Description
Galactic cosmic ray (GCR) flux registered by the ground-based neutron monitors, as well as by space instrumentation, such as ACE or AMS, provides persistent information about events originating from the Sun. In this study, we examine time periods of sporadic Forbush decreases that occurred during the rising phase of the 24th solar cycle. We analyze various parameters related to solar, heliospheric, and geomagnetic activity during these periods, using different machine learning techniques. Moreover, we compute the geoelectric field in the Poland region for these periods using a 1-D layered conductivity Earth model. On the base of these parameters, we investigate the changes in the number of transmission line failures in southern Poland. Our findings indicate an increase in the average number of failures during the appearance of solar transients in the GCR flux, suggesting a potential coupling between these events.
