GCM projections for the Pacific Decadal Oscillation under greenhouse forcing for the early 21st century
Abstract The climatology and hydrology of western North America display strong periodic cycles which are correlated with the low‐frequency Pacific Decadal Oscillation (PDO). The PDO's signature is seen throughout the entire North Pacific region, with related significant associations to hydrolog...

However, not all the models showed a consistent shift to negative PDO conditions.
