Could the PDO be changing to a positive phase?
Values like this haven't been seen for almost 20 years:
http://margaret.atmos.washington.edu/pdo/PDO.latest Could augment the global temperatures caused by the current El Nino conditions. The Global temperatures over the next few months - and indeed in 2015 overall - could be interesting! |

I'm using FF 35.0. Curious. It is a hard object not found 404 with IE & Chrome. Even the truncated to previous directory fails 404 The root server works but a search on PDO.latest gives a PDF document dated 2010 which also fails 404. -- Regards, Martin Brown |

This works - not sure if it's what dawlish wanted us to see. go here :- http://margaret.atmos.washington.edu/ Then click on PDO at the bottom of the 4th column of links. (or go directly here,same thing) http://research.jisao.washington.edu/pdo/ You'll see a chart and the top left link "PDO Index Monthly Values:January 1900-present", takes you he- http://research.jisao.washington.edu/pdo/PDO.latest |

If I am right in this conjecture then it might briefly go above zero but won't be strongly positive for a sustained period for another 20 years or so. There are tidal forces with periods that are multiples of 31 years and 29 years which could play a part driving this. The time series record is too short and too noisy to be convincing but will improve in time. -- Regards, Martin Brown |
