Results from Lorenz coupled models
Coupling a fast and a slow Lorenz model, we can do
breeding of the slow modes
Valid for other nonlinear approaches (e.g., EnKF) but
not of linear approaches (e.g., LVs and SVs) which are
dominated by the fastest component
Can be applied to the ENSO coupled instabilities (Cai,
Kalnay and Toth, 2002, for the Zebiak-Cane model)
We have also had promising results with the NASA
NSIPP coupled ocean-atmosphere GCM (Yang, Cai and
Kalnay, 2003)
