The atmospheric precipitations influence on electrical parameters of atmospheric surface layer during a transition period of year
The variations of atmospheric surface layer plasma characteristics, such as electric field potential gradient and air polar electrical conductivities, during the passage of cumulonimbus clouds and the atmospheric precipitation of various types (rain, rain and snow mixed, snow) during the periods September - November and April - May 2014-2016 years are investigated. The microphysical parameters and intensity of precipitation were estimated by the optical precipitation gauge OPTIOS, developed in IMCES SB RAS. During intense precipitation there was noted a significant discrepancy between the values of Ñj, measured two electric field sensors. In the dynamics of air polar electrical conductivities during the selected events there are noted the effects characteristic both for the warm and the cold period of the year, as well their transition.
