The WMA – Promoting weather modification for beneficial uses

seed This is a site that promotes companies and weather modification research.


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

The Weather Modification Association (WMA) 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. 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 cloud seeding, cloud modification, and atmospheric water management. Have a look at this map of all the weather modifcation research centres in USA: See what the companies do, have a sniff. Heres a couple ya lazy :   SeedingEffects An obvious hole in a stratus deck due to cloud seeding with aircraft, using dry ice as a seeding agent. This is an example of cold cloud seeding, where supercooled cloud droplets are converted into ice crystals, which then precipitate out of the cloud deck.
