[MITgcm-devel] Re: it's probably my faults again, but ...

[Martin Losch]

Hi Patrick,

no,no,no, I am very well aware that I cannot expect "taux" to look  
like the real zonal component on of wind stress (it's the i-component  
on each face, right?), but that's not what I was point at.
I plotted uwind to show you where there are the "holes" in my domain  
(there is one tile missing in North America, one in South America and  
three in Asia, these tiles are all "land" tiles). If you now compare  
the location of the brown (dark red) bars in the taux-plot, they lie  
along the missing tiles (or holes). I have modified the colorbar, but  
the values of taux on these "bars" is 1e14. qnet (and even u/vwind)  
do not have these bars.

Do you agree, that taux points towards a problem? (it may very well  
be connected to my inadequacy of running the MITgcm, but it is a  
problem ...)
