Description / Table of Contents:
Two compressed air systems for glaciating supercooled clouds were studied in the laboratory. The first system used the sudden expansion of compressed air and was found to be most efficient at 27 psig producing an average of 5.2 x 10^8 ice crystals per cm^3 of air. The second system used a continuous flow of air through nozzles of various designs, of which the supersonic nozzle was found to be the most efficient, producing a maximum of 2.5 x 10^8 crystals per cm^3 of air at 27 psig. The above data were obtained at an ambient temperature of -4°C, but data for other temperatures and pressures were obtained and are presented in the text.
