5.8 Exercise 24: The Abyssal Circulation
151
Fig. 5.20 Exercise 24. Distributions of tracer concentration (shading and contours) and horizontal
flow field (arrows) in the uppermost 200 m of the water column after 120 days of simulation.
Arrows for speeds <1 cm/s are omitted. Velocities are averaged over 2 × 2 grid cells
Fig. 5.21 Exercise 24. Locations of Lagrangian floats, initially located in the formation region of
dense water north of y = 800 km after 120 days of simulation
the ocean interior, presumably because of the relatively short simulation time. Note
that the artificial southern coastline supports an eastward zonal flow. In reality, the
Deep Western Boundary Current encounters the equator. Dynamical consequences
of this encounter are discussed in the next section.
