Assessing Downburst Kinematics Using Video Footage Analysis
Measurements of downburst outflows using standard meteorological instruments (e.g., anemometers) are rare due to their transient and localized nature. However, video recordings of such events are becoming more frequent.

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

Analytical model of high-voltage transmission line subjected to the downburst wind with rainfall
There have been many reports recently on unanticipated galloping and collapse accidents of tower-line systems due to downburst wind with rainfall. Although wet downburst is characterized by high-velocity wind with rainfall, very little research work is ...

The Predictability of the Southern England 23 October 2022 Severe Downbursts
Accurate 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 ...

Mechanisms of Projected Changes in Thunderstorm Downburst Environments Across the United States
Responses of downdraft convective available potential energy (DCAPE) to global warming were investigated using the Community Earth System Model (CESM2) under a high‐emission scenario through the year 2100.

Investigating the impact of atmospheric stability on thunderstorm outflow winds and turbulence [PDF]
Downburst events initialized at various hours during the evening transition (ET) period are simulated to determine the effects of ambient stability on the outflow of downburst winds.
