A test of the KPP mixing algorithm
was performed by determining if an
Ekman spiral was produced by
quasi-steady surface momentum flux
forcing. A special run was performed
with 30 vertical layers. Proceeding
downward, the minimum layer
thickness was 3, 4, 5, 6, 7, … m.
During winter at a model grid point
within the North Atlantic Trade
Winds (near 15N), a reasonable
Ekman spiral was present in the
upper 50 m.
