“…During the solar proton events (SPE), high-energy particle precipitation is often accompanied by X-ray bursts leading to significant perturbations of the conductivity in the cavity. Different shifts of the SR parameters were reported in the realistic measurements [e.g., Schlegel and Füllekrug, 1999;Roldugin et al, 2001Roldugin et al, , 2003Roldugin et al, , 2004aSátori et al, 2005]. In our previous work [Yang and Pasko, 2005], the variation patterns of the first SR frequency associated with the ionospheric conductivity perturbation during SPEs and X-ray bursts were discussed.…”

[1] The diurnal and seasonal variations of Schumann resonances (SR) have been reported in a number of experiments. In this paper, a three-dimensional FDTD model of the Earth-ionosphere cavity with a day-night asymmetric conductivity profile is employed to study the diurnal and seasonal variability of the power and frequency of the first Schumann resonance (SR) mode. Comparison of the FDTD results and recent experimental measurements shows a clear modulation in the SR power related to the local ionospheric height and global lightning activity. It is found that SR frequencies are not only a function of the local time but also are controlled by the global lightning activity changing with universal time.

The electromagnetic eigenmodes of Earth-ionosphere global resonator known as Schumann Resonances (SR) are excited by global lightning activity. The simultaneous measurements of electric field in the ELF (~5 -100 Hz) frequency band at two observatories clearly reveal the global character of the resonator response to the excitation both in the permanent Schumann background as well as in isolated events (transients). It is shown that measurement of ELF electric field can be done with relatively simple equipment.

[1] The measurements of horizontal electric components at extremely low frequencies (0.1-20 Hz) have been started in the high-latitude observatory of Lovozero in the Kola Peninsula. It is found that the electric components are not less informative than the horizontal magnetic ones for Schumann resonance study. The diurnal variations in amplitude, frequency, and bandwidth of the first Schumann resonance mode in the electric W-E and N-S components are similar to the variations in the magnetic H and D components, respectively. The same correspondence of the components keeps for Q bursts. The frequencies in electric and magnetic components are not always equal: In summer, the frequency of the electric N-S component in the diurnal variation exceeds the frequency of the magnetic D component by 0.1 Hz. The parameters of both magnetic and electric components have seasonal variations. Three maxima of thunderstorm activity are observed in daily variations of the amplitudes of electric components: the Asian and American ones in the W-S component and the African one in the N-S component. The width of resonance bands in the electric components is somewhat larger than in the magnetic ones. The calculations of ELF wave components near poorly conducting surface are made, the results being in accordance with the observations. Citation: Roldugin, V. C., A. N. Vasiljev, and A. A.
