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!
