<strong>Wind</strong> Speed [m/s]<br />
Figure 2.15 Average wind speed profile all sectors. D<strong>at</strong>a from May 1999 to November<br />
2002.<br />
<strong>Wind</strong> speed profiles offshore are expected to conform to logarithmic profiles, but when<br />
looking <strong>at</strong> the observed average wind speeds <strong>at</strong> the four levels in Figure 2.16, the<br />
figures reveal th<strong>at</strong> the wind speeds <strong>at</strong> 62 m are somewh<strong>at</strong> higher than could be expected<br />
from a logarithmic prediction.<br />
