a comparative analysis of the spectral characteristics of the Schumann resonances in the Russian Altai and the Tomsk Region for the period from 2015 to 2018.
The aim of the research is to analyze the contribution of close thunderstorms to the increase in the level of extremely low-frequency (ELF) electromagnetic (EM) background in the Siberian region. In this work, a technique for creating a response of close lightning discharges in magnetic induction components in the range up to 30 Hz is proposed and tested. The proposed method for joint analysis of synchronous monitoring data for local thunderstorm activity and variations of EM–focus is aimed at revealing the connection between the level of the EM background level and their parameters as the range and type of lightning discharge.
The aim of the research is to analyze the variations in the positional angles of polarization ellipses of the extremely lowfrequency (ELF) electromagnetic (EM) background in the seasonally-daily cycle of observations. The statistical estimation of the positional angles of the polarization ellipses was carried out for the first three modes of the Schumann resonances taking into account the time of the day and the season of the year for the observation period from 2013 to 2017.
