| Abstract: | In order to study the factors influencing the formation of the vertical component of atmospheric electric field (AEF) strength E z , the data on meteorological parameters (atmospheric pressure, air temperature, and snow depth) are applied, as well as the data of radon Rn emanation into the atmosphere. Determined is the seasonal dependence on the radon emanation to the atmospheric surface layer due to the decrease in the upper soil layer permeability in wintertime that results in the decrease in the surface layer ionization which explains the difference between the maximum and minimum values of electric field strength within the annual variations amounting to ～100 V/m for the observational period. It is demonstrated that during the negative mean diurnal temperatures (November-April), the cyclone arrival from southern directions is accompanied by significant decrease in AEF E z due to the increase in the radon flow under the influence of considerable fall of atmospheric pressure and dramatic warming by 10–15°C resulting in the increase in upper soil layer permeability. |
