Abstract
A specific feature of surface layer electricity research is the requirement for synchronized measurements and subsequent data interpretation to accurately distinguish and evaluate the impact of local disturbances and global electric field variations on observed electrical characteristics. To address the challenge of interpreting atmospheric electricity measurements, a mathematical model is required to establish a definitive link between global and local disturbances and the measured values. This paper presents a potential implementation of such a model in the form of a total current equation describing the daily dynamics of the electric field intensity in the surface air layer. The spatiotemporal structure of the turbulent surface air layer, which is formed under the influence of a global unitary variation in the ionospheric potential and a local turbulent generator with independent daily dynamics, has been studied. The work generalizes studies of daily variations in the electric field strength of the surface layer for the cases of constant total current at the upper boundary of the surface layer. The profiles of electric field strength, conduction current density, and turbulent current density at different times during the day were calculated. Their dependence on the degree of turbulent mixing in the surface air layer has been established. The calculation results can be useful in analyzing data from ground-based atmospheric-electric observations.
