Fig. 6.8 Change in surface elevation due to OWFs in case of different wind direction cases
(gwind direction (a)-(h) from N to NW) after 1 day of simulation. The wind direction is defined at
height of geostrophic wind. Units given in m.

specifically exemplifies in the case of wind direction SW that the
vertical motion affects the whole model depths with maximal changes between
10 m and 15 m. The intensity of the OWF induced vertical velocity
w
is stronger
over the whole depth towards the coasts, especially for downwelling. The analysis
of the OWF effect on the ocean system in Sect.
5.3.6
shows that intensification is
supported by shallower water.
Changes of the velocity components u and v
at surface due to OWFs are
illustrated in Figs.
