Abstract:

A cooperative research program among the Utah Division of Water Resources, the National Oceanic and Atmospheric Administration, and the Bureau of Reclamation has investigated targeting of ground-released silver iodide during a winter orographic storm. The cloud seeding material was transported at least 2 km vertically when embedded convection was present. However, ice nuclei concentrations at ambient cloud temperatures were likely too low for effective enhancement except in the highest, coldest cloud turrets.
