Extended Data Fig. 6: The model-generated internal and forced PDO patterns appear similar to observations and each other.

a, Regression of observed SST on the observed PDO index. b, The average regression pattern of the internal PDO SST pattern across all ensemble members. In each ensemble member, we calculate the regression of SST on the PDO index at each grid point. We then average these regression patterns across the full multi-model ensemble with each member weighted equally. c, Regression of ensemble mean SST on the normalized, ensemble mean PDO index from the all-forcings simulations.
