Abstract

The paper focuses on ground-based aerosol generators, which become increasingly often used in the world practice of cloud seeding to control precipitation and prevent hailstorms. The results of theoretical and experimental estimates of the reagent distribution in the atmospheric boundary layer during the operation of ground-based aerosol generators are given. It is shown that the concentration of silver iodide recorded in the atmosphere was above background values to a height of 1200 m at distances from 3 to 9 km from the generator installation site. The results of the experiment on the precipitation enhancement in the Republic of Crimea demonstrated that when clouds passed over generators, the height of their tops, their maximum reflectivity, and precipitation intensity increased, which indicates a positive effect of generators on clouds. Conclusions are made about the prospects of using ground-based aerosol generators as a complement to the aircraft method, especially when seeding clouds at night and in the regions with mountain terrain.
