Project Foggy Cloud IV. Phase II. Warm Fog Modification by Electrostatically Charged Particles

Abstract

INSTRUMENTS, ELECTROSTATICS, NOZZLE GAS FLOW, TEST METHODSWEATHER MODIFICATION, *FOG DISPERSAL, FOGGY CLOUD 4 PROJECTFoggy Cloud IV, Phase II, is part of a continuing series of experiments concerning the modification and dispersal of warm fog. The primary purpose of Phase II was to evaluate the use of electrostatically charged particles as a means of improving visibility in warm fog. A charged-drop-producing system comprising an inducation charging system and a water delivery system was developed for charging and delivering water drops. Tests were conducted at the Arcata-Eureka airport, McKinleyville, Calif., from 14 September to 5 November 1971, using a manned hot-air balloon as a research platform. Although a practical charging and delivery technique was developed, testing was inconclusive because of the lack of fog and the encountering of an unanticipated phenomenon, termed 'ground effect'.
