Understanding tornado intensity in supercells and quasi-linear convective systems
… storms capable of producing strong to violent tornadoes remains a focus of severe weather research due to their potentially significant impacts on life and property. The three parts of this dissertation contribute to new understanding of the controls on, and operational anticipation of, such …

Improving the anticipation of potential tornado intensity across different time scales
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2025-02-04 without embargo terms

The observed relationship between tornado intensity and pretornadic mesocyclone characteristics and environments
… support of their hypothesis that wide, intense tornadoes should form more readily out of wide, rotating updrafts. Observational data were used herein to test the generality of this hypothesis, especially to tornado-bearing convective morphologies such as quasi-linear convective systems (QLCSs), …

Controls of updraft size, cold pool characteristics, and potential tornado intensity in supercell thunderstorms
… lead to the formation of particularly intense tornadoes are modulated by updraft width. Specifically, a simple hypothesis is proposed that larger, more intense tornadoes should more readily form from wider rotating updrafts. This hypothesis is tested using idealized simulations, which reveal …

Estimating midlevel updraft characteristics and severe weather intensity through the lens of overshooting tops
… quantify midtropospheric updraft area as well as intensity and vertical mass flux. Using radar-retrieved updraft area and corresponding calculations, a scaling factor and simple approach was used to estimate distributions of updraft core radii using OTs during the three cases. The estimated …

Spatial Patterns and Variations of Tornado Damage as Related to Southeastern Appalachian Forests and Terrain from the Franklin County, Virginia EF-3 Tornado
Strong tornadoes have impacted the central Appalachian Mountains multiple times in recent years. The topography of this region leads to unique spatial patterns of tornado damage as the tornado vortices pass over ridges in forested areas, and this damage can be detected with vegetation indices …

Near-surface tornado wind field estimation using damage patterns
Tornadoes are considered the most violent and dangerous wind hazards and are emerging as a major public concern, causing a significant amount of property loss and casualties in the past decades. In response, the engineering community in the United States is implementing tornado-based design in …
