BLI snowman Posted March 30, 2016 Report Share Posted March 30, 2016 I remember Mark Nelsen posting a map that broke the states into regions. If I recall 2014 was the hottest on record for the Willamette Valley and Puget Sound regions. It was certainly the hottest July-September on record, regionally, which is more representative of that summer anyway, since the warmth was centered on JAS. Yes, if you look at JAS then 2014 rises to 2nd hottest for WA and 4th hottest for OR. Of course with that metric 2015 drops quite a bit thanks to September. Regionally 2014 is the 4th hottest JAS and the 9th hottest JJA. But like you said, the heat was focused on the westside and the Willamette Valley and Puget Sound each had their hottest JAS in 2014 and hottest JJA in 2015. So back to back years with recordbreaking trimonthly summer warmth on the westside. Certainly noteworthy. Quote Link to comment Share on other sites More sharing options...

James Jones Posted March 30, 2016 Report Share Posted March 30, 2016 Since September is as much of a summer month as June around here, maybe it makes sense to look at the warmest June-September periods on record.

The long term, reliable stations in the region with little UHI increase do not show 2014 and 2015 as the top two warmest summers. Whether you use JJA or JJAS.

TT-SEA Posted March 31, 2016 Report Share Posted March 31, 2016 I think the upcoming pattern is favorable to re-assert the warmer than normal waters off the PNW coast. Its already coming back.

Seems to help with a warm summer and I like warm summers. Pretty simple. The SSTA map right now looks much like it did in early spring of 1998. That year... the +PDO hung on a little while longer and we had a great summer. It went fairly negative in the late summer and fall and still screwed us the following winter. Although it was a great year for the mountains. You like 8 months of non-stop rain. Probably will have a repeat next winter! Its all good. I just want a nice summer in between two VERY wet winters. You want rain and cold all summer as well. To each their own. You should move to Juneau.

Looks like 1983 was an extreme situation as well. Not a hard and fast rule either... but its worked for the last 2 summers.Actually, 1983 was also a volcanic year (El Chichón). There's a standard set of processes that occurs during volcanic years that complicates their use as analogs. Fortunately, in the case of 1983, it's a viable analog for other reasons.

For the PNW specifically, the correlation to the PDO and temps is quite strong in the cold season. I've provided the stats that show this many times in the past.The correlations between SSTAs and corresponding temperature anomalies are stronger over the NH during the summer, which makes sense, physically speaking. Why does it matter whether the relationship is causative or correlative? There should be a stronger correlation between the PDO and PNW temperatures during the summer, and I'm fairly certain that's the case looking at the data on the ESRL site. That said, if the winter correlation in the PNW is stronger than the summer correlation, this suggests a common causation between variations in the PDO and PNW climate (low frequency external and tropical forcings being likely drivers). In this case, using the PDO to forecast on a seasonal (or at least a sub-seasona) scale resolution doesn't make much sense, given it'll lag the interdecadal swings in forcing/circulation.

Phil Posted March 31, 2016 Report Share Posted March 31, 2016 In other words, if we have a La Niña/+PDO in September, it is in no way predictive of the nature of the forthcoming winter. This is due to the fact that it takes time to reorganize the thermal structure of the upper ocean, which will respond to/lag the circulatory changes occurring at the surface.
