Extended Data Table 1 Details of the 34 models

From: Increased variability of eastern Pacific El Niño under greenhouse warming

  1. The final four columns show the longitudes (° E) of the monthly maximum zonal wind-stress (Tauu) anomalies and SST anomalies in the EP and CP patterns, averaged over 5° S–5° N, for the 34 CMIP5 CGCMs, each forced under greenhouse gas concentration scenario RCP8.5. The first 17 models listed produce a reasonably large |α| and a nonlinear PC1–PC2 relationship (Fig. 1c, d). The zonal wind-stress anomalies associated with the EP and CP patterns are obtained by regressing monthly anomalies onto the monthly E-index and C-index, respectively; the SST anomaly pattern and centre are identified in a similar manner, except using the December–February averages of the E and C indices and SST anomalies. ‘sst’, ‘τx’, ‘τy’, ‘so’ and ‘T’ in the third column indicate SST, zonal wind stress, meridional wind stress, ocean salinity and temperature that are available, respectively. The 17 non-selected models are shown in grey. ‘NaN’ indicates data not available.
