[RegCNET] Minimum horizontal resolution

[Tompkins Adrian]

hi Béatrice,

I am not a regular REGCMer (yet), but can answer this one.  The model is 
hydrostatic and therefore resolutions of 1km are not possible.  Usually 
the limit for a hydrostatic model is about 7 to 8 km.  I understand some 
people have used REGCM with 10km in the past.  Plans are afoot to create 
a non-hydrostatic version of REGCM but this will take a while.

best,

Adrian
