Abstract
A validation of an improved radar reflectivity partitioning scheme was performed using radar data collected for three separate precipitation systems in Central Texas. The improved algorithm was compared to a previously accepted method. Validation was performed using separate convective and stratiform mean vertical reflectivity profiles and mean vertical velocity profiles derived from dual-Doppler velocity data. The results were further validated through the use of convective and stratiform reflectivity and vertical velocity contour frequency by altitude diagrams (CFAD). As a final check, frequency distributions of reflectivity lapse rates in the mixed phase region were also examined. The results show that the new algorithm brings us a step closer in properly partitioning radar reflectivity data into its convective and stratiform parts. However, a few more modifications are needed in order to make it a more functional algorithm.
