[MITgcm-support] do ocetaux and ocetauy reflect cell-averaged stress in a sea-ice model?

many thanks martin.

Hi Dan,

the diagnostics oceTaux/y are exactly what you need.
IF you need convincing: you’ll most likely see the (damping) effect of sea ice in these fields, too.

Hello All!

I would like to apply surface stress to an ocean model without the sea ice package implemented, but using the effective surface stress — i.e. that imposed by sea ice, and imposed by winds where there is no sea ice — from a similar run using the sea ice package.

Would the diagnostics OceTAUX and OceTAUY be appropriate for this? They save the arrays fu() and fv(), which i know are updated by the sea ice model, but im not sure if they are saved at the correct point in a time step.

Many thanks if anyone can advise!
Dan
