Abstract : The work of the present project consists of four subjects: (1) Precipitation mechanisms and droplet coalescence, (2) case studies of seeded clouds, (3) cloud and storm development, and (4) electrification. The major effort to date has gone into item 1, specifically in developing the data handling aspects of the records from the continuous particle sampler including setting up a computer program to transform replica distributions into droplet distributions, and in trying to understand and evaluate the various error factors involved. The system now permits the rapid handling of sampler data so that the study of precipitation mechanisms and seeed clouds can proceed efficiently, and the accuracy of the droplet data evaluation has been greatly improved. The data obtained from ascents up within cumulus cores still suggests but does not prove that significant coalescence is taking place between small droplets in the 5-10 micron diameter range.
