16. ABSTRACT

M
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
eli.gible storms.

Past use of seeding in Colorado for drought relief is discussed.
The theory of winter seeding, past field experiments in Colorado
and variability in Colorado's snowpack are discussed briefly in the
Appendices.
