Supercell low-level mesocyclones: Origins of inflow and vorticity

BE Coffer, MD Parker, JM Peters… - Monthly Weather …, 2023 - journals.ametsoc.org
The development and intensification of low-level mesocyclones in supercell thunderstorms
have often been attributed, at least in part, to augmented streamwise vorticity generated …

How well must surface vorticity be organized for tornadogenesis?

MD Parker - Journal of the Atmospheric Sciences, 2023 - journals.ametsoc.org
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 …

Comments on “A Climatology of Cell Mergers with Supercells and Their Association with Mesocyclone Evolution” and “The Influence of Cell Mergers on Supercell …

J Fischer, MD Flournoy, AW Lyza - Monthly Weather Review, 2023 - journals.ametsoc.org
Two recent articles investigated the evolution of supercell mesocyclone intensity during

[HTML][HTML] Comparing polarimetric signatures of proximate pretornadic and nontornadic supercells in similar environments

DJ Healey, MS Van Den Broeke - Weather and Forecasting, 2023 - journals.ametsoc.org
While prior research has shown that characteristics of the supercell environment can

Right-Moving Supercell Tornadogenesis during Interaction with a Left-Moving Supercell's Rear-Flank Outflow

R Edwards, RL Thompson - Weather and Forecasting, 2024 - journals.ametsoc.org
On the local afternoon of 29 May 2012, a long-lived, right-moving (RM) supercell formed
over northwestern Oklahoma and turned roughly southeastward. For> 3 h, as it moved …

Idealized Simulations of a Supercell Interacting with an Urban Area

J Naylor, ME Berry, EG Gosney - Meteorology, 2024 - mdpi.com
Idealized simulations with a cloud-resolving model are conducted to examine the impact of a
