| Zusammenfassung |
| We describe the theoretical basis, implementation, and validation of
a new parametrisation that accounts for the effect of large offshore
wind farms on the atmosphere and can be used in mesoscale and
large-scale atmospheric models. This new parametrisation, referred
to as the Explicit Wake Parametrisation (EWP), uses classical wake
theory to describe the unresolved wake expansion. The EWP scheme is
validated for a neutral atmospheric boundary layer against
filtered in situ measurements from two meteorological masts situated
a few kilometres away from the Danish offshore wind farm Horns Rev I.
The simulated velocity deficit in
the wake of the wind farm compares well to that observed in the
measurements, and the velocity profile is qualitatively similar to
that simulated with large eddy simulation models and from wind
tunnel studies. At the same time, the validation process highlights
the challenges in verifying such models with real observations. |
