[MITgcm-support] UV_VEL_Z

[Angela Zalucha]

Hi,

I am interested in the diagnostic UV_VEL_Z (#40, Meridional Transport of 
Zonal Momentum), which I understand is the time average of u*v.

But I am confused because available_diagnostics.log (see below) says its 
"mate" is itself.  What does that mean?  Is there another quantity I 
should be outputting with it (like uvel and vvel must be output together)? 
How do I convert this in matlab to a lat lon grid?  Like this?

uvcube2latlon(x,y,uv_vel_z,uv_vel_z,xi,yi)

or this?

cube2latlon(x,y,uv_vel_z,xi,yi)

or...?

Thanks,
    Angela
