Wind Atlas - wind energy resources on the map of Finland
The Finnish Wind Atlas (2009) is an important tool for estimation of the regional and local wind energy potential in Finland. The wind atlas can be used to assess wind conditions suitable for wind energy throughout Finland or in certain limited areas.
The Wind Atlas web interface contains average monthly and annual values of wind speed (m/s), potential power production (MWh) calculated for three different wind turbines (1 MW, 3 MW and 5 MW) at heights from 50 m to 400 m above sea or ground level.
The Wind Atlas is produced by the European state-of-the-art numerical weather forecasting model AROME (2,5x2,5 km2 grid resolution) and by the Danish Wind Application and Analysis Program WAsP (downscaling to 250x250 m2 grid at selected areas).
The Wind Atlas was produced by simulating the weather of 72 selected months from 1989–2007. The months for simulation were selected based on statistical analyses of the ERA40 and ERA-Interim data sets. The selected months aim to represent average wind conditions over the past 50 years.
The results of the Wind Atlas are based on computer models and represent average wind conditions in a certain area, not in a single geographical point. The results and actual wind conditions always differ to some extent. If the results of the Wind Atlas are used in decision making, the Ministry of Employment and the Economy and the Finnish Meteorological Institute cannot be held responsible for possible economic or other effects that using this data may cause to organizations.
The Wind Atlas was published in 2009.The Wind Atlas project was ordered by the Ministry of Employment and Economy after an international tender had been held. The Wind Atlas was produced by the Finnish Meteorological Institute, with Risoe DTU as a subcontractor. Additional wind data taken at masts and towers were provided for verification of the model results by Vaisala Oyj, WPD Finland and Ålands Vindenergi Andelslag. The project was coordinated by Motiva.
