Annual mean windspeed gridpoint De Bilt from 1940 - 2080

The black lines in the image below show the annual mean windspeed in gridpoint De bilt at the lowest model level (925 hPa) since 1940 upto the year 2080 in the integration. Each black line represents one of the runs 32 - 62. The red line is the mean of the 31 runs together. The blue line shows the observed annual mean windspeed based on geo wind calculations using dialy mean surface pressure data of three Dutch stations (source Jules Beersma and Geert Jan van Oldenborgh) from 1940-2002.

During the actual simulations the black and the red lines in the image showed the situation at at most 1 hour ago.
