Evaluation of the results of cloud seeding in test projects in mountain areas during the winter season would be speeded by the use of a natural mesoscale unit of observation, the convection band. This creates a requirement for real-time telemetry of observations and remote controlled seeding. The use of the natural sub-unit of a winter storm, the convection band is illustrated by meteorological examples taken from a design study for a Southern Sierra test program. An examination of historical precipitation data showed that with a reasonable assumption as to seeding effects, this method of testing might show statistically significant results in one year; whereas, the conventional seasonal streamflow comparison would require 26 yr, 13 of them seeded and 13 unseeded. Ultimate operational application of these new concepts is explained.
