Tornadogenesis And Tornadogenesis Failure In Numerically Simulated Supercells
… striking difference between the tornadic and nontornadic simulations was that the tornadic simulations produced more negative vertical vorticity in descending parcels, and that the parcels that entered the low-level circulation rose to higher altitudes than the parcels in the nontornadic …

Thermodynamic, kinematic, and radar parameters of isolated tornadoes with and without NWS warning
… before formation, as well as between nearby nontornadic cells. The results revealed shear, divergence and convergence as significantly different between the events. Although azimuthal shear resulted as statistically significant, it does not perform well when deciphering between tornadic and …

Impacts of cold pool strength on tornado production in quasi-linear convective systems
… line vertical wind shear for 94 tornadic and nontornadic QLCSs in the central and eastern United States from 2017–2022. Cold pool strength was quantified by the virtual potential temperature perturbation from the base state using 1-minute observations from Automated Surface Observing System …

Assessing the impacts of microphysical and environmental controls on simulated supercell storms
… tornadic supercells from those that will produce nontornadic supercells. To address the goals, a suite of experiments were performed with a numerical model where the Convective Available Potential Energy (CAPE), Lifted Condensation Level (LCL), and low level wind shear are independently perturbed. …

Insights into tornadogenesis and tornado dynamics from idealized simulations
… can cause a bifurcation between the tornadic and nontornadic cases, demonstrating the nonlinearity of tornadogenesis. The relative importance of the updraft and cold pool intensities depends on the position within the 2D spectrum spanned by the two parameters, with e.g., intensification of the …
