Simulation of Rocket Seeding of Convective Clouds with Coarse-dispersion Hygroscopic Aerosol. 1. Condensational Growth of the Cloud Droplets at the Salt Crystals

摘要

Patterns of propagation of aerosol particles generated in the hygroscopic seeding of convective clouds from antihail rockets is studied. Effects of the salt particle dispersity on condensational growth rate of separate cloud droplets on these particles are studied; analytical formulas are obtained as describing change of radius of the NaCl crystal and of the cloud droplet which grows on the crystal till the moment of full dissolving of the crystal in the droplet. Numerical computations are used for comparative analysis of the salt effect on intensification of condensational growth of the droplets in the cloud.
