The local wind climate over Sweden and the Baltic Sea area has previously been
investigated by means of a large number of mesoscale meteorological model
simulations using, for instance, 3 typical (geostrophic) wind speeds, 8 typical
(geostrophic) wind directions, and 4 typical months (January, April, July, and October),
in order to represent a large number of different meteorological situations. This gives a
total number of 96 model runs. In each run, the model has been run over 24 hours, in
order to resolve the daily cycle.
The results from these model runs are, then, weighted together, using frequency
distributions for the large-scale (geostrophic) wind directions and wind speeds.
Previously, these distributions have been obtained from long time series of mean-sealevel pressure from a number of meteorological stations.
In order to make the above-described method applicable throughout the world (also over
areas where no measurements are available), 30 years of data from a global
meteorological database are used in order to calculate the above-named frequency
Frequency distributions from both methods are compared, and the impacts on the local
climatological wind field, as predicted by the modelling system, are estimated. This is
done for the area of the Baltic Sea and the surroundings. The results obtained with both
methods are compared against each other, as well as against a number of
