[MITgcm-support] advection scheme for T/S

[Jean-Michel Campin]

Hi Samar,

The results could be significantly different between Centered, 2nd order
with AB2, and DST3. 
For a passive tracer, the differences will be larger at high CFL
number, more diffuve with DST3 and more dispersive with 2nd.O.
Now, when you allow feedbacks to the dynamics (an active tracer
like temperature), you can get different results even at small CFL,
but in this case, it might be mainly due to vertical advection.

This is all I can say at this point.

See you,

Jean-Michel
