CFD Simulation of Curved-Roof Subjected to Thunderstorm Downburst
, 2011 Thunderstorm downburst is a sort of outburst strong wind on or near the ground, and its wind field characteristics are significantly different from boundary layer winds. The study on its effect on the structures was relatively rare, nevertheless numerous

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.

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.

Computational simulation of thunderstorm downbursts and associated wind turbine loads
, 2013 textWind turbines operate in a constantly changing wind environment. This requires modeling and simulation of extreme events in which the wind turbine operates and a study of associated turbine loads as part of the design practice and/or site assessment.

Effect of complex orography on numerical simulations of a downburst event in Spain [PDF]
PRE2020-092343A downburst is a localized and intense downdraft of air that descends quickly from the middle troposphere and reaches the Earth's surface. It is frequently originated by a thunderstorm or a supercell.

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 ...

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 ...
