Semiempirical Models of Speedup Effect for Downburst Wind Field over 3-D Hills

open access: yesAtmosphere, 2023
Downbursts occur frequently in mountainous regions, such as the southwest of China, and causing extensive damage to engineering structures. While some researchers have developed semiempirical models for the speedup effect, most are based on the wind ...

Thunderstorm Downbursts and Wind Loading of Structures: Progress and Prospect

open access: yesFrontiers in Built Environment, 2020
In 1961, Davenport published a paper, considered by most to be a critical work in the study of wind engineering, in which meteorology, micrometeorology, climatology, aerodynamics, and structural dynamics were embedded in a homogeneous framework of the ...

Characteristics of Rainfall in Wind Field of a Downburst and Its Effects on Motion of High-Voltage Transmission Line

open access: yesShock 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

CLIMATHUNDERR: experimental database of buoyancy-driven downbursts [PDF]

open access: yesEarth System Science Data
Thunderstorm 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.

Experimental Simulation of Thunderstorm Profiles in an Atmospheric Boundary Layer Wind Tunnel

open access: yesApplied Sciences, 2023
Thunderstorms have different features in comparison with synoptic events, including a typical nose-shaped mean wind speed profile and non-stationary characteristics in time intervals from 10 min to 1 h. The simulation of thunderstorms in traditional wind

On Wind Turbine Loads During Thunderstorm Downbursts in Contrasting Atmospheric Stability Regimes

open access: yesEnergies, 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 ...
