One
 annual cycle of upper ocean
 variability
 is illustrated by
 imaging
 the temperature field
 and
 superimposing the vertical
 coordinate
 interfaces and the
 mixed
 layer base (thick line).
 
 The
 annual cycle at point EQTR
 represents
 variability at the
 Equator.
 Results are generally
 similar,
 but summer upper ocean
 cooling
 due to enhanced
 equatorial
 upwelling is stronger
 in
 the MICOM mode case.
