Some call them mosaics, I call them composites. In this talk, I will discuss past, ongoing, and planned research activities using three-dimensional multi-radar composites of single- and dual-polarization (or polarimetric) NEXRAD WSR-88D observations produced in my research group. In particular, I will provide a brief overview of the composting process and discuss three main areas of research that I and my students have been pursuing: 1) composite-based algorithm development, 2) tropopause-penetrating convection, and 3) microphysical characteristics of Mesoscale Convective Systems (MCSs). I will present examples from the application of a new echo top based storm tracking algorithm, the application of a novel storm classification algorithm that objectively stratifies radar echo into 7 categories (deep convection, shallow convection, convective updraft, stratiform rain, transitional anvil, thick anvil, and thin anvil), and the analysis of tropopause-penetrating convection. Cases used for these examples include supercells, MCSs, and a storm reaching an altitude of 20 km. If you like rainbow color tables, movies, satellite imagery, weak echo regions, ZDR columns, KDP columns, or mediocre illustrations then you are bound to enjoy at least a portion of my presentation.
