Dispersal of Supercooled Stratus Clouds by Silver Iodide Seeding.
Abstract
During February 1977, a field program was conducted in northern Michigan to determine the feasibility of using silver iodide flares to make clearings in supercooled stratus decks over pre-selected ground locations. Targeting of the clearings was always possible if an accurate measurement of the wind at cloud height were available. The temperature in the upper portion of the cloud is apparently the critical meteorological parameter. On no occasion was a clearing effected when the cloud-top temperature was -6 degrees C or warmer; however clearing did occur when cloud base temperature was as warm as -3 degrees C. (Author)
