Abstract

The influence of micrometeorological parameters (wind speed, temperature stratification and atmospheric stability) upon electric polar conductivity, potential gradient, vertical total current density and vertical convection current density is studied by means of power spectral and coherence spectral analysis. The analyses show great variations in the atmospheric electric parameters for frequencies corresponding to the diurnal wave (0.042 cph) and in many cases great variances are noted for the frequencies 0.083, 0.125 and 0.17 cph. The influence of the micrometeorological parameters upon atmospheric electricity seems to be significant for these frequencies. Annual changes of the power and coherence spectra are also observed.
