Influence of geomagnetic disturbances on seasonal dynamics of daily variations in atmospherics

Daily variations were studied in atmospherics at frequencies of 600 Hz and 6 kHz, which were recorded on the Kola Peninsula from 2012 to 2013 in different geomagnetic conditions. It is shown that increased geomagnetic storminess does not significantly change daily variations in the hourly mean flow and amplitudes of atmospherics at either frequency for the west-east component. For the north-south component, this is true only for hourly mean amplitudes. The distribution of amplitudes of atmospherics recorded is satisfactorily described by the well-known formula P(X) = [1 + (X/X50)k]−1, where 1.9 < k < 2.9 for a frequency of 600 Hz and 1 < k < 2 for 6000 Hz.
