Although no cloud seeding was done, the hail researchers refined and developed radar techniques and tested instruments for probing hailstorms, including a new instrument that measures the size and amount of hail, the disdrometer. Analyzing data has provided new knowledge of hailstorm types based on number of updraft cells. The possibility of improper seeding techniques leading to increased hail is discussed, and the writer postulates that at least three more years of cloud seeding experiments would be needed to gauge the possibility of hail suppression.
