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 refined empirical model of steady-state downburst based on high-resolution wind speed data obtained from wind tunnel tests

Advances in Wind Engineering
A slice of research pertinent to the analytical or empirical models of downburst winds was available, but the current validation was usually based on sampled wind velocities at several typical positions in the experimental measurements rather than the ...

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.

Numerical Modeling of Thunderstorm Downbursts and Downburst Lines [PDF]

, 2010
Large eddy simulations have been used to compare the near surface outflow of the commonly used transient impinging jet to that of the physically realistic cooling source downburst model. This has shown that the transient impinging jet is incapable of capturing the buoyancy driven features of an actual downburst, due to its non-physical forcing ...

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 ...

Simulation of the Flow Field Characteristics of a Downburst [PDF]

, 2007
Wind load on a structure is usually investigated in turbulent boundary layer flow simulated in a boundary layer wind tunnel. However, the strong wind that causes damages on structures is usually transient wind, for instance, downburst wind, whose statistics are different with the general atmospheric boundary layer.

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 ...

Characteristic Analysis of the Downburst in Greely, Colorado on 30 July 2017 Using WPEA Method and X-Band Radar Observations

Atmosphere, 2018
As a manifestation of low-altitude wind shear, a downburst is a localized, strong downdraft that can lead to disastrous wind on the ground surface.

Added Value of Environmental Variables for Satellite Precipitation Retrieval: A Temporal Coevolution Perspective and a Machine Learning Integration Assessment

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Satellite precipitation retrieval is inherently an underdetermined inverse problem where additional physical constraints could substantially enhance accuracy. While previous studies have explored static (pixel‐based/spatial‐context‐based) environmental variables at discrete satellite observation times, their temporal dynamic information ...
