Abstract The spatially variable advection-correction/analysis procedure introduced in Part I is tested using analytical reflectivity blobs embedded in a solid-body vortex, and Terminal Doppler Weather Radar (TDWR) and Weather Surveillance Radar-1988 Doppler (WSR-88D) data of a tornadic supercell thunderstorm that passed over central Oklahoma on 8 May 2003. In the TDWR tests, plan position indicator (PPI) data at two volume scan times are input to the advection-correction procedure, with PPI data from a third scan time, intermediate between the two input times, that is used to validate the results. The procedure yields analyzed reflectivity fields with lower root-mean-square errors and higher correlation coefficients than those reflectivity fields that were advection corrected with any constant advection speed.
