Simulation of rocket seeding of convective clouds with coarse hygroscopic aerosol: 2. Condensation and coagulation processes in cloud zones seeded with hygroscopic particles

Abstract

The closed system of equations is derived to describe the variation in dispersion of cloud environment due to the processes of condensation and gravity coagulation in the zone of salt particle propagation at hygroscopic seeding of convective clouds with antihail rockets. The competition for moisture between natural cloud droplets entrained into this zone from ambient cloud air due to turbulent diffusion and by artificial salt NaCl particles is considered. The problems of optimal methods for hygroscopic seeding of convective clouds with a view to enhance forced precipitation are discussed.
