Because of the similar structure of effect on ocean, this analysis concentrates on
a single-point comparison. The chosen points mark the middle of the model area,
the wind farm itself, as well as areas of extreme changes due to the OWF. In sum,
11 positions at different levels, which are surface, 12 m (depth of the thermocline),
30 m (half of model depths), and 60 m (bottom), are included in this analysis. These
positions are pictured in Fig. 5.23 .
A single point analysis is chosen to accent discrepancies over the whole
OWF-affected area. Independent of wind speed velocity wake, dipole in surface
