Abstract : Vertical profiles of the total precipitation in the area scanned by a radar were obtained for the first time. Profiles for summer shower situations commonly show an accumulation of precipitation aloft. Its height is observed to increase with the available energy of convection. This observation was combined with calcucculations by oto other researchers to give a three-fold relation among mean updraught speed, heigiight of accumulation and energy of convection. Profiles for continuous rain are quite distinct from those of showers, generally showing the greatest amount of precipitation at the base of the storm. Profiles form a useful digest of the radar data for the synoptic meteorologist. The essential data can be reduced to small arrays of digits, which are economically transmitted and readily interpreted to give insight into the precipitation pattern and the accompanying convection.
