Abstract

The aftermath of the 1972 Rapid City flood included a controversy over the propriety of cloud seeding on the day of the flood and a lawsuit against the U.S. Government. Preparation of the defense against the suit involved analyses of hourly rainfall accumulations, radar data from the seeded clouds, and possible microphysical and dynamic effects of seeding clouds with powdered sodium chloride (salt). Recent developments in numerical modeling offer some hope of improved understanding of the storm. However, mesoscale systems remain somewhat unpredictable, and realization of this fact has inhibited research dealing with the deliberate modification of large convective clouds.
