Cumulative hydrodynamic impacts of offshore wind farms on North Sea currents and surface temperatures
Author: Christiansen, Nils; Daewel, Ute; and Schrum, Corinna
Abstract. Offshore wind farms are increasingly shaping coastal ocean dynamics, yet their cumulative physical impacts remain poorly quantified. Using decade-long, high-resolution simulations of the North Sea, we show that large-scale offshore wind development can reduce current velocities by up to 20% and reshape local tidal energy distributions. Wind and tidal wakes exert distinct but interacting influences on ocean physics: wind speed anomalies drive far-field hydrodynamic impacts, while structure-induced drag intensifies local turbulence and mixing. Turbine spacing emerges as a key . . .

Author: Akhtar, Naveed; Geyer, Beate; and Schrum, Corinna
Abstract: The European Union has set the ambitious goal of becoming climate neutral by 2050, which has stimulated renewable energy production and accelerated the deployment of offshore wind energy in the North Sea. Here, a high-resolution regional climate model was used to investigate the impact on the sea surface climate of large-scale offshore wind farms that are proposed for the North Sea. The results show a significant reduction in the air-sea heat fluxes and a local, annual mean net cooling . . .

Author: Koppen, Erik; Ekelschot-Smink, Madelon; and Boon, Jaap
Noise from wind turbines is often a significant concern for nearby residents. To better understand the actual impact of wind turbine noise, an interactive app was utilized across several wind projects, allowing residents to easily report their real-time experiences with turbine noise. One such project involves 26 wind turbines in the Netherlands, grouped into three geographically separated clusters, spread over a 26-kilometre stretch along a busy motorway. For two years, starting from the turbines’ initial operation, residents could report noise-related . . .

Author: Pockelé, Josephine Siebert; and Merino-Martinez, Roberto
The human perception of two wind turbines of different sizes, a small NTK turbine and a larger NREL model, was evaluated through their synthetically auralised sound. A wide range of wind speed conditions and observer locations was considered. The simulated sounds were analyzed using equivalent sound pressure levels and psychoacoustic sound quality metrics. Moreover, listening experiments were conducted to evaluate the human response to the same sounds. The least-squares models fitted to the results provided scaling laws for the different . . .
