Description:
Cloud seeding operations took place over a 10,000 square mile area in Central Arizona during the first four months of the winter of 1951. The natural precipitation for these months in this area was estimated by a simple correlation method utilizing an adjacent unseeded region. The actual precipitation consistently exceeded the estimated natural precipitation. The apparent precipitation increases were roughly proportional to the amount of cloud seeding equipment used. Although the correlation technique applied is rather inexact, it seems sufficiently accurate to make the consistent precipitation increases suggestive of a large positive effect from cloud seeding.
