The mission of the North American Weather Modification Council (NAWMC) is to advance the proper use of weather modification technologies through education, promotion and research. The Council serves as a forum for the exchange of information on weather modification issues; to promote the effective use of these technologies to enhance precipitation, suppress damaging hail, and mitigate fog; and to advance research and development activities to increase scientific knowledge about weather modification capabilities.

Learn about Cloud Seeding
The NAWMC has developed three brochures on the basics of cloud seeding. The brochures cover the science of cold season and warm season operations and its relation to the climate and environment.
What is Weather Modification?
Weather modification (also known as cloud seeding) is an environmentally friendly way to generate more precipitation from clouds in the form of rain or snow. It works through the introduction of tiny particles ("seeds") that create additional droplets or ice, thereby accelerating the precipitation process and improving the cloud's efficiency. Cloud seeding is also used to reduce hail damage and eliminate fog. This well-established technology has been in use since the 1940s in dozens of countries around the world.
