[MITgcm-support] Arctic configuration

[Jinlun Zhang]

Samar,

After we coupled the sea ice model into MITgcm, I did a rough arctic
configuration with about 40 km resolution. I got pretty decent sea ice, in a
nice agreement with obs. pattern. The ocean circulation is pretty good too, with
a nice Beaufort Grye. But I have not analyzed the results in detail. For a
regional model, the key is open boundary conditions. I have not put a handling
of ice open boundary into MITgcm yet (planning to do it at some point), however,
a good ocean o.b.c would alleviate the problem of lacking ice o.b.c. You might
also want to do a domain rotation to let model equator goes thru, preferably,
the north pole. But make sure using actual latitude to calculate the Coriolis
force.
