Abstract
(English)
The effects of wind stress on the variability of the surface circulation in the Ligurian Sea are investigated by the analysis of a long time series of marine currents and meteorological observations and by numerical model simulations. Observed currents in the upper 50 m are mainly directed NW, according to the general circulation of the area and display the same pattern slightly attenuating the intensity with the depth. Most of the sub-daily variability is due to the inertial currents, which occur at all the examined depths very often. The direction and the intensity of the current in the near surface layer (0-8 m) is sometimes different from those recorded in the layers below. Observations and model results indicate that the wind is able to modify significantly the currents in the upper 14-15 m, thus explaining a huge part of the observed variability.
