Phil Posted October 10, 2019 Report Share Posted October 10, 2019 1978-79 was surrounding a solar maximum as well. A real lack of blocking with that one.Well, if you treat everything equally, of course you’ll have a hard time picking up the effects of solar forcing on PNW climate. But nothing works in isolation in the climate system. If you filter for ENSO/QBO, the solar effect is quite substantial..stronger than ENSO alone, actually. There are only a few years since 1950 that have managed to buck the correlations.

BLI snowman Posted October 10, 2019 Report Share Posted October 10, 2019 I didn’t read his post, but I’d argue that the system’s response to solar forcing has indeed changed (and substantially) since the 1930s. These correlations are never static..they vary just as the climate system itself does. Jared seems to believe they are static, at least as far as it fits his confirmation bias (i.e. 2008-09 was cold and low solar so this winter must be as well). And if the correlation isn't represented in a particular year then it's because it predates some system overhaul and the results are rendered irrelevant to now. 1 Quote Link to comment Share on other sites More sharing options...
snow_wizard Posted October 10, 2019 Report Share Posted October 10, 2019 As for the solar / blocking connection....obviously nothing is true all the time and the same is true in regard to high solar producing a lot of blocking. A lot of the current theories on it are derived from behavior during the Maunder Minimum which seems to have featured an abnormal amount of blocking over the NE Pacific and NE Atlantic. In recent times the past four solar mins have all treated us well (that's counting last winter as one of the two deepest solar min winters in this cycle). All I can say is given the current combination of low solar and observed weather I would bet my next paycheck we will have at least one good month this winter. This combo is pretty rock solid. 1 Quote Death To Warm Anomalies!

Phil Posted October 10, 2019 Report Share Posted October 10, 2019 Those epic PNW years during solar maximum are almost always +QBO and neutral/-ENSO. It actually works out very consistently. But good luck trying to score with an El Niño/+QBO during solar maximum. And for the same dynamic reasons, the combo of -QBO/Niño in solar minimum often works out better than niña/-QBO in solar maximum. Constructive interference vs destructive interference.

It’s definitely not a 1-to-1 correlation and it never will be. I think there’s evidence that, for now, solar minimum generally promotes a system state that is more favorable for PNW winters. But that hasn’t always been the case..and it won’t always be the case.

And are you disputing the fact that low solar promotes high latitude blocking? Because if you are, you are fighting a much larger battle than me. The winters that surround the solar minimums the last four decades were 1975-76, 1976-77, 1985-86, 1986-87, 1995-96, 1996-97, 2007-08, 2008-09, and 2018-19. The winters that surrounded the maximums were 1978-79, 1979-80, 1988-89, 1989-90, 2000-01, 2001-02, 2013-14, and 2014-15. I bolded the years that to my knowledge seemed to feature a substantial amount of regular arctic air transport into the lower 48, which corresponds with anomalous blocking. Looks about even to me.

The solar minimum years you referenced had much more -NAO, while the solar maximum years had more -EPO.

I have the monthly data here http://sidc.be/silso/datafiles#total 1978-79 was definitely higher solar (235.9 in January vs. 266.9 max in September), and the whole 1978-82 period was pretty pronounced high solar, as was 1988-92. (last truly historic midwinter arctic airmasses in the PNW) The sun entering 2007-08 was quite dead already, we saw a 5.4 spot count in April 2007 and a 1.5 in October.
