    Keywords : wind; turbulence; forest; model; RANS; Lopes; closure; WindSim;

    Abstract : As wind farms continue to take up more land throughout Northern Europe, developers are looking to sparsely populated areas, particularly in northern Fennoscandia, which hosts strong winds but also mixed and patchy forests over complex terrain. The complexity makes wind resource assessments difficult, raising uncertainty and therefore cost. READ MORE
