The CORDEX.be initiative as a foundation for climate services in Belgium [PDF]

, 2018
The CORDEX.be project created the foundations for Belgian climate services by producing high-resolution Belgian climate information that (a) incorporates the expertise of the different Belgian climate modeling groups and that (b) is consistent with the ...

Damaging thunderstorms in Finland in June 2021

Weather, Volume 80, Issue 4, Page 111-119, April 2025.
Thunderstorms are common in Finland, however, high‐impact damaging cases do not occur every summer. On 21–23 June 2021, three damaging thunderstorms, named Ahti, Paula and Aatu, occurred in Finland. We provide an overview of the thunderstorms and their environment and impacts.

Unsteady Aerodynamics of Bridge Decks in Transient Winds: Vortex Memory Effects and Path‐Dependent Responses

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
This study unveils novel vortex memory mechanisms governing unsteady aerodynamics of streamlined bridge decks under transient winds via CFD simulation with the SST k‐ω model (the acceleration magnitudes were set as ±5 m/s2 and ±10 m/s2, respectively).

Characteristic Analysis of the Downburst in Greely, Colorado on 30 July 2017 Using WPEA Method and X-Band Radar Observations

Atmosphere, 2018
As a manifestation of low-altitude wind shear, a downburst is a localized, strong downdraft that can lead to disastrous wind on the ground surface.

Research on flow field characteristics of moving downburstsand dynamic response of wind turbines

Kongqi donglixue xuebao
The moving downburst, influenced by the atmospheric boundary layer wind, results in a constantly shifting jet center, causing significant changes in the wind field structure and radial velocity characteristics compared to stationary downbursts.

Optimal recovery from microburst wind shear [PDF]

Severe low-altitude wind variability represents an infrequent but significant hazard to aircraft taking off or landing. During the period from 1964 to 1985, microburst wind shear was a contributing factor in at least 26 civil aviation accidents involving

Experimental Modelling of Downburst and Downburst line Outflows

, 2020
The outflow velocity vector fields of simulated stationary thunderstorm downbursts and downburst lines were resolved in two plane orientations, vertical and horizontal, using a dense fluid release system and Particle Image Velocimetry. Single event releases were scaled to show agreement with past studies based on radial velocity magnitude and location ...
