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.

Downbursts are strong downdrafts of negatively buoyant air associated with convective storms and are capable of producing severe near-surface winds. Microbursts and macrobursts are subcategories of downbursts with the horizontal extent of damaging winds ...

Dual Polarization Radar Characteristics of Severe Downburst Occurred in Weak Vertical Wind Shear
Based on S-band Dual polarization doppler radar data and conventional observations, characteristics of 3 severe downbursts occurred under the background of weak vertical wind shear are analyzed, and their possible physical formation mechanisms are ...

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 ...

Predicting small-scale, short-lived downbursts : case study with the NWP limited-area ALARO model for the Pukkelpop thunderstorm [PDF]
The authors consider a thunderstorm event in 2011 during a music festival in Belgium that produced a short-lived downburst of a diameter of less than 100 m.

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.

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 ...
