Yellowstone Field Research Expedition VIII,

Abstract

Vonnegut (1948) demonstrated that rapid expansion of moist compressed air could be used to produce vast quantities of ice embryos for seeding supercooled clouds. This phenomenon was studied by Schaefer (1953) with systematic laboratory experiments. In conjunction with high velocity wind tunnel and turbine research, Hill (1965) and others have recently studied the nucleation of water vapor and other gases in the rapid expansion of compressed air from supersonic and hypersonic nozzles. From these reports, the Navy Weather Research Facility (NAVWEARSCHFAC) has attempted to develop a theory for optimum compressed-air seeding techniques.
