摘要：

The electrical properties of the fog are described on the basis of full-scale aeroelectrical observations and theoretical modeling. The measured electric field and spectrum of its pulsations are given along with the simultaneous amplitude-time series of the vertical component of electric field and electric current. Fog is shown to increase the intensity of electric-field pulsations by more than an order of magnitude. Nevertheless, in the majority of observations, the exponent of the spectrum does not differ drastically from the spectrum exponents typical for fair-weather conditions. The results of structure-time analysis offer the possibility of specifying two types of electrical states of fog: one of them is characterized by aeroelectric structure generation and another, by chaotic structure-time variations. Possible mechanisms of electric-field profiles and spectra formation are discussed with allowance for fog-particle charging, neutral gas turbulence and aeroelectric structures in the fog.
