Mass mortality of saguaros (Carnegiea gigantea) from windthrow: A rare, demographic disturbance in a desert ecosystem

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Windthrow is a significant disturbance in many forests globally during which strong winds damage trees or other large flora, yet its role in arid ecosystems remains largely understudied. The saguaro cactus (Carnegiea gigantea), a keystone species of the Sonoran Desert, is a long‐lived, massive succulent whose demography is primarily thought to

A New Approach to Nowcasting Thunderstorm Gusts Based on a Spatiotemporal Decoupling Architecture and Multi‐Scale Feature Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract Accurate short‐term forecasting of thunderstorm gusts remains a major challenge in the Beijing–Tianjin–Hebei region due to limited temporal resolution, the lack of vertical velocity and thermodynamic data, and the difficulty of coupling multi‐scale features.

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

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
