Title: | Higher resolution physical numerical model of the Mediterranean Sea in the Copernicus Marine Service | Issue Date: | 8-Mar-2016 | Keywords: | Mediterranean Sea Monitoring and Forecasting Centre Copernicus Marine Environment Monitoring Service ocean numerical modeling |
Abstract: | INGV is responsible for the operational production of the physical component of the Mediterranean Sea Monitoring and Forecasting Centre (Med-MFC) of the Copernicus Marine Service Monitoring System (CMEMS). The system was implemented in 2000 by the INGV National Group of Operational oceanography (GNOO) and has been developed in years thanks to a number of European projects. The Med-MFC is a coupled hydrodynamic-wave model with data assimilation component with a resolution of 1/16°. The model solutions are corrected by the variational assimilation (based on a 3DVAR scheme) of Temperature and Salinity vertical profiles (from ARGO, CTD, XBT and Gliders observations) and along track satellite Sea Level Anomaly (SLA) observations. In order to meet the requirements for Copernicus Marine Service Phase I the increase of the horizontal (to 1/24°) and vertical resolution of the hydrodynamic component of Med-MFC has been planned. The major improvements expected from this development are the following: 1) to better resolve the mesoscale processes in the Mediterranean region where the Rossby radius of deformation is about 12-15 km (1/24° is about 4-5 km); 2) to resolve the tidal forcing at Gibraltar, entering from the Atlantic into the Mediterranean, known to provide about 30% amplitude of the tidal signal in the Mediterranean; 3) to better resolve vertical mixing processes. |
