Vertical profiles of radar parameters in heavy rain events resulting from elevated and surface based convection

Elevated convection over the central United States is thoroughly examined through the analysis of level-II dual-polarization radar data from NWS WSR-88Ds. Analysis techniques include the use of standard methods such as CAPPIs (Constant Altitude Plan Position Indicator) and three dimensional cross sections and less typical methods such as storm-cell identification and tracking as well as vertical profiles with respect to radar detected variables. In particular, this research presents a study of patterns of radar variables such as reflectivity, divergence (convergence), specific differential phase (KDP), differential reflectivity (ZDR), and hydrometeor classification with respect to each of the aforementioned analysis techniques in elevated convection in contrast to cases of surface-based convection. These methods are used to better understand the lifecycle of an elevated thunderstorm with regards to its shape, orientation, precipitation structure, drop size distribution, etc. Furthermore, the Doppler velocity derived divergence/convergence product examined with height is of particular interest within the low levels of an elevated thunderstorm given the thunderstorms elevated nature with its inflow rooted above the surface layer.
