Exploiting the full potential of Doppler lidars: High‐resolution wind‐gust profiling in significant weather

Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 769, April 2025 Part B.
The evolution of wind gusts is difficult to observe because gusts are short‐lived phenomena that can originate at higher altitudes. During the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL), novel ground‐based remote‐sensing methodologies were applied to measure wind with Doppler lidars in order to provide 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).

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 ...

Wind load impact on tall building facades: damage observations during severe wind events and wind tunnel testing

Frontiers in Built Environment
As global urbanization accelerates, the construction of tall buildings has surged, becoming a defining feature of modern cityscapes. Tall buildings, while contributing to economic growth and urban development, face substantial risks from extreme wind ...

Exploring the Feasibility of Using Commercially Available Vertically Pointing Wind Profiling Lidars to Acquire Thunderstorm Wind Profiles

Frontiers in Built Environment, 2019
While multiple types of remote sensing instruments have been used to investigate wind profiles associated with thunderstorms, the use of profiling Lidars (LIght Detection And Ranging) has been mostly limited to the wind energy sector.
