[MITgcm-support] north-south or south-north gridding?

Hi Martin,

Thanks for clarifying the convention - why do all you modellers think upside down?  What is that?!

Like i said (  (o;  )  the grid i define is read in by mitgcm as i intended - the co-ordinates that are listed in the run_output.txt go from -50 to -80, the area i see in grid.nc covers the geographic region i intended.  Of course i can rewrite all my input files to run south to north, but i'm interested to know :-  will there be any repercussions in, for example, the direction the currents are calculated or anything bizarre that i might not be able to detect, or is MITgcm clever enough to calculate everything the correct way round regardless of whether j=0 is north or south of j=end  (given that it's got the right lat/lon so that the coriolis force is OK) ?

Cheers.  It's almost summer in new zealand (:
jill.
