SCHUMANN RESONANCE FOR CONDUCTIVITY PROFILE OF ATMOSPHERE WITH SINGLE BENDING
摘要
Investigations remains update of relationship between the parameters of global electromagnetic (Schumann) resonance and characteristics of vertical profile of atmosphere conductivity. We use the rigorous full wave solution of the electrodynamic problem in the spherical Earth-ionosphere cavity and compare the results with the described in literature heuristic knee model having a single kink. By using parameters of this heuristic model, we constructed vertical profile of atmospheric conductivity and used it in the rigorous full wave solution for the propagation constant of ELF radio waves. Afterwards, the power spectra were computed of vertical electric and horizontal magnetic fields in the framework of the uniform global distribution of the planetary thunderstorm activity. We show that conductivity profile based on the one kink does not match the rigorous full wave solution and the subsequent computations of the power spectra of the Schumann resonance.
