A Simulation Study on Risks to Wind Turbine Arrays from Thunderstorm Downbursts in Different Atmospheric Stability Conditions

open access: yesEnergies, 2021
Thunderstorm downbursts have been reported to cause damage or failure to wind turbine arrays. We extend a large-eddy simulation model used in previous work to generate downburst-related inflow fields with a view toward defining correlated wind fields ...

Frequency Domain Analysis of Alongwind Response and Study of Wind Loads for Transmission Tower Subjected to Downbursts

open access: yesBuildings, 2022
Downburst is one of the high-intensity winds that cause transmission tower failures. The regulations of transmission tower-line systems under downburst wind loads cannot meet the design requirements at present.

Oklahoma Downbursts and Their Asymmetry

open access: yesJournal of Climate and Applied Meteorology, 1987
Abstract Doppler radar data collected each spring in 1979–1984 with the two Doppler radars operated by the National Severe Storms Laboratory (NSSL) are used to investigate the asymmetry of low-altitude divergent outflows of convective storm downbursts in central Oklahoma.

Design Spectra for Evaluating the Dynamic Response of Buildings Under Thunderstorm Downbursts

open access: yesBuildings
This paper presents a spectral method to determine the effect of thunderstorm downbursts on structures. The method integrates the dynamic response of single oscillators subject to input accelerations induced by wind, based on classical earthquake ...

Three‐Dimensional Lightning Characteristics of Severe Convective Weather in Shanghai

open access: yesMeteorological 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

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

open access: yesEarth 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 ...
