Welcome to our windatlas section

 

At present, the wind atlas methodology – in the form of the WAsP program – has been employed in about 110 countries and territories around the world. In the map below these countries are shown in blue and red. National wind atlases exist for more than 30 countries (marked in red); many of these atlases contain wind data and wind statistics on disk. A list of the 'red' wind atlas countries with references is given here. A list of other wind investigations and data bases is given here.
     
                    

 

These pages are dedicated to the world of wind atlases, the wind atlas methodology and wind atlases of the world. The pages are established and maintained by members of the WAsP team at DTU Wind Energy, Risø Campus in Roskilde, Denmark.

Some wind atlases are available from DTU Wind Energy: the European Wind Atlas, the Russian Wind Atlas and the Wind Atlas for the Gulf of Suez 1991-95.

All other wind atlases must be obtained directly from the publishing institution. A list of major national and regional wind atlas studies is given here.

Other comprehensive wind investigations and databases are listed here.


What is a wind atlas?

Most people think of an 'atlas' as a book or bound collection of maps, sometimes with supplementary illustrations and graphic analyses. However, this is not exactly the way we think of an atlas here.

We use a more general meaning of the word atlas: "An atlas is a volume of tables, charts, or plates that systematically illustrates a particular subject" − where the subject in a 'wind atlas' is the wind climate of a particular region or country. Another definition often used is: "A wind atlas is a systematic and comprehensive collection of regional wind climates (RWC) derived by the wind atlas methodology".

So, an 'atlas containing wind maps' and a 'wind atlas' are two different things − even though the wind atlas could contain some maps...

The wind atlas methodology

The wind atlas methodology in general was first developed and described in detail for the European Wind Atlas.

Wind atlas methodologies makes it possible to transfer detailed information about the mean wind climate from one location (the predictor site) to another (the predicted site). The predictor site can be a meteorological station / wind-monitoring mast, or it can be a grid point in a mesoscale modelling domain. In the latter case, one may think of the model grid point as a virtual meteorological station. The predicted site often corresponds to the location and height of a specific wind turbine generator.

Observational wind atlas methodology (predictor is a real-world met. station)

Numerical wind atlas methodology (predictor is a virtual met. station)
