Summary

Instrumentation which has been developed recently presents radar echoes from precipitation in the form of range-corrected signal-intensity contours, thus making it possible to observe in a quantitative manner the smaller-scale features within the precipitation areas which appear on the normal radar-scope presentation. This paper presents some preliminary results of the analysis of such data for two types of storms: warm-front type rain in an unstable atmosphere, and showers associated with instability lines. Dimensions, durations and motions of areas of heavy rain and of individual shower cells are considered in an attempt to determine the scales of atmospheric circulations which are particularly significant in the production of precipitation.
