Description
Summary:We performed combined radiometric and radar measurements of the integral water content of a small-drop fraction of rain cloud systems with allowance for the multiple scattering phenomena. The contribution of rain to emission of the "cloud-rain" system was calculated on the basis of the vector equation of radiation transfer, which enabled us to allow for all orders of multiple scattering by spherical rain drops within the framework of the model of statistically independent particles. It was found that the maximum of the integral water content of overcooled water in clouds does not correspond to the maximum of precipitation intensity. The characteristic values of the integral and specific water contents of a small-drop water fraction in cloud systems with precipitation are measured.[PUBLICATION ABSTRACT]
