Laboratory Studies of Compressed Air Seeding of Supercooled Fog.

Abstract

Some 400 tests were conducted in the CRREL Cold Cloud Chamber to determine the combination of air pressure and nozzle design that yielded the maximum production of ice crystals in a supercooled fog. It was found that some 0.22 cu m/min of air which was compressed to 517 kPa is needed to be effective for clearing a supercooled fog.
