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.

An analytical downburst model and its application to a moving train wind loading [PDF]
For the first time, a simple analytical model of a downburst has been developed that correctly reproduces the shape of the radial velocity close to the ground, i.e., in a region applicable to trains and low-rise buildings.

CLIMATHUNDERR: experimental database of buoyancy-driven downbursts
Earth System Science DataAbstract. Thunderstorm downbursts are windstorms due to intense negatively-buoyant flows produced beneath cumulonimbus clouds. Their study has recently attracted significant scientific and media attention due to the current and projected impacts of climate change.

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 ...

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 ...
