Wyoming research indicates cloud seeding works

Cheyenne, WY (AP) - Scientists are encouraged by preliminary research that shows seeding clouds enhanced the amount of snow in winter storms over mountain ranges in southern Wyoming.

University of Wyoming atmospheric science professor Bart Geerts says there's overwhelming evidence that cloud seeding does increase the amount of snow produced in clouds.

Geerts has led a research effort in conjunction with a nearly decade-long, $13 million project by the state of Wyoming to see if cloud seeding can increase snowfall in several mountain ranges.

Cloud seeding involves injecting silver iodide into clouds either from aircraft or from generators on the ground. The practice is used in many areas, but it's uncertain whether it really works.

The National Science Foundation says the research by Geerts is promising and should encourage further cloud-seeding research.
