EVALUATION OF RESULTS OF JOINT AIR FORCE-WEATHER BUREAU CLOUD SEEDING TRIALS CONDUCTED DURING WINTER AND SPRING 1949

Abstract

The question of the modification of natural clouds by artificial seeding is examined in terms of current theoretical considerations as to the physical-chemical and meteorological effect of seeding agents on clouds. The results of experimental laboratory studies made in this country and abroad on the formation of the ice phase and precipitation are reviewed. The results of the joint Air Force-Weather Bureau seeding trials then are studied in light of these theoretical considerations. The combined theory and experiments point to little likelihood of large-scale weather control using present techniques.
