Simulation of rocket seeding of convective clouds with coarse hygroscopic aerosol. 1. Condensation growth of cloud droplets on salt crystals

Abstract

Laws of aerosol particle distribution at hygroscopic seeding of convective clouds by means of antihail rockets are considered. Influence of salt particle dispersion degree on intensity of condensation growth of separate cloud droplets on these particles is investigated. Analytical formulae describing variation of radius of NaCl crystal and cloud droplet growing on the salt crystal until its entire dissolution in the droplet are obtained. On the basis of numerical calculations, comparative analysis of salt influence on intensification of condensation growth of droplets in the cloud is carried out.
