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

open access: yesAdvances in Meteorology, Volume 2026, Issue 1, 2026.
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. This study presents a comprehensive analysis of this event using multisource data, including Doppler radar, ERA5 reanalysis, and surface observations.

Three‐Dimensional Wind Field Retrieval From Multiple Weather Radars: Some Observational Results

open access: yesAdvances in Meteorology, Volume 2026, Issue 1, 2026.
With the increasing number of Doppler weather radars in Hong Kong and the surrounding Greater Bay Area (GBA), three‐dimensional (3D) wind fields retrieved from multi‐radar Doppler velocities have been put into real‐time trial operation since spring 2025.

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

open access: yesAdvances 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

Antarctic mesocyclone regimes from satellite and conventional data [PDF]

open access: yesTellus A: Dynamic Meteorology and Oceanography, 1992
Mesoscale vortices in the Antarctic, poleward of 50°S, are examined in the synoptic context for the Ross Sea sector (100°E eastward to 80°W) for transition and winter months of 1988, using DMSP (Defense Meteorological Satellite Program) thermal infrared (TIR) images.

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

open access: yesGeophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract 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. In this study, a well‐calibrated, dual‐polarization phased array radar (PAR) is used to examine

Hailstorms and rainstorms versus supercells—a regional analysis of convective storm types in the Alpine region

open access: yesnpj Climate and Atmospheric Science, 2023
The behaviour of severe thunderstorms, particularly supercells, in complex terrain is still poorly understood. Utilising 6 years of radar-, lightning- and radiosounding-based thunderstorm data in the domain of the Swiss radar network, we study different ...
