This page contains results from a partitioning algorithm used to separate convective and non-convective precipitation from gridded radar volumes for the 990126 event. The partitioning technique is a reflectivity texture-based algorithm developed by Tom Rickenbach with characteristics that are similar to Steiner et al. 1995 (click here for a summary of the algorithm's methodology). The algorithm has been applied to all of the 990126 dual Doppler volumes and various analyses have been performed.
Results shown in these plots are composites of convective, stratiform, and total of a given quantitiy for each radar volume displayed as time-height plots (gif format). All the plots show that the MCS was dominated by convective processes prior to ~2140 UTC and by stratiform after this time.
