Observation results accumulated to date show that the processes of mechanical charge transfer in the surface atmosphere play an important role. Mechanical transfer current can be considered as a local generator of electric field acting everywhere in the surface atmosphere layer. Operation regularities studies of such a generator will make it possible to evaluate its effect on the formation of the electrode layer structure. To do this, it is necessary to identify the connections between the mechanical transfer current and other physical factors, which is a complex multiparametric task, the solution of which is facilitated by the analysis of experimental data on the electrical and meteorological characteristics of the atmosphere surface layer. The paper discusses the results of current density measurement of mechanical transfer from the atmosphere to the ground, obtained during a long-term expedition experiment in the Rostov region. Simultaneously with measurements of current density, meteorological parameters were recorded: air temperature, wind speed and direction, vertical air velocity at different levels. To assess the effect of meteorological parameters describing the thermodynamic state of the surface atmosphere on charges transfer under the influence of mechanical forces the method of one-way analysis of variance was used. The F-test calculated according to measurement results in the Rostov region for each investigated case made it possible to reveal the high reliability of this effect.
