Computational simulation of thunderstorm downbursts and associated wind turbine loads [PDF]
textWind turbines operate in a constantly changing wind environment. This requires modeling and simulation of extreme events in which the wind turbine operates and a study of associated turbine loads as part of the design practice and/or site assessment.

Thunderstorm Downbursts and Wind Loading of Structures: Progress and Prospect
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 ...

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

Using crop fall patterns to provide an insight into thunderstorm downbursts [PDF]
This paper examines whether crop fall patterns due to thunderstorm downburst-like events can provide an insight into the flow structure of a downburst. To explore this phenomenon, a novel three-dimensional analytical model for the velocity flow field is ...

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

Análise da ocorrência de Downbursts no Brasil e estudo da simulação do fenômeno [PDF]
Calamidades naturais são cada dia mais frequentes e a maior parte delas está relacionada aos danos ocasionados por tempestades severas. Desta forma, são necessários estudos que auxiliam tanto na compreensão desses fenômenos quanto na previsão dos mesmos ...

Abstract Windthrow is a significant disturbance in many forests globally during which strong winds damage trees or other large flora, yet its role in arid ecosystems remains largely understudied. The saguaro cactus (Carnegiea gigantea), a keystone species of the Sonoran Desert, is a long‐lived, massive succulent whose demography is primarily thought to

Abstract Accurate short‐term forecasting of thunderstorm gusts remains a major challenge in the Beijing–Tianjin–Hebei region due to limited temporal resolution, the lack of vertical velocity and thermodynamic data, and the difficulty of coupling multi‐scale features.
