Proven to have very high quality!
Used as boundary conditions for regional and local scale
StormGeo models.
Local scale numerical modelling is strongly dependent
on Initial Values!

Numerical weather prediction models
Observations are crucial!

Virtual Wind Measurements –

Large variance within a wind park
ERA INTERIM – for location climatology
New areas handled by StormGEO
Height corrections – Complex terrain
•
Due to small scale terrain effects
not catched by the 1 km model.
•
Input:
– Height of the model surface
– Surrounding ’real’ terrain
– The exact altitude at the
specified location
•
This gives much more accurate
wind speed estimates.
•
The correction depends on model
setup and type of terrain.
•
Still - watch out for non linear
phenomenas like recirculation and
near extremely steep edges in the
terrain…
