He notes that no cloud seeding had been done that summer, but that researchers are on standby for the right sort of storms. Only a few storms were planned to be seeded that summer, and so far they had been testing new research systems and observing unseeded hailstorms with radar, weather balloons, and aircraft. Full-scale research operations would be conducted over the subsequent several years to study the physics and dynamics of hailstorms and test seeding techniques to reduce the hailstorms' destructive forces. Silver iodide was to be used to convert the storm's moisture into smaller hailstones or simply rain. Show less
