Abstract

A precipitation enhancement cloud seeding program was funded by the Monterey County Water Resources Agency, Salinas, Caiifomia during the winter seasons of 1991 through 1995. The operations were designed and conducted by Atmospherics Incorporated, Fresno, California. The target-control precipitation analyses show highly suggestive positive results on the order of 41% more rain in the target area than the control areas during the cloud seeding episodes. Since only a part of the rain seasons were seeded, this represents a 23% increase in annual precipitation over the target area. However, statistical tests did not provide conclusive evidence to support these initial findings.
