Downburst-Induced Vibration Coefficient of Long-Span Roof Structures
Buildings, 2022 Long-span roof structures are vulnerable to being damaged by downbursts due to the sensitivity of such structures to wind loads. However, there is still no simple and practical method for the downburst-resistant design of such structures to date ...

Fragility Analysis of Transmission Towers Subjected to Downburst Winds
Applied Sciences (Switzerland), 2023 A downburst is a typical local highly intensive wind all over the world, which is attributed to be the main cause of wind damage to transmission lines in inland areas worldwide.

The Predictability of the Southern England 23 October 2022 Severe Downbursts
Atmospheric Science LettersAccurate prediction of damaging straight‐line wind events from convective storms relies heavily on storm morphology and nowcasting. Utilising the Microburst Wind Potential Index in ensemble forecasts we examine the predictability of its different ...

Automated Recognition of Macro Downburst Using Doppler Weather Radar
Atmosphere, 2022 In light of the macro downburst’s ground divergent flow field characteristics and high reflectivity, this paper proposes an algorithm for identifying the downburst area using a Doppler weather radar low-level radial velocity and reflectivity factor ...
