The authors gratefully acknowledge Robert Tomas and Adam S. Phillips (NCAR) for their help in generating and making available model output. We would also like to thank Ben Kirtman, Walt Robinson, and Jerry Meehl for their insights. Thanks also go to Peter Gent for the reminder of how inappropriate the “ENSO like” terminology is with respect to mechanisms of low-frequency Pacific climate variability and change, and to Dallas Murphy for his encouragement. We acknowledge the various international modeling groups participating in Coupled Model Intercomparison Project Phase 3 (CMIP3). AC is funded by an NSF ATM grant (AGS0946225), a NOAA grant (NA10OAR4310204), and a DOE grant (DESC0004897). NCAR is sponsored by the National Science Foundation.
