Modern aspects of Schumann resonance studies
- Schumann resonance (SR) is an electromagnetic extremely low frequency (ELF) phenomenon that occurs in the natural cavity formed by the Earth's surface and the lower ionosphere. Electromagnetic radiation of global thunderstorms is the source of ELF oscillations. Schumann resonance studies provide valuable information on the properties of the lower ionosphere together with the characteristics of planetary lightning activity. In the present article, modern aspects of the Schumann resonance studies are discussed based on numerical simulations of the ELF radio signals.
The contingency of parameters of human encephalograms and Schumann resonance electromagnetic fields revealed in monitoring studies

- The contingency of variations in amplitude—frequency parameters of the main modes of extremely-low-frequency resonances of an ionospheric waveguide (Schumann resonances) and changes in human encephalograms in the frequency range of 6–16 Hz has been studied. The results obtained with the use of synchronized monitoring suggest that such contingency, expressed as indices of cross-correlation function, is statistically significant, varying from 0.12 to 0.65 at α = 0.95. It has been established that contingency is largely determined by the current level of solar and geomagnetic activity.
