Part of: Planning Now for Irrigation and Drainage in the 21st Century


The effect on convective cells of randomized seeding for dynamic effects in the Southwest Cooperative Program is addressed. Analysis of three-dimensional, volume-scan, radar data using sophisticated tracking software indicates that silver iodide (AgI) seeding increased the area, durations and rain volumes from the cells. The apparent effect on rainfall was over 100%. These and other results are discussed.
