Evolution and Structure of a Dry Microburst Line Observed by Multiple Remote Sensors in a Plateau Airport

open access: yesRemote Sensing, 2022
The civilian airplane is a common transportation mode for the local people in the Qinghai-Tibet Plateau (QTP). Due to the profound dynamic and thermal effects, the QTP can trigger strong windstorms during the warm season, during which downbursts can ...

A Retrospective Satellite Analysis of the June 2012 North American Derecho

open access: yesRemote Sensing, 2022
The North American Derecho of 29–30 June 2012 exhibits many classic progressive and serial derecho features. It remains one of the highest-impact derecho-producing convective systems (DCS) over CONUS since 2000.

Numerical Simulation of Long-Span Bridge Response under Downburst: Parameter Optimization Using a Surrogate Model

open access: yesMathematics, 2023
Long-span bridges located in thunderstorm-prone areas can potentially be struck by downburst transient winds. In this study, the downburst time-varying mean wind was simulated by an impinging jet model based on computational fluid dynamics (CFD). To make

Convective environments leading to microburst, macroburst and downburst events across the United States

open access: yesWeather and Climate Extremes, 2022
Downbursts are strong downdrafts of negatively buoyant air associated with convective storms and are capable of producing severe near-surface winds. Microbursts and macrobursts are subcategories of downbursts with the horizontal extent of damaging winds ...

Numerical simulation on load characteristics of transmission tower under downburst and wind-rain conditions

open access: yesZhejiang dianli, 2023
To analyze the response characteristics and failure modes of transmission towers subjected to the combined effects of downbursts and rainstorms, a numerical simulation based on CFD (computational fluid dynamics) is used to investigate the distribution ...

Downburst-Induced Vibration Coefficient of Long-Span Roof Structures

open access: yesBuildings, 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 ...
