North Pacific Ocean Grid
Here's a plot of the model domain.
- Resolution: 40-16 km
- Area: 20S-66N and 100E-80W
- Parabolic Splines density Jacobian Pressure Gradient
- Closed boundaries on all walls
- Large/McWilliams/Doney interior mixing
- LMD convective mixing due to shear instability
- LMD convective nonlocal transport
- LMD diffusivity due to shear instability
- KPP surface boundary layer mixing.
- Laplacian mixing of tracers and momentum
- Mixing of tracers along geopotential surfaces
- Mixing of momentum along constant S-surfaces (soon to change)
- Fouth-order Akima horizontal and horizontal advection of tracers
- Third-order upstream bias advection of momentum
- Surface net heat flux and salinity corrections
- Forced with climatological winds
- Code is ROMS 1.8, enhanced with the
Scalable Modeling System
(SMS) from the
Forecast Systems Laboratory (FSL)
to enable it to run on their distributed memory Alpha and Intel
supercomputers. Dan Schaffer,
at FSL, did the SMS coding.
After a 90 day test run of this grid, the initial spin-up of such features
as the Kuroshio and various equatorial surface currents can be observed in
this plot of surface velocities and Sea Surface Height.
