[MITgcm-support] C grid and pressure

[Nicolas Grisouard]

> Normally we don't care about the "static" or "background" part of the hydrostatic forces on the topography. The pressure due to the fluid at rest doesn't have a dynamical effect on the fluid, so you can throw those big terms out.  Those terms don't enter into the "form drag" since they don't exert a net force on any fluid parcels. If they did, then a fluid at rest would start moving absent any other external forces.

Nope... Just didn't think it through when I wrote it! I realized it 
shortly after but thanks anyway (to you and JM).

Nico.
