Antihail rocket

From Glossary of Meteorology

antihail rocket

A type of cloud seeding device that is fired into a cloud region where it releases a seeding agent.

Such rockets have been launched from the ground and from aircraft. The seeding agent may be generated as smoke from the rocket motor, or it may be part of the rocket payload. Hail suppression programs in Italy, Russia, Yugoslavia, and Switzerland have used rockets to deliver cloud seeding agents into regions of hail-producing thunderstorms where there are large amounts of supercooled liquid water.
