El Nino 2015 / 2016

[Ground Scouring]

The CanSIPS, NMME, and CFSv2 models are suggesting that the current +PDO, which has persisted for two years, will continue through the fall (and perhaps early winter) of 2016. Such a long +PDO stretch without a single monthly negative reading would be unprecedented since the early 1940s. We've already seen 25 consecutive months of positive values. Is there any climate feedback that could favor more frequent/intense or long-lived +PDO cycles in a warmer world? Obviously, they've occurred many times on (and off) record.

Not sure about climate impacts on PDO. PDO has an impact on global temperatures but is hard to separate from ENSO, with temperatures surging since the switch to +PDO/+ENSO.
