Figure 9 displays anomalies of the upper-layer
thickness (right panels) and streamfunction
(left panels) every 60 days. The figure shows
the anomaly fields only for the western part
(0 < x < 3200 km) of the model domain in order
to emphasize the process around the ridge.
It is interesting to note that the negative
(positive) anomaly of the streamfunction
is released from the ridge to the west when
the negative (positive) anomaly of the upper-layer
thickness reaches the western edge of the
ridge from the east.
