Radar Detection of Tornadogenesis [PDF]

, 2018
This research compared the basic and polarimetric radar products of non-tornadic and pre-tornadic supercells with the intent of finding a signature which appears to be indicative of tornadogenesis or a lack thereof. Reflectivity (ZHH), spectrum width (σv)

Observations and Analysis of a Tornadic Quasi‐Linear Convective System (QLCS) With Bistatic Weather Radar

Geophysical Research Letters
The deployment of a multistatic radar network in the Oklahoma City metropolitan area in Spring 2024 has allowed for unique observations of several severe weather events.

Mesocyclone Evolution and Tornadogenesis: Some Observations

Monthly Weather Review, 1978
Abstract Updraft mesocyclones in tornado-producing thunderstorms form along convergent and cyclonically sheared boundaries that separate inflow air entering forward and rear storm quadrants. Maximum tangential flow resides in girding wind bands, averaging usually less than 3 km in radius (depending upon the development stage), that strengthen near ...

Analysis of the Cause and Radar Characteristics of a Rare Autumn Strong Tornado Process Occurred in Northern Jiangsu Province

Advances in Meteorology
On September 19, 2023, a rare autumn tornado outbreak, consisting of three successive tornadoes (including one EF3), occurred in northern Jiangsu, China, causing significant damage.

Genesis, Maintenance and Demise of a Simulated Tornado and the Evolution of Its Preceding Descending Reflectivity Core (DRC)

Atmosphere, 2019
This study demonstrates the capability of a cloud model in simulating a real-world tornado using observed radiosonde data that define a homogeneous background. A reasonable simulation of a tornado event in Beijing, China, on 21 July 2012 is obtained. The

Differences in Tropical Cyclone Tornado Activities and Key Tornadic Environments Between China and the United States

Geophysical Research Letters
Tornadic tropical cyclones (TCs) in China occur at a similar frequency to those in the U.S., yet the number of TC tornadoes in China is only 16.5% of that in the U.S.

Dual‐Polarization Phased Array Radar Observations of Quasi‐Linear Convective System Tornadic Mesovortices

Geophysical Research Letters
Quasi‐linear convective system (QLCS) mesovortices produce a non‐trivial fraction of tornadoes across the United States each year. Tornadoes from QLCS mesovortices evolve rapidly on time scales less than that observed by conventional weather radars.

Statistical Characteristics of Dabie‐Vortex‐Associated Tornadogenesis During an 18‐Year Period (2006–2023)

Atmospheric Science Letters
The Dabie vortex (DBV), a mesoscale system frequently generating severe weather in the Yangtze River Basin, exhibits spatial overlap with tornado‐prone regions, yet its tornadic potential remains unexplored.

Using Neural Network Models and Synoptic Circulation Patterns to Project Future Changes in US Tornado Activity

Journal of Geophysical Research: Machine Learning and Computation
Studying the impacts of climate change on tornadoes remains challenging, partly because global climate models (GCMs) struggle to resolve the small‐scale atmospheric phenomena relevant to tornadogenesis.
