Abstract : This report covers the results of two years of field testing to determine the existence, magnitude and causes of large scale effects of cloud seeding. The field program was located north and east of an ongoing research seeding project by North American Weather Consultants under contract to the Naval Weapons Center. Substantial evidence is presented showing that precipitation has been more than doubled over a large area about 70 miles downwind from a point seeding source in Santa Barbara County, California. The causes of these increases have not yet been determined, but preliminary results indicate they are related to air mass temperature and wind speed and direction.
