Analysis and Forecast of a Tornadic Thunderstorm Using Multiple Doppler Radar Data, 3DVAR, and ARPS Model

Advances in Meteorology, 2013
A three-dimensional variational (3DVAR) assimilation technique developed for a convective-scale NWP model—advanced regional prediction system (ARPS)—is used to analyze the 8 May 2003, Moore/Midwest City, Oklahoma tornadic supercell thunderstorm. Previous

Structure of a shear-line polar low [PDF]

, 2017
During March 2013 a series of polar lows originated in a high-vorticity (>10−3 s−1) shear zone that was associated with a prolonged marine cold-air outbreak over the Norwegian Sea.

Revealing Key Dynamical Mechanisms of a Severe Supercell Within a QLCS Using Rapid Update 4DVar Assimilation of C‐Band Phased Array Weather Radar Data

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract We investigate the evolution of a supercell storm within a quasi‐linear convective system (QLCS) that occurred in the Beijing area on 12 June 2022. Using high spatiotemporal resolution observations from a C‐band phased array radar (PAR), assimilated into a four‐dimensional variational data assimilation system, we primarily analyze dynamical ...

Inter-Zone Differences of Convective Development in a Convection Outbreak Event over Southeastern Coast of China: An Observational Analysis

Remote Sensing, 2021
Among the densely-populated coastal areas of China, the southeastern coast has received less attention in convective development despite having been suffering from significantly increasing thunderstorm activities.

Numerical Simulation of a Tornado Generating Supercell [PDF]

, 2012
The development of tornadoes from a tornado generating supercell is investigated with a large eddy simulation weather model. Numerical simulations are initialized with a sounding representing the environment of a tornado producing supercell that affected

Two archetypes of tornadic quasi‐linear convective systems in the United Kingdom: Relevance of horizontal shearing instability to vortexgenesis and maintenance

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 770, July 2025 Part A.
Two archetypes of tornadic quasi‐linear convective systems with and without horizontal shearing instability. Modeled surface precipitation rates (mm ·hr$$ \cdotp \mathrm{hr} $$ −1$$ {}^{-1} $$; colored) and absolute vorticity (contours every 3×10−3$$ 3\times 1{0}^{-3} $$ s −1$$ {}^{-1} $$; dashed when negative) after vortexgenesis from the model domain.

Mesocyclone Evolution and Differences between Isolated and Embedded Supercells

Atmospheric and Climate Sciences, 2013
A total of 61 supercells with mesocyclones lasting for at least 6 volume scans were investigated. These storm parameters and mesocyclone parameters were counted and compared to determine the salient differences between isolated supercells and embedded supercells in different regions.

On the efficiency of stratospheric gravity wave production from mid‐latitude convective systems: 2D versus 3D dynamics

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 770, July 2025 Part A.
Due to greater convective organization, our results indicate higher efficiency of gravity wave production in two‐dimensional systems than in three‐dimensional systems. By analyzing the domain‐averaged entrainment rate, we identified a strong correlation between convective organization and gravity wave (GW) production efficiency, with implications for ...
