This work presents the results of a comparison between the global storm activity rate I sub(R) sub(S) and electric field intensity E sub(0) sub(Z). The permanent analysis of the I sub(R) sub(S) may become an important tool for testing Global Electric Circuit models. I sub(R) sub(S) is determined by a new method that uses the background component of the first 7 Schumann resonances (SR). The rate calculations are based on ELF observations carried out in 2005 and 2006 in the observatory station ''Hylaty'' of the Jagiellonian University in the Eastern Carpathians (Kulak, A., Zieba, S., Micek, S., Nieckarz, Z., 2003. Solar variations in extremely low frequency propagation parameters: I. A two-dimensional telegraph equation (TDTE) model of ELF propagation and fundamental parameters of Schumann resonances, J. Geophys. Res., 108, 1270, doi:10.1029/2002JA009304). Diurnal runs of the I sub(R) sub(S) rate were compared with diurnal runs of E sub(0) sub(Z) amplitudes registered at the Earth's surface in the Geophysical Observatory of the Polish Academy of Sciences in Swider (Kubicki, M., 2005. Results of Atmospheric Electricity and Meteorological Observations, S. Kalinowski Geophysical Observatory at Swider 2004, Pub. Inst. Geophysics Polish Academy of Sciences, D-68 (383), Warszawa.). The days with the highest values of the correlation coefficient (R) between amplitudes of both observed parameters characterizing atmosphere electric activity are shown. The seasonal changes of R, I sub(R) sub(S) and E sub(0) sub(Z) are also presented.
