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.

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,

Influence of Convectively Driven Flows in the Course of a Large Fire in Portugal: The Case of Pedrógão Grande

Atmosphere, 2022
The influence of a mesoscale convective system (MCS) in the evolution of two wildfires that started during the afternoon of 17 June 2017 in Pedrógão Grande, Central Portugal is discussed and analysed using weather radar data, weather stations, video ...

Evaluating the Impact of the Planetary Boundary Layer on Dynamics of Urban Thunderstorms Over the Eastern Indian Region

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 ...

New interpretations targeting European atmospheric circulation patterns and their association with climate-related hazard events in Romania. [PDF]

Aerul şi Apa: Componente ale Mediului
Atmospheric circulation exerts a dominant influence on the occurrence, intensity, and spatial distribution of climate-related hazards in Romania. This study investigates the relationship between major European synoptic-scale circulation patterns, such as

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.

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

High‐Spatial Resolution Space‐Based Observations in the Upper Troposphere and Upper Mesosphere of Wavelike Features Produced by Hurricane Ian

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract A new high‐spatial resolution camera on the International Space Station used OH nightglow in the H‐band to image the ground at an ∼ ${\sim} $70 m pixel footprint over an ∼ ${\sim} $280 km swath and maintained this resolution during its 1.5 s exposure.

Post-disaster investigations of damage feature of buildings and structures due to several local strong winds in China during 2021–2024

Advances in Wind Engineering
Local strong winds such as tornadoes and downbursts are rare in terms of measured wind speed data due to their rapid formation and strong destructive power.
