First of all, I think the trend concerning the PDO is what is of most relevence with respect to sensible weather, not the absolute value. Secondly, the RONI is nearly dead-nuts on with 2013....and finally, I'm not sure the solar and statosphere differences are really that big of a deal. First of all, that was a very strongly +AO/NAO season, so that wasn't the main hemispheric driver, anyway. Additionally, I have written in great detail about how an easterly QBO near solar max isn't as hostile to episodes of high latitude blocking as some seem to think. We are probably going to see more arctic blocking than we did that year.
Replica season? No....western Pacific is less favorable and CC has continued...but I see no reason why it can't be included in varuious seasonal composites, as it has been, and continues to be.
