AIR WEATHER SERVICE WEATHER-MODIFICATION PROGRAM.
Abstract
The Air Weather Service has recently inaugurated a program to field test those weather-modification techniques within the scientific state-of-the-art and of potential value to the Air Force in order to bring them to a state of operational readiness. The following fog-dissipation projects are described and the results presented: (1) Project Cold Fog: dissipation of supercooled fog by the use of dry ice cakes suspended from tethered balloons. (2) Project Cold Cowl: an operational project to dissipate supercooled fog by means of crushed dry ice dropped from an aircraft. (3) Projects Cold Wand and Cold Horn: dissipation of supercooled fog by injection of liquid propane and carbon dioxide, respectively, directly into the fog. (4) Project Cold Fan: a repeat of Cold Horn with the addition of a powerful vertical fan to blow the resulting ice crystals aloft. (5) Project Warm Fog: dissipation of warm fog by means of the engine exhaust heat from parked C-141 aircraft. (Author)
