PRACTICAL EXPERIMENTS WITH A MIXTURE OF SODIUM CHLORIDE AND CEMENT AS A REAGENT FOR SEEDING LARGE CUMULUS CLOUDS

Abstract

The paper reviews the results of artificial rain-making by seeding convective clouds with a mixture of sodium chloride and cement. Light to moderate artificial rain, lasting from 15-30 minutes to an hour, was produced in 57% of the cloud-seeding cases involving the use of a hygroscopic reagent. The best results were achieved by the use of 4 kg to 1 kg of the reagent per 1 km of cloud area. The area covered by the artificial rain was 1-5 kilometers but more often 2-3 kilometers. The maximum possible quantity of artificial precipitation did not exceed 5% of the average monthly natural rainfall. In most cases a positive seeding effect was achieved with clouds whose vertical thickness exceeded 2.4 kilometers.
