which we yield with insertion of Eq. (4.23) into Eq. (4.24). The model prediction
reproduces this shape (Fig. 4.19). The sea level attains a depression of >50 cm in the
middle of the model domain after 30 days of simulation. The resultant sea-level gradients trigger surface geostrophic flows of maximum speeds of 40 cm/s running into
the same direction as the wind (Fig. 4.20). Recall that geostrophic flows run along
lines of constant pressure and therefore normal to the model slice. Interestingly, the
