Excerpt: Can cloud seeding -- dispersing particles into the air with the aim of increasing precipitation -- increase snowfall? This week, a team of researchers began a cloud-seeding project in southwestern Idaho to answer that question. Cloud seeding is a process by which artificial ice nuclei, such as silver iodide particles, are released into clouds, either from the air or via ground-based generators. The Idaho project, funded by the National Science Foundation (NSF) and dubbed SNOWIE (Seeded and Natural Orographic Wintertime Clouds -- the Idaho Experiment), will run from January 7 to March 17 in and around the Payette Basin, 50 miles north of Boise. "Scientists are still uncertain about cloud seeding for increasing precipitation, despite ongoing operations around the globe," says Nick Anderson, program director in NSF's Division of Atmospheric and Geospace Sciences. "SNOWIE is the most comprehensive study to date on cloud seeding in winter." ...Snow from winter storms develops when ice crystals form on dust and other particles known as "ice nuclei." In many storms, the lack of natural ice nuclei at warmer temperatures results in less precipitation....
