Fig. 3.3.15: Relative Frequency distribution of wind speed [%] of the ENSEMBLES RCMs and ERA-40 in the four North Sea boxes for the period of 1971- 
2000. X-axis does not show whole range of possible wind speeds, to enhance details for smaller wind speeds. Maximum wind speed of all models, days and grid 
points in the four areas is 29.12 m/s
