This scenario simulates the surface and a Mediterranean Outflow Water (MOW) escaping to the Atlantic near the sea bottom. The MOW has two different main paths: northwards, along the Iberian slope, reaching as far as the Scandinavian Peninsula, thereby influencing the formation of North Atlantic Deep Water (NADW), and southwestwards propagating into the Atlantic Ocean. In this simplified scenario we want to study the way a gravity current, like the MOW, behaves for different outflow conditions. The emphasis is on understanding how distinct outflow conditions lead to different propagating depths and mixing that may affect NADW formation under predicted global change future scenarios. The ROMS model domain is centered in the area of the Gulf of Cadis. The northern and southern boundaries are delimitated by the Iberian Peninsula and the Moroccan coast, while the eastern boundary is at 6ºW, near the Camarinal Sill, and the western boundary is open, reaching as far as Cape San Vicente. The imposed boundary conditions consist in two layers of different density, the upper one simulating the AW and the lower simulating the MOW. The grid has 96 X 64 grid points with a resolution of about 3 km and 36 sigma levels. The complex topography of the area is simplified through a slope with two different zonal dependences: the initial (1/3 of the domain) decay of the bathymetry at the east is adjusted by a hyperbolic tangent function, followed by a constant slope.
