Nonlinear effects in the surface atmosphere based on the atmospheric-electrical measurements results

Proceeding from the results of measurements near the earth’s surface, nonlinear effects associated with the dependence of electrical conductivity on the electric field strength have been observed. This is manifested in the loss of proportionality of the conductivity current density from the field intensity, and the nonlinearity manifests itself more noticeably at low values of electrical conductivity. Based on the data obtained, empirical regression series have been constructed and equations of the dependence of polar electrical conductivity on the electric field strength have been obtained. In the interval of a sharp decrease in the values of polar conductivities with multiple amplification of the electric field strength, their interrelation is approximated by a linear function with a high level of reliability.
