Under Development

• 2-way coupling between ocean and atmosphere circulation models – put the O in COAMPS

• Couple wave models with ocean and atmospheric circulation models

• Automate flow of data and model results from one model to another – DIOPS for waves

• Integrate sediment transport models with coastal circulation models

• And I haven’t even talked about ice modeling!

Surface Drift Modeling

• Coupled operational models for wind, waves and 3D currents now exist, and we can now build (and assess!) an operational surface drift model.
