INFLUENCE OF SURFACTANT VAPOR ON THE SPECTRUM OF CLOUD DROPS FORMING IN THE PROCESS OF CONDENSATION GROWTH

Introduction of a highly disperse aerosol of higher fatty alcohols int o the zone of an ascending current under cumuli results in that a grea ter part of droplets are passivated, and in cumuli there are provided conditions for the preferred growth of large drops. One has numericall y solved a system of equations describing variations in the supersatur ation of a cloud system, condensational growth of drops, and kinetics of adsorption of surfactant vapor on the surface of drops. The calcula tion results indicate that small droplets are passivated, the number o f growing drops increases, and the growth of large drops is accelerate d.
