Abstract
Connections between decadal changes in the tropical Pacific mean state and ENSO decadal modulation are examined using three runs of a CGCM. The differences between the three simulations, i.e., a standard coupled model (one AGCM is coupled to a single OGCM) and two interactive ensemble models (six or twelve AGCMs are coupled to a single OGCM), are confined to the amplitude of internal atmospheric variability. All three simulations have the same tropical Pacific basin scale SST mode that dominates the low frequency variability, which is identified by the first EOF mode. This low frequency mode is largely independent of the simulated ENSO and is neither a residual of the decadal ENSO modulation nor does it produce any low frequency modulation of ENSO. The analysis presented here suggests that this low frequency mode is stochastically driven by atmosphere noise.
