Ten-day variability of the summer circulation in the North Adriatic

Current, temperature and salinity data, have been analysed together with related meteorological and hydrologic data. After dividing the current series into three nearly equal subintervals, residual currents have been calculated for each of them. The major feature this exercise revealed was a variability at a time scale of about ten days. Temperature data collected in the area have pointed to stratification as the factor controlling the observed current variations. The stratification itself was influenced by buoyancy fluxes and wind forcing. However, further theoretical and empirical work is needed to establish conclusive evidence and elaborate dynamics of the observed phenomenon.
