Contrasting impacts of two mesoscale cyclones on the South Shetland Islands' glaciers, northern Antarctic Peninsula

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.
This study analyzed the impact of two mesoscale cyclones on the meteorology and glaciology of South Shetland Islands (SSI) glaciers, using in‐situ observations, ERA5 reanalysis data, and high‐resolution weather and glacier mass balance models. Mesoscale cyclones drive temperature drops, heavy snowfall, and strong winds over the SSI, significantly ...

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

Evaluating Bunkers' storm motion of hail-producing supercells and their storm-relative helicity in Germany

Meteorologische Zeitschrift, 2023
This paper presents a statistical analysis of the motion of hail-producing supercells in Germany based on data from a radar-based cell detection and tracking algorithm and a mesocyclone detection algorithm.

Comparative analysis of environmental background and radar characteristics of two tornadoes in Huaibei area on 22 July 2020

暴雨灾害, 2022
On 22 July 2020, tornadoes occurred successively in Suzhou, Anhui and Suqian, Lianyungang and Yancheng in Northern Jiangsu. Era-5 (0.25°×0.25°) hourly reanalysis data and radar echo data are used to analyze and compare the weather background ...

An Automated Method for Depicting Mesocyclone Paths and Intensities [PDF]

Weather and Forecasting, 2013
Abstract The location and intensity of mesocyclone circulations can be tracked in real time by accumulating azimuthal shear values over time at every location of a uniform spatial grid. Azimuthal shear at low (0–3 km AGL) and midlevels (3–6 km AGL) of the atmosphere is computed in a noise-tolerant manner by fitting the Doppler velocity ...

Effects of the urban land use on a severe convective windstorm

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 773, October 2025 Part B.
Numerical simulations with the Weather Research and Forecasting model coupled with the Building Effect Parametrization–Building Energy Model multilayer canopy model were conducted to investigate the impact of urban land use on a severe convective windstorm in Milan, northern Italy, on July 25, 2023.

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

npj 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 ...

A study of the 23 October 2022 southern England damaging MCS

Weather, Volume 80, Issue 10, Page 324-334, October 2025.
During the afternoon of 23 October 2022, a mesoscale convective system (MCS) developed and intensified over the English Channel and tracked north‐northeastward into southern England, producing widespread damaging winds and at least three moderate to strong tornadoes in Hampshire.

Lightning Density and Its Coupled Covariates Within the Continental United States

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract Lightning is a critical climate variable, due to both its significance as a metric of atmospheric thresholding and its significance as a natural hazard. While lightning density is often studied as a marker of local convective dynamics, it is also a player in the larger coupled systems linking the local atmospheric column, the land surface, and
