This large scale pattern is the oceanic counterpart of the climatological (over the 4 simulated years) atmospheric pressure field used to force the model. 29 Introducing the Atmospheric pressure forcing, a large scale zonal gradient is observed in both the cases (filtered and time splitting algorithms).

In both the cases (filtered or time-splitting) the introduction of the AP forcing increases the standard deviation (variability) of the SSH during the simulated period (differences are, in general, negative). As a consequence of the additional forcing introduced, the basin has a large scale oscillation increasing the SSH variability. However, the larger variability (temporal/spatial) is smoothed (“filtered”) in the filtered free-surface case as evident from the smaller values in the upper panel of the figure below. This different behavior is particularly evident in the shallow areas. [[BR]] 32 34 [[Image(fig.03.png)]] 35 [[BR]] 33 36 34 37
