Mathematical modeling is the most important tool for constructing the theory of concentrated
tornado-like vortices. A review and analysis of computational and theoretical works devoted …

Supercell thunderstorms develop low-level rotation via tilting of environmental horizontal
vorticity (ω h) by the updraft. This rotation induces dynamic lifting that can stretch near …

A 25-member ensemble of relatively high-resolution (75-m horizontal grid spacing)
numerical simulations of tornadic supercell storms is used to obtain insight on their intrinsic …

Abstract The National Severe Storms Laboratory (NSSL) Warn-on-Forecast System (WoFS)
is an experimental real-time rapidly updating convection-allowing ensemble that provides …

The development and intensification of low-level mesocyclones in supercell thunderstorms
have often been attributed, at least in part, to augmented streamwise vorticity generated …

Although much is known about the environmental conditions necessary for supercell
tornadogenesis, the near-ground vorticity dynamics during the tornadogenesis process itself …

Observations of near-surface vertical wind profiles and vertical momentum fluxes obtained
from a Doppler lidar and instrumented towers deployed during VORTEX-SE in the spring of …

In this article, the global climatology of tornadoes and current understanding of the synoptic-
and meso-scale environments of tornadoes and tornado outbreaks are reviewed. The study …

A suite of six idealized supercell simulations is performed in which the surface drag
coefficient C d is varied over a range of values from 0 to 0.05 to represent a variety of water …

This study investigates whether quasi-random surface vertical vorticity is sufficient for
tornadogenesis when combined with an updraft typical of tornadic supercells. The viability of …
