Abstract :
In the paper, long-term data sets of the Schumann resonance (SR) signals observed at the Ukrainian Antarctic Station (UAS) are analyzed. It has been found that the long-time trends of the peak frequencies and intensity of the fundamental SR mode correlate with 11-year solar cycle. No trend of yearly averaged numbers of lightning flashes is observed in LIS satellite data for the same period. It is suggested that the long-term variations of the intensity and frequency of SR peaks were caused by changes in the ionosphere controlled by solar activity.
