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.

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

Automated Recognition of Macro Downburst Using Doppler Weather Radar
In light of the macro downburst’s ground divergent flow field characteristics and high reflectivity, this paper proposes an algorithm for identifying the downburst area using a Doppler weather radar low-level radial velocity and reflectivity factor ...
