The current fields, for the period over which the drifting buoy provided data, were estimated for the Bay of Biscay.
This output information was used in the LPTM, to calculate the dispersion of a particle which simulates the movement of the drifting buoy.
The sea surface current and temperature predictions derived by ROMS model for April 13th 2003 are shown in Figs. 4
and 5.
Although current field structure is influenced highly by the wind characteristics on that particular day, some typical features of the general water circulation, for the Bay of Biscay system, can be observed.
On this day, the Atlantic southwesterly component of the wind stress forces the stable poleward current, established during previous days, towards the northeast along the continental slopes of Galicia and the Cantabrian Sea, and towards the north-northwest along the French coast (Fig. 4).
Wind stress maxima and changes in coastline orientation and topography, force the flow offshore at some locations along the Cantabrian Sea; this generates, finally, cyclonic eddies (with average velocities around 20–30 cm/s).
These structures transport both warmer waters and coastal waste products, inducing coastal upwelling; these warmer waters, which come from the southwest, are advected towards the Bay of Biscay by the poleward current established (Fig. 5).
