Our Mission

Enabling persons, political entities, and other organizations to make informed decisions about the application of weather modification technologies, to provide for adequate water supplies, and reduced natural weather hazards.

Our Vision

HISTORY

The Weather Modification Association was organized in 1950 to cultivate a better understanding of weather modification techniques, impacts, and expectations among program sponsors, program operators, and the scientific community, and to promote ethical professional conduct and a free exchange of information.

“Free exchange of accurate information regarding the efficacy, safety, methodology and cost-effectiveness of weather modification activities.”

WHAT WE DO

Weather modification can be both planned, as is the case in cloud seeding (cloud modification), or inadvertent, for example, when pollution affects visibility. Planned (deliberate) weather modification is also commonly known as cloud seeding, cloud modification, and atmospheric water management. The WMA fields a wide variety of inquiries, from domestic and foreign governmental agencies, to the student doing a report for the classroom.
