Analysis of Tornadogenesis Failure Using Rapid-Scan Data from the Atmospheric Imaging Radar [PDF]

, 2019
Tornadogenesis in supercell thunderstorms has been a heavily studied topic by the atmospheric science community for several decades. However, the reasons why some supercells produce tornadoes, while others in similar environments and with similar ...

A Statistical Analysis of Surface Roughness Influences on Tornadogenesis and Tornado Decay within the Southeastern United States [PDF]

, 2023
As tornadic activity increases in the Southeastern United States (Agee et al. 2016), it becomes imperative to investigate tornadic activity in this region. Given that patterns of land cover greatly differ between the Southeast and the traditional Tornado

Electrical Role for Severe Storm Tornadogenesis (and Modification) [PDF]

Journal of Climatology & Weather Forecasting, 2015
Damage from severe storms, particularly those involving significant lightning is increasing in the US. and abroad; and, increasingly, focus is on an electrical role for lightning in intra-cloud (IC) tornadogenesis. In the present report, emphasis is given to severe storm observations and especially to model descriptions relating to the subject.

Intensification of the low-level updraft in supercells preceding tornadogenesis [PDF]

, 2017
As described by R. Davies-Jones, tornadogenesis is a three step process. A mesocyclone forms aloft, followed by the development of near ground rotation. The concentration of this near ground rotation within outflow air can then lead to tornadogenesis.

Tornadic Storm over the Foothills of Central Nepal Himalaya

Meteorology
On the evening of 31 March 2019, Parsa and Bara Districts in central Nepal were severely hit by a wind storm which was the first documented tornadic incidence in Nepal.In this paper, we investigate the background of the tornado formation via numerical ...

Developing an Object‐Based Climatology of Tornadic Storms Over the United States Using Machine Learning and Radar Reanalysis

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Tornado climatologies over the contiguous United States have traditionally relied on report‐based data sets, which are subject to biases related to population density, time of day, and evolving observational practices. This study presents an object‐based machine learning framework for constructing a tornado climatology using storm cluster data

Clustering of Right‐Moving Tornadic Supercell Proximity Sounding Profiles Using an Explainable Framework

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract This study demonstrates an explainable machine learning framework for explicitly selecting important environmental features that determine clusters of right‐moving tornadic supercells. Although previous studies have clustered and analyzed proximity sounding profiles associated with tornadic right‐moving supercells, few have identified key ...

ERA5‐Based Convective Environments Favorable for Tornadoes in Southern China

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Tornado occurrences vary significantly across regions in the globe, attributable in part to variations in regional climate and topography. This study analyzes the long‐term convective environments associated with tornadoes in southern China, a region previously identified as having the most favorable meteorological conditions for tornadoes ...

A Clarification of Vortex Breakdown and Tornadogenesis

Monthly Weather Review, 2000
Recent and past observations of a central downdraft within a mesocyclone have been misinterpreted as evidence of vortex breakdown on the mesocyclone scale. In this note, the literature is reviewed and model examples are provided in order to demonstrate that the mesocyclone dynamics likely precludes mesocyclonic vortex breakdown.
