EUROMODEL-II-MTP

Euromodel was carried on global basin, regional and process studies in both modelling and in situ experiments, with particular emphasis on the sseasonal and mesoscale  variabilities. Synergy between observations (in situ and  satellite), theoretical, physical and numerical models were systematically used.

The basin scale circulation was simulated using LODYC and GHER ocean general circulation models. The surface forcing was obtained from a meteorological-assimilated data set (PERIDOT output). In conjunction with the PRIMO experiment, in situ basin scale experiments monitored the transports through the straits to provide the models with realistic lateral boundary conditions. The seasonal variability of the basin scale circulation as well as heat and salt budgets were extensively investigated.

The mesoscale variability could strongly influence, and even dominate the general circulation in regional basins. In situ, numerical and laboratory experiments were conducted in a number of regions (the Balearic and Alboran seas, the Algerian Basin and the Sardinia Channel) to apprehend the physical mechanisms involved in the mesoscale circulation. In situ observations were complemented with remote sensing data (altimeter, AVHRR, scatterometer, SAR, CZCS). The path and the instabilities of intermediate waters in the Western Mediterranean and the Eastern Atlantic Ocean in front of the Strait of Gibraltar, as well as upper ocean mesoscale variability and its implication to downward energy propagation were investigated.

Advanced research in model-based data assimilation was initiated to synthesize the different sources of information, providing a coherent representation of the circulation.

As a preliminary phase to the development of models suitable for environmental purposes, a bio-hydrodynamic model was set up through primary productivity studies.
