Three‐Dimensional Lightning Characteristics of Severe Convective Weather in Shanghai

Meteorological Applications, Volume 33, Issue 2, March/April 2026.
Using 2022–2024 ADTD data, this study analyzes 3D lightning in Shanghai's severe convection. Activity peaks in August and afternoon hours, varies by weather type, and concentrates spatially in Pudong and Chongming. Results provide key references for selecting lightning indicators in forecasting and warning systems. ABSTRACT Using ADTD three‐dimensional

A multi‐hazard analysis framework for earthquake‐damaged tall buildings subject to thunderstorm downbursts [PDF]

, 2023
This study develops a generalised multi-hazard analysis framework for evaluating the impact of secondary hazard events on structures that have previously been damaged by major hazardous events. More specifically, the present work investigates the effects

Evaluation of Peak Transmission Line Conductor Reactions Under Downburst Winds Using Optimization and Simplified Approaches

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 ...

Investigating the Microphysical Characteristics and Environmental Influences of Warm‐Rain Precipitation in Fuzhou Region of China

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 ...

The Effect of Variation in the Interlayer Spacing of a Double‐Layer Truss Bridge on the Bridge Deck Wind Environment

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.

Horizontal Anisotropy of Turbulent Fluctuations in Surface and Air Temperatures Over a Flat, Homogeneous Surface

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.

Reconstruction of near-surface tornado wind fields from forest damage [PDF]

, 2010
Tornado intensity is usually inferred from the damage produced. To foster postevent tornado intensity assessments, the authors present a model to reconstruct near-surface wind fields from forest damage patterns. By comparing the structure of observed and
