Case Studies on Convective Storms / Case Study 8, 9 August 1974: First Echo Case

The winds aloft and the direction of motion of the storm nearly coincided with a line between the radar and the storm, and the radar data were rather symmetrical about this line. This, combined with the simplicity of the structure of the storm, provided ideal circumstances for an interpretation of the internal motions in spite of the handicap that only single-Doppler data were available.

This interpretation was accomplished using a three dimensional simulation of the storm. The deduced internal motions appear to provide a means whereby ice particles of precipitation size may reenter the updraft at low levels.
