Abstract: In simple GCMs, the time scale associated with the persistence of one particular phase of the model?s leading mode of variability can often be unrealistically large. In a particularly extreme example, the time scale in the ...

Abstract: The authors investigate the dynamics of zonal jets in a semihemisphere zonally reentrant ocean model. The forcings imposed in the model are an idealized atmospheric wind stress and relaxation to a latitudinal temperature ...
