Abstract

Reanalysis of the Colorado River Basin Pilot Proiect data set indicates the -5 °C height, chosen to represent the height of the threshold activation temperature of AgI nuclei, to be a significant criterion for anticipating seeding effects from ground-based seeding systems. In association with criteria of cloud top temperature and wind speed for analyzing the stable or neutral stages of winter orographic storm systems, it separates the sample into cases with and without apparent seeding effect.
