There would be a taper zone between 10 and 20 degrees gradually increasing to 1 degree and then continue poleward with 1 degree. The proposed vertical structure is 40 levels with a constant 10m resolution to 210m and then increasing to 5000m supplied by Dave Behinger. This resolution takes into account the need to properly resolve the thermocline and thermocline displacements both in the east and west. It is also suitable for the assimilation of XBTs. Here again Dave has made the topography.
Some considerations are the treatment of the Indonesian throughflow, mininmum depth and smoothing.
Partial bottom cells will be used. This is purely a computational issue the rigid lid should qualitativly give the same results. Again for longer time scales than SI a positive definite tracer advection schem is desirable. The Robert time filter is chosen over the Euler backward scheme to suppress the computational mode.
