Simulated Convection in Tornadic and Non-Tornadic Environments from Collaborative Field Efforts in the SE U.S.

High-resolution numerical simulations are a valuable tool at identifying the dynamics behind supercell and tornado processes. Many studies have focused on analyzing these relationships and dynamics in environments from Great Plains convective events. Yet it has been well established that climatology of storm environments in the Southeast U.S. differ significantly compared to their Plains counterparts. Therefore a relative knowledge gap exists between the dynamical process knowledge in Great Plains compared to Southeast U.S. supercells. Cloud Model 1 is used in conjunction with radiosonde composites from recent collaborative field campaigns in the Southeast U.S. to analyze these processes. Experiments in this work consist of ensemble-based approaches to identify differences between the resulting supercells in the non-tornadic and tornadic composite kinematic environments and sensitivity tests to the low- and mid-level wind profile; the largest difference between the two composite profiles. The resulting analysis will include a discussion of storm-scale differences and how these environments support or prevent vortex-genesis. This includes a comprehensive look into the updraft characteristics that result from these environments, low-level accelerations, and associated decomposed pressure perturbations. Preliminary results show environments primed to stretch vertical vorticity given the low-level (~1 km AGL) vertical accelerations and a horizontal displacement between the areas of maximum vertical vorticity and the main low and mid-level updraft likely hindering vortex production in the simulated tornadic and nontornadic storms.
