A Radar-Based Investigation of Velocity Distribution Reorganization and Coherent Structure Development Prior to Tornadogenesis

This project investigates whether measurable changes in Doppler velocity distribution entropy and localization occur prior to tornadogenesis in supercell thunderstorms.

Surface thermodynamic characteristics of hook echoes and rear-flank downdrafts, with implications for tornado genesis and maintenance.

, 2000
Since its first documentation in 1953, the "hook echo" has been perhaps the best-recognized radar feature of supercell storms. Hook echoes have been associated with a region of subsiding air to the rear of both tornadic and non-tornadic supercells. Today

, 2005
This study presents an overview of lightning formation and the correlations seen with soil moisture slope along with potential of tornadic thunderstorms.

Important Factors for Tornadogenesis as Revealed by High-Resolution Ensemble Forecasts of the Tsukuba Supercell Tornado of 6 May 2012 in Japan

Monthly Weather Review, 2018
To identify important factors for supercell tornadogenesis, 33-member ensemble forecasts of the supercell tornado that struck the city of Tsukuba, Japan, on 6 May 2012 were conducted using a mesoscale numerical model with a 50-m horizontal grid.

Madden–Julian Oscillation–Induced Suppression of Northeast Pacific Convection Increases U.S. Tornadogenesis

Journal of Climate, 2020
This study investigates the impact of the Madden-Julian oscillation (MJO) on U.S. tornadogenesis using atmospheric reanalysis and model experiments. Our analysis shows that the impact of MJO on U.S.

Vortex Gas Models for Tornadogenesis and Maintenance

2022
Tornadogenesis is thought to be influenced by processes related to the generation of vorticity in the forward and rear flank downdrafts, as well as their interaction with the boundary layer. Our goal is to show that vortex gas models are an appropriate tool to describe the processes of tornadogenesis and maintenance.
