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.
