Frontiers in Built Environment, 2019 Transmission line structures, though designed per code provisions, have suffered several failures worldwide in the past. As reported in the body of the available literature, more than 80% of those failures are due to severe localized wind events such as ...

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 ...

An observational study of a circular gust front over the Yangtze Delta, China
Weather, Volume 80, Issue 11, Page 387-394, November 2025.Concentric gust fronts are formed when a thunderstorm’s downdraft reaches the ground and the outflow from the cold pool spreads uniformly outwards into the surrounding warm and humid air mass. Observational evidence presented here show the case of narrow‐band echoes forming a ring around a thunderstorm.

First reported case of thunderstorm asthma in Israel [PDF]
Natural Hazards and Earth System Sciences, 2019 We report on the first recorded case of thunderstorm asthma in Israel, which occurred during an exceptionally strong eastern Mediterranean multicell thunderstorm on 25 October 2015. The storms were accompanied by intensive lightning activity, severe hail,

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
