Rain making

From Glossary of Meteorology

rain making

Popular term applied to all activities designed to increase, through any artificial means, the amount of precipitation released from a cloud.

The techniques of cloud seeding have been studied carefully and extensively, especially since V. J. Schaefer's discovery of the effect of dry ice on supercooled clouds.
