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 ...

Mechanisms of Projected Changes in Thunderstorm Downburst Environments Across the United States
Geophysical Research LettersResponses 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.

Downburst-Induced Vibration Coefficient of Long-Span Roof Structures
Buildings, 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 ...

Wind Engineers, JAWE, 1985 Downbursts can be a significant hazard to aviation safety as well as to agricultural activities, structures and buildings on the ground. Major damages on the surface, airline incidents in the past, worns on the mechanism of the downburst occurrence and recent efforts to detect eho downburst are reviewed.
