HYCOM
run in MICOM mode produced results extremely close to MICOM
|
|
|
2.8,
indicating that code changes in HYCOM did not degrade the quality of the
|
|
solution.
|
|
|
| • |
Many
observed shortcomings of these HYCOM simulations can be traced to
|
|
|
the
lack of an ice model, surface forcing errors, the simple initial
conditions,
|
|
|
and
the lack of river runoff.
|
|
|
| • |
The
choice of which two thermodynamical variables are advected and also
|
|
|
|
mixed
in the vertical coordinate adjustment algorithm did not have a
|
|
|
noticeable
influence on the solutions even though in the KPP (theta-S)
|
|
|
experiment,
temperature was not conserved.
