Description:
This study describes a new model implementation for the Mediterranean Sea that has
been achieved in the framework of the Copernicus Marine Environment Monitoring
Service (CMEMS). The numerical ocean prediction system, that operationally produces
analyses and forecasts of the main physical parameters for the entire Mediterranean
Sea and its Atlantic Ocean adjacent areas, has been upgraded by increasing the grid
resolution from 1/16o to 1/24o in the horizontal and from 72 to 141 unevenly spaced
vertical levels, by increasing the number of fresh water river inputs and by updating
the data assimilation scheme. The model has a non-linear explicit free surface and it
is forced by surface pressure, interactive heat, momentum and water fluxes at the airsea
interface. The focus of this work is to present the new modelling system which
will become operational in the near future and the validation assessment including
the comparison with an independent non assimilated dataset (coastal moorings) and
quasi-independent (in situ vertical profiles and satellite) datasets. The results show
that the higher resolution model is capable of representing most of the variability
of the general circulation in the Mediterranean Sea, however some improvements
need to be implemented in order to enhance the model ability in reproducing specific
hydrodynamic features particularly the Sea Level Anomaly.
