This paper presents an analysis of stratification dependent mean velocity profiles measured in a Norwegian coastal wind climate, and its comparison with models available in the literature. For this purpose we use 3 years of observations from a 100 m meteorological mast located at the Fr⊘ya island (150 km west of Trondheim, Norway), equipped with a set of 2D ultrasonic anemometers. The presented analysis is preceded by a general description of the site wind climate, the atmospheric stratification, the surface roughness, and the surface layer height. Finally, the measured wind velocity profile is compared with selected models: the basic power and logarithmic law and the stability-corrected models: stability-corrected logarithmic wind profile, the Panofsky&Dutton model, the Peña boundary layer height corrected model and the correlation based Smedman and Högström model.
