BARBI

BARBI is an acronym for BARotropic Baroclinic Interaction. It is a model with simplified circulation dynamics based on the vertically averaged equations of motion for a baroclinic ocean with topography (Olbers and Eden, 2002). The source code of a numerical implementation is provided. A better (finite element) numerical implementation was developed by Sergey Danilov, AWI, Bremerhaven.
