The offshore wind climate over the Baltic Sea area has been investigated using the three-dimensional higher-order closure MIUU-model from Uppsala University. A technique for modelling the wind climate with this type of model is presented. The results are verified against measurements. Following the good agreement between model estimates and observations, it is judged that the model output may be used to analyse different aspects of the offshore winds in a detail, which is not possible with existing observations. The influence from land/sea temperature differences on the wind climate and the effects of the related thermally driven flows could be investigated. An attempt was made to quantify these effects on the offshore wind power potential over the Baltic Sea.
