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.
As a result of many years of monitoring studies of extremely low-frequency electromagnetic fields in Tomsk, the polarization characteristics of the first three modes of the Schumann resonances were obtained. The analysis of the relationship between the positional angles of polarization ellipses of the Schumann resonance modes and the position of the centers of global thunderstorm activity taking into account the world time and the season of the year is carried out.
As a result of the organization monitoring studies at Baygazan (Russian Altay) and Kolarovo (Tomsk region), located at a distance of about 534 km, cut common and local patterns of behavior of extremely low-frequency (up to 30 Hz) electromagnetic background. A comparative analysis of the Schumann resonance parameters from a single methodic is carried out.
This paper presents a daily-season variation of the coefficient ellipticity and position angle of the ellipse polarization of the first three events of the Schumann resonances. A comparative analysis of the polarization characteristics was spending for the period 2013-2015 years.
The paper describes a method of magnetic measurements of natural electromagnetic fields ELF range. The results of the analysis of the frequency characteristics of fashion Schumann resonances in a suburban area in the seasonally-daily cycle of observations.
The article describes the experimentally determined distribution of ellipticity coefficient for the first three modes of the Schumann resonances (SR) for different seasons in 2014. Established the presence of seasonal variation of the frequency of occurrence for different types of polarization of the first three modes SR. It is shown that the frequency of occurrence of elliptical polarization for different modes of SR is about 70–80%. Circular polarization - a very rare event, the frequency of its occurrence is less than 1% for every season of the year.
The article describes magnetic measurements technique of natural electromagnetic fields in ELF range. The analysis results of the amplitude characteristics of the Schumann resonance modes in a suburban area in the seasonal cycle of observations is presented.
