The effects of entrainment in the developing and rotating stages of supercell thunderstorms
… to investigating the entrainment into developing thunderstorms growing in environments with strong vertical wind shear, or to how rotating updrafts in some thunderstorms (i.e. supercells; produced in environments with specific characteristics of the vertical wind shear) might alter the amount of …

Controls of updraft size, cold pool characteristics, and potential tornado intensity in supercell thunderstorms
… parameterization schemes. Here, the structure of supercell updraft width and its connection to attendant cold pool characteristics are examined using idealized simulations. This study finds that, within a supercell storm mode, updraft width is strongly dependent on environmental vertical wind …

Terrain and Landcover Effects of the Southern Appalachian Mountains on the Low-Level Rotational Wind Fields of Supercell Thunderstorms
… for smaller-scale severe weather phenomena like supercells and tornadoes. This study examines how complex terrain may have influenced the rotational low-level wind fields of fourteen supercell thunderstorms in the Appalachians. The terrain variables include elevation, land cover, slope, and …

The numerical simulation of non-supercell tornadogenesis
Non-supercell tornado is a name given to a class of tornadoes which occur with deep moist convection not displaying the strong mid-level rotation found in supercell thunderstorms. In recent years the severe storms community has acknowledged that a significant portion of the small tornadoes …

The observed relationship between tornado intensity and pretornadic mesocyclone characteristics and environments
… (2017, JAS) used idealized model simulations of supercell thunderstorms to demonstrate 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 …

The impact of midlevel shear vector orientation on the longevity of and streamwise vorticity current formation within simulated supercells with freeslip and semi-slip lower boundaries
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-12-04 without embargo terms

Assessing the impacts of microphysical and environmental controls on simulated supercell storms
Supercell thunderstorms are some of the most dangerous single-cell storms on the planet. These storms produce many hazards to life and property, including tornadoes, floods, damaging straightline winds, strong updrafts and downdrafts, and lightning. Although these hazards are not unique to …
