[MITgcm-devel] free drift ice model

[Matthew Mazloff]

Hi Dimitris and Martin and others,

I want to use a free drift sea ice model for my Southern Ocean state  
estimate.  I intend to set

Uice = A x Usurface  +  B x Uwind

So I need to determine A & B.  I am under the impression that over  
most of the Southern Ocean the ice is loose and A will be about 1.
(I believe in the current model set up the wind stress acts on the  
ocean as if the ice wasn't there.  If this is so setting A = 1 would  
make for a more consistent depiction of things...right?)

A suggestion by JMC was to run the model with the full sea ice  
dynamics and then find A and B by linear regression.

I was wondering what people think of this idea and if anyone has an  
idea as to how to determine A and B.  Are there already numbers out  
there for free drift models?

Thanks,
Matt
