Main Conclusion

The observed interannual variability of the WNPSH is characterized by two distinct modes. The performances of CMIP5 AGCMs in the simulation of two modes are assessed.
The first mode is well reproduced by the CMIP5-AMIP models, suggesting it’s driven by the SST forcing.
The second mode is partially reproduced by the CMIP5-AMIP models, suggesting it’s neither a pure SST-driven mode nor a pure atmospheric internal mode.
