Abstract
Theoretical asymptotic methods have shown that the electric charge relaxation effect affects the physical characteristics of the electromagnetic radiation of the oscillating charged droplet. Analytical expressions are obtained for frequencies, decrements of attenuation of capillary oscillations of droplets due to viscous attenuation and energy losses on radiation. It has been shown that the frequencies of electromagnetic radiation of cloud droplets, realized in the ranges of hundreds of kilohertz and megahertz units, decrease with an increase in the radius and charge parameter of the emitting droplet, as well as attenuation decrements associated with radiation. Intensity of emission of electromagnetic waves decreases with decrease of electrical conductivity and mobility of charges in liquid.
