Models, Data, and Methodology - On the Effect of Offshore Wind Farms on the Atmosphere and Ocean Dynamics - page 26

The results of meteorological forcing are presented in Chap. 4 ; the results of
these runs for the ocean are represented in Chap. 5 , as well as the source code
manipulations of HAMSOM.

3.3.2 North Sea Simulations: TOS-02

The second type of simulation, TOS-02, is used for realistic runs of the North Sea
and especially over the German Bight. Simulations of the North Sea are separated
into two case studies aiming to estimate possible OWF impacts on the German
Bight under more realistic conditions.
Case study I analyzes the OWF effect on the German Bight under a theoretical
assumption of constant wind directions during a 1-day simulation.
Case study II is an adoption of a real passed meteorological situation of 16-
19 June 2010.
The analyses of the OWF s impact on the German Bight consider a strong

offshore wind farm demanded within the German EEZ. The OWF expansion for
the German Bight that was used here is called

'

B1-2030much, which consists of

' '

8,590 wind turbines and is explained in details in Chap. 6 .

Model Area in TOS-02
Figure 3.6 clarifies three model areas for simulations of the North Sea. The green
encircled area comprehends the North European Shelf (HAMSOM NES); the red

Fig. 3.6 Left : Overview of model areas in TOS-02. The green area marks the application to the
European shelf (HAMSOM NES) of WOA-01 data used at boundaries. This model provides
boundary data for the North Sea model (HAMSOM NS), shown by the red area . The orange area
shows the model area of the atmosphere model METRAS, which fully includes the exclusive
economic zone ( light blue line ) of Germany. Right : Bathymetry of HAMSOM model area NS in
