SURFACE LAYER ELECTRICITY RESEARCH: MODELING AND EXPERIMENT

Abstract

The article presents a comparative analysis of the numerical and analytical modeling results
of the electrode effect in the atmosphere, as well as experimental studies of electrodynamic processes
taking place in the surface layer. For the analysis, several electrical characteristics of the
surface layer in the atmosphere were used, namely, the values of the parameters of the electrode
effect determined by the number of positive and negative aeroions at different altitudes from the
earth's surface. Studies have been carried out for various models under various meteorological
conditions in approximations of the classical (non-turbulent) and turbulent electrode effect, both
in a clean atmosphere and taking into account aerosol air pollution. The independence regularity
of the electrode effect value as a whole (the amplification of the electric field at the surface compared with the upper boundary of the formed electrode layer) from atmospheric conditions with
various methods of mathematical and numerical modeling is revealed. It is established that the
height of the electrode layer and, accordingly, the scale of the electrical characteristics distribution
change significantly when various factors, such as ionization and aerosol air pollution, the
presence and intensity of turbulent and convective transport, act on the near-surface layer of the
atmosphere. The verification of approximate analytical models was carried out by establishing the
correspondence between the results of numerical modeling, theoretical calculations and experimental
studies obtained earlier. The data of theoretical and numerical calculations in various
ways are in good agreement with each other and with the results of experimental atmosphericelectrical
observations. Conclusions are drawn about the possibility of using approximate analytical
expressions obtained by mathematical modeling methods to describe the electrodynamic
structure of the atmospheric lower layer.
