== 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 [[attachment:barbi.tar|source code]] of a numerical implementation is provided. A better (finite element) numerical implementation was developed by Sergey Danilov, AWI, Bremerhaven.

Streamfunction in Sv in steady state in a simulation of the BARBI model with N=0 1/s (a), a simulation with a flat bottom (b), 
and the standard model simulation with topographic variations and stratification (c). Also shown are isobaths (lines).
