Аннотация доклада:
We have theoretically estimated ULF spectra on the ground and at the ionosphere altitudes in the frequency range of the ionospheric Alfven resonator (IAR). The IAR has been considered to be excited either by a separate intense lightning stroke or stochastic global thunderstorm activity. The IAR excitation during daytime and nighttime has been compared. The influence of the IAR eigenfrequency latitudinal inhomogeneity on signatures of the spectral resonance structure has been modeled. Results of calculations are compared with the power spectra recorded at low-orbiting satellites (Aureol-3, C/NOFS, CHAMP) and feasibility of the IAR response to the atmospheric lightning activity at low-orbiting satellites is indicated.
