Comparison of the Potential of Cloud Seeding to Enhance Mountain Snowack in Colorado during Dry, Normal and Wet Winters

摘要

This study compares the potential of cloud seeding to enhance mountain snowpack in Colorado during dry, normal and wet winters. Seedable storms are identified from 13 winters of interpolated rawinsonde observations. While a few more seedable storms are identified in the wet than in the dry winters, this difference is not significant statistically; neither is the difference in percentage increases in the moisture content of snow expected from seeding all eligible storms. Past use of seeding in Colorado for drought relief is discussed.
