Analysis of the Atmosphere Ground Layer Electrodynamic Model

The paper presents the results of analyzing the atmosphere surface layer electrodynamics model using the methods of similarity theory. In the electrode effect approximation, the mathematical model is presented in the form of a nonstationary initial-boundary value problem for a parabolic type equation. The correctness of using various types of electrodynamic models depending on meteorological conditions in the stratified surface layer is substantiated. Estimates of the characteristic scales of the electrode layer are obtained depending on the meteorological parameters of the atmosphere, which can be used in modeling problems of electrodynamics of the surface layer. For the case of neutral stratification of the atmosphere, a procedure has been implemented to reduce the system of equations of the electrode effect to a dimensionless form and obtain similarity criteria. Models of a classical, turbulent, convective-turbulent electrode layer were constructed, and approximations were obtained for the cases of intense turbulent mixing and strong convective transfer by splitting them into physical processes.
