[MITgcm-support] Viscosity

[Ada Gjermundsen]

Hi,

I'm running MITgcm in an ocean only configuration using only the GM
package. The horizontal grid resolution is 1 x 1cos(lat). For the viscosity
parameters I have used viscAr=1.E-4, viscAhGrid=0.1,. This gives a
horizontal viscosity which depends on the time step. I would prefer to have
a viscosity which does not depend on the time step. Do some of you have
some recommendations for what kind of viscosity scheme preferable for a 1
deg resolution on a Lon-Lat grid?

Cheers,
Ada Gjermundsen
