Hydrostatic version of DieCAST ocean model
(non-hydrostatic results can be found
here).
1100km (longitude) by 400km (latitude) region is modeled
Equally spacing vertical and horizontal resolution
(100m and 10km, respectively)
The northernmost latitude is 500m deep.
A 1 % shelf slope brings it to 2200m maximum depth
at the latitude 17/40 of the way to southern boundary
Inflow is imposed from the northern boundary
(bottom concentrated and geostrophically balanced with ~5Sv total inflow)
and ~11 Sv from the eastern boundary (representing westward
flow from the northern part of the North Atlantic gyre)
The southern boundary is closed. The western boundary is open, using
upwind-based outflow conditions modified to give no net inflow into the
modeled region.
constant horizontal viscosity and diffusivity of 50 and 10
m^2/s, respectively and Pacanowski and Philander parameterization.
(background values of 0.1 cm^2/s).
These conditions give typical cell Reynolds number O(100).
