1.Global
Model - (Wright, Lu): OPA model, with non-eddy resolving (~ 2 deg) resolution, currently
using climatology forcing, soon to start realistic forcing. Plan is to simulate
global ocean circulation of past 50 years with data assimilation. Model to
provide boundary forcing for basin models.
2.North
Atlantic Basin Model – (Wright, Thompson): OPA model,
¼ deg resolution, with realistic forcing and data assimilation
for past 10-20 years. Model to
provide boundary forcing for regional models.
3.EAST
(shelf) Regional Model – (Hannah, Davidson) – OPA
model, 1/12 deg resolution, designed to run in operational mode
(embedded within the NWA model or quasi-stand-alone model (using BCÕs
from NA Basin Model).
Will run for hindcast/nowcast/forecast mode and in a ecosystem mode
for seasonal and longer time scales. Ultimately 1/36th deg zoom.
4.Northwest
Atlantic Regional Model – (Davidson, Hannah) OPA (existing model
basis - POM) model, with ¼ deg resolution and focus on operational
forecasting development. Ultimately 1/12th deg resolution.
MERCATOR OPA Model:
(lat,lon,z), hydrostatic, nonlinear primitive equation model, with rigid lid (free-surface being added). North Atlantic resolution ~ 1/3 deg, 43 levels in vertical, assimilation of SSA, SST and
profile data.
