Summary

Summer cloud systems in the arid and mountainous region around Tucson, Arizona, are predominantly convective in nature. Extensive radar observations of these systems have been made by the Institute of Atmospheric Physics, University of Arizona, using height-finding radar. A study of the level of formation of radar echoes, based on data collected during the summer of 1956, indicates that an all-water process, as well as one involving the ice phase, was effective in initiating precipitation. Moreover there appeared important day-to-day differences in the efficiency of the water mechanism.
