Modelling in the Mediterranean

Regional summary

The Mediterranean Sea is a semi-enclosed sea, characterised by an inverse estuarine circulation with the Atlantic Ocean. Morphologically, it can be divided in two sub-regions (the Strait of Sicily separates the western and eastern Mediterranean), and it is characterized by the presence of a narrow continental shelf and two marginal sub-regions (the Adriatic Sea and the Aegean Sea). The major inflow into the Mediterranean is nutrient-poor, oxygenated Atlantic surface water through the Strait of Gibraltar. The western sub-basin is seasonally stratified and large parts of the open ocean eastern sub-basin are permanently stratified.

Two model systems were developed in the Meditteranean by different research institutes.

1. Istituto Nazionale di Oceanografia e di Geofisica Sperimentale (Italy) model covers the whole of the Mediterranean using the following system:

Simulation period: 1999-2013
Models used: OPATM-BFM-ECOPATH with ECOSIM<
Assimilation method:  3D-VAR
Forcing:  MyOcean Mediterranean Forecast System (MFC) run by INGV (IT)
