Fig. 5.35 Comparison of OWF effect on velocity components (a) u and (b) w ,(c) temperature,
and (d) salinity based on forcing F01 ( blue ) and F03 ( red ) over depth at two, respectively for u -
component three, positions. P 1(0, 12) ( solid lines ) is placed 12 km southerly of OWF and P 2(0,6)

( dashed lines ), 6 km northerly. P 3(0,0) ( dashed-dotted lines ) for u -component is positioned within
the OWF. Horizontal dotted line marks depth of the thermocline; vertical one separates positive
and negative values

The cooling of the upper layers dominates the differences in hydrographics of
F01 and F03 at 12-m depth. Here, the temperature is correlated by 0.83, salinity
only by 0.25 due to discrepancies within the OWF and at P + 1 in Fig. 5.36g .
Accordingly, high are the RMSD of 0.45 C and 0.017 psu along the positions of
investigation. Below 12 m, the full forcing has only a weak impact on ocean
systems.
Figure 5.37 documents that ocean variables at 16 m over investigated positions
are highly correlated by 0.93-1.00. While w -component and temperature have the
best correlations, salinity gives the worst one. But from 18-m depth down to
bottom, the OWF effect of run F03 on salinity adjusts to the OWF effect of run F01.
