[MITgcm-support] CheapAML problems with non-zero wind

[Deremble, Bruno]

Hi Patrick,

I wonder if this is related to a CFL criteria. 
try to increase cheapaml_ntim (in &CHEAPAML_CONST) in data.cheapaml (the number of atmospheric time steps per ocean time step).
I also recommend  to use an advanced advection scheme (option useFluxLimit=.TRUE., in section &CHEAPAML_PARM02 )
last, you can try to adjust the diffusion coefficient cheapaml_kdiff (&CHEAPAML_CONST) (set by deffault to 1e4). Given your super high resolution, I would lower it.

hope this helps
