Abstract
The time variations in the galactic cosmic ray (GCR) intensity at Apatity stations have been compared to the amplitude of the first Schumann resonance (as an indicator of the global thunderstorm activity power) for 12 cases of Forbush decreases in GCRs. A performed analysis indicated that the amplitude of the first Schumann resonance decreased only once during a Forbush decrease in GCRs as compared to the quiet conditions (during the strongest event in January 2005). In the remaining cases, a statistically significant effect was not observed.
