Abstract:From the yearly averaged diurnal variations of the first Schumann resonance frequency, corresponding changes in the area covered by global lightning were calculated and then compared with optical observations made by satellite 11 years later. The data observed are characterized by the high cross-correlation coefficient. The conclusion is that Schumann resonance frequency variations are an indicator of the thunderstorm distribution over the globe.
