Review of Wind Field Characteristics of Downbursts and Wind Effects on Structures Under Their Action
BuildingsDownbursts belong to sudden, local, and strong convection weather, which present significant destruction for structures. At any given time, there are approximately 2000 thunderstorms occurring on the Earth.

CLIMATHUNDERR: experimental database of buoyancy-driven downbursts [PDF]
Earth System Science DataThunderstorm downbursts are windstorms due to intense negatively-buoyant flows produced beneath cumulonimbus clouds. Their study has recently attracted significant scientific and media attention due to the current and projected impacts of climate change.

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 ...

On Wind Turbine Loads During Thunderstorm Downbursts in Contrasting Atmospheric Stability Regimes
Energies, 2019 Severe winds produced by thunderstorm downbursts pose a serious risk to the structural integrity of wind turbines. However, guidelines for wind turbine design (such as the International Electrotechnical Commission Standard, IEC 61400-1) do not describe ...

Characteristics of Rainfall in Wind Field of a Downburst and Its Effects on Motion of High-Voltage Transmission Line [PDF]
Shock and Vibration, 2017 Despite most weather-related failures of high-voltage transmission lines (HVTLs) being attributed to the downbursts accompanied by heavy rainfall, research works mainly focused on the behaviors of the high-voltage transmission tower-line structures under
