The Bayesian sinking in Porticello: a predictable convective windstorm?

Weather, Volume 80, Issue 11, Page 365-373, November 2025.
The meteorological phenomenon that led to the Bayesian yacht sinking in Sicily at 0206 utc on 19 August 2024 is here investigated. A thunderstorm occurred during the sinking, but uncertainties exist regarding whether a waterspout or a downburst affected the ship. An in‐depth analysis of available observations highlighted that the ship was likely struck

Full-Cloud Numerical Simulation of a Translating Isolated Thunderstorm Producing a Wet Downburst

Atmosphere
A real downburst event that occurred in the city of Genoa, Italy, on 14 August 2018, is simulated using the full-cloud model CM1. The initiation of the thunderstorm cell is triggered through the warm bubble technique, which allows simulating the whole ...

High‐Spatial Resolution Space‐Based Observations in the Upper Troposphere and Upper Mesosphere of Wavelike Features Produced by Hurricane Ian

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract A new high‐spatial resolution camera on the International Space Station used OH nightglow in the H‐band to image the ground at an ∼ ${\sim} $70 m pixel footprint over an ∼ ${\sim} $280 km swath and maintained this resolution during its 1.5 s exposure.

Characteristics of Rainfall in Wind Field of a Downburst and Its Effects on Motion of High-Voltage Transmission Line

Shock and Vibration, 2017
Despite most weather-related failures of high-voltage transmission lines (HVTLs) being attributed to the downbursts accompanied by heavy rainfall, research works mainly focused on the behaviors of the high-voltage transmission tower-line structures under

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.

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.

Evaluation of Monin‐Obukhov Similarity Theory Wind Profiles in Convective Storm Environments and Cold Pools at the ARM Southern Great Plains Atmospheric Observatory

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 18, 28 September 2025.
Abstract Monin‐Obukhov similarity theory (MOST) is widely used in numerical weather prediction to model surface fluxes of momentum, heat, and water vapor. However, MOST is based on assumptions of steady state and horizontally homogeneous turbulence that can lead to prediction errors in and around convective storms.

Wind Field Characteristics of the 13 June 2014 Downburst Event in Beijing Based on Meteorological Tower Records

Atmosphere
Understanding the characteristics of downburst wind fields is crucial for studying structural resistance to downbursts. Based on measured data from the 325 m meteorological tower in Beijing, this paper investigates the spatiotemporal evolution of mean ...

Sensitivity of inflow turbulence uncertainty on wind pressure on high‐rise buildings using large eddy simulations

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 22, Page 3430-3450, 9 September 2025.
Abstract Large eddy simulations (LES) can aid the prediction of wind loading on buildings, provided that representative inflow turbulence properties are prescribed. This study conducts LES to assess the sensitivity of the mean, root mean square (rms) fluctuation, and peak pressure coefficients (Cp) on building surfaces to the uncertainties in the ...

Observations of a frontal–trough merger over a wildfire, Queensland, Australia

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 771, July 2025 Part B.
Observations are presented of the meteorology of a frontal–trough merger in subtropical Australia which impacted a wildfire. An elevated nocturnal mixed layer above approx. 2500 m with increasing moisture with height was identified as the source of instability that resulted in the formation of elevated storms along a 300‐km frontal–trough boundary ...
