On heterogeneous structure of atmospheric current in various meteorological conditions according to the Kola Peninsula observation data

According to results of observations at Apatity station in the end of summer-beginning of autumn of the year 2006, investigations of aeroelectric characteristics of the surface layer of atmosphere for various meteorological conditions are carried out to find out the spatial structure of atmospheric currents. Horizontal scales of aeroelectric heterogeneities at the wind speed of 2–6 m/s are evaluated using statistical methods. It is shown that the distribution function of raindrop charges is constant for one rain cloud during time interval of about 20 min, but can considerably vary from one cloud to another.
