•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)
