In
 this and the seven subsequent
 slides,
 five annual cycles of upper
 ocean
 variability are illustrated by
 imaging
 the temperature field
 and
 superimposing the vertical
 coordinate
 interfaces and the
 mixed
 layer base (thick line).
 
 At
 the TRDW grid point, results
 are
 generally similar in the
 North
 Atlantic Trade Wind belt
 at
 the southern edge of the 
 subtropical
 gyre. The KPP mixed
 layer
 tends to be thinner than in
 the
 two K-T mixing cases. Long-
 term
 climate drift is not observed.
