Researchers report detailed observations, using radar and aircraft-mounted instrumentation, of the chain of events following cloud seeding with silver iodide, showing formation of ice crystals within 30 minutes of seeding, growth of ice crystals up to and exceeding 1 mm in diameter, and subsequent precipitation as snow, aiding future investigations of cloud seeding efficacy.
