Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Microphysical characteristics of warm‐rain precipitation that occurred in Fuzhou region during warm seasons of 2022 and 2023 have been investigated by using polarimetric radar data. Results of a modified warm‐rain identification algorithm indicate positive ZDR variation in the liquid layer should be added as a criterion to prevent events ...

Numerical investigation of the influence of topography on simulated downburst wind fields
, 2010 A, dry, non-hydrostatic sub-cloud model is used to simulate an isolated stationary downburst wind event to study the influence topographic features have on the near-ground wind structure of these storms.

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Double‐layer truss bridges are widely used in long‐span crossings due to their high load‐carrying capacity and structural efficiency. However, their complex truss configurations significantly alter the wind field around the deck, posing potential challenges to driving safety and comfort.

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

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.Abstract Longitudinal Lx $\left({L}_{x}\right)$ and lateral Ly $\left({L}_{y}\right)$ integral length scales describe the characteristic horizontal structure of energy‐containing turbulent structures in a flow. The ratio Lx/Ly ${L}_{x}/{L}_{y}$ describes the anisotropy of the structures where Lx/Ly>1 ${L}_{x}/{L}_{y} > 1$ indicates structures elongated

The impact of catastrophic forest blowdown on large wood loads in headwater streams
Earth Surface Processes and Landforms, Volume 50, Issue 15, December 2025.Catastrophic forest blowdown across parts of southeastern Australia in June 2021 substantially increased large wood loads in headwater streams, delivering 88% of the measured wood volume. Wood loads did not correlate to blowdown density but instead were significantly influenced by valley morphology, such that wider valley bottoms had higher wood loads.

Meteorological Applications, Volume 32, Issue 6, November/December 2025.Higher Turbulent Kinetic Energy in YSU indicates strong turbulence in the boundary layer (thick black curved arrows) resulting in the exchange of turbulent fluxes to the upper atmosphere through strong updrafts (Red arrows), making the atmosphere saturated, aiding the realistic prediction of rainfall associated with thunderstorms compared to MYJ and ...
