Abstract Plumage is among the most well-studied components of integumentary colouration. However, plumage conceals skin in birds, and as a result presence, evolution function colour remains unexplored. Here we show, using database 2259 species encompassing >99% bird genera, that melanin-rich, black found small but sizeable percentage (~5%) it evolved over 100 times. The spatial distribution follows Gloger’s rule, which states pigmentation endothermic animals increases towards equator....
Abstract. Accurate modeling of wind conditions is vital for the efficient operation and management farms. This study investigates enhancement weather simulations by assimilating local offshore light detection ranging (lidar) and/or supervisory control data acquisition (SCADA) into a numerical prediction model while considering presence neighboring farms through farm parameterization. We focus on improving output during storms impacting Belgian–Dutch cluster located in Southern Bight North...
Abstract. Two-way feedback occurs between offshore wind and waves. However, the influence of waves on profile remains understudied, in particular momentum transfer sea surface atmosphere. Previous studies showed that for swell it is possible to have increasing speeds case aligned wind–wave directions. opposite valid opposed directions, where a decrease velocity observed. Up now, this behavior has not been included most numerical models due lack an appropriate parameterization resulting...
Abstract The importance of wind energy as an alternative source has increased over the latest years with more focus on offshore winds. A good estimation winds is thus major for this industry. Up to now effect wind–wave (mis)alignment not yet been taken into account in coupled atmosphere–wave models study vertical profile and power production estimations farms. In roughness length parametrization Drennan et al . 2003, its extension addressing proposed by Porchetta 2019, are investigated...
Seabirds have evolved numerous adaptations that allow them to thrive under hostile conditions. Many seabirds share similar colour patterns, often with dark wings, suggesting their coloration might be adaptive. Interestingly, these darker wings become hotter when birds fly high solar irradiance, and previous studies on aerofoils provided evidence aerofoil surface heating can affect the ratio between lift drag, i.e. flight efficiency. However, whether this effect benefits remains unknown....
Abstract We present a new planetary boundary layer scheme based on large‐eddy simulations for different atmospheric stability classes. Large‐eddy results are compared with the wind speed measurements from meteorological mast at Test Centre Large Wind Turbines Høvsøre, Denmark. A generic formulation determination of mixing length scale is proposed and incorporated updated closure coefficients derived under realizability constraints by Temel et al. (2018,...
Abstract. Accurate wind and power predictions from numerical models are crucial for farm operation management. This study explores how these can be improved by assimilating local offshore data into a weather prediction model, while simultaneously taking account the presence of neighboring farms. The focus is on Belgian-Dutch cluster located in Southern Bight North Sea. Our results show that, current case with extreme conditions, assimilation upstream reduces mean absolute errors speed,...
Abstract The rapid expansion of wind farms in the North Sea requires a better understanding turbines’ wake effects. In this study, classification patterns under different atmospheric boundary layer stability conditions is investigated. For purpose, Weather Research and Forecast model utilized to calculate farm effects over southern for year-long period. characterized by value Monin-Obukhov length, seven classes are considered. results have shown that predominance condition depends on...
Abstract Rain-driven wind turbine blade erosion, particularly in offshore locations, has been observed as early within 5 to 7 years of operation, which is below the lifetime expectancy design age 20 25 year. Due harsh atmospheric conditions offshore, preservation integrity become a fundamental necessity. To address this challenge, we compare precipitation maps from two distinct sources (satellite data and reanalysis product) over 12 region North Sea, pursue insights into local weather...
Abstract Modern research endeavors in wind energy have been increasingly focused on achieving accurate representations of turbine loading across diverse atmospheric conditions. Recent advancements numerical weather prediction techniques make it possible to downscale conditions for operational use, underscoring the importance including air-sea interactions using models such as Coupled-Ocean-Atmosphere-Wave-Sediment Transport model improve predictions. Nevertheless, challenges high...
Abstract. With the rapid increase in wind farm developments, it is essential to evaluate impacts of newly constructed farms on adjacent existing and planned farms. Various numerical models have been used study interactions between farms, spanning from fast-running engineering weather prediction models. These are anticipate mitigate wake effects future energy deployments. Since atmospheric conditions variable over year, important characterize variation for operation planning. Due higher...
