Zusammenfassung |
The regional ocean operational system remains a key element in downscaling
from large scale (global or basin scale) systems to coastal ones. It enables
the transition between systems in which the resolution and the resolved
physics are quite different. Indeed, coastal applications need a system to
predict local high frequency events (inferior to the day) such as storm
surges, while deep sea applications need a system to predict large scale
lower frequency ocean features. In the framework of the ECOOP project, a
regional system for the Iberia-Biscay-Ireland area has been upgraded from an
existing V0 version to a V2. This paper focuses on the improvements from the
V1 system, for which the physics are close to a large scale basin system, to
the V2 for which the physics are more adapted to shelf and coastal issues.
Strong developments such as higher regional physics resolution in the NEMO
Ocean General Circulation Model for tides, non linear free surface and
adapted vertical mixing schemes among others have been implemented in the V2
version. Thus, regional thermal fronts due to tidal mixing now appear in the
latest version solution and are quite well positioned. Moreover, simulation
of the stratification in shelf areas is also improved in the V2. |
