79-80, 96-97, and 01-02 all had similar characteristics to 97-98 fwiw. (maybe StrongEl Nino in another dimension?)
(It also seems to default to +EPO with -NAO pre-potential)
74-75 I think was a La Nina with +PNA. La Nina's are pretty rigid because they strengthen the mid-latitude jet, less land-ocean variance. I'm just saying, in the subsurface this one is not a La Nina.
A lot of people don't know this, but 95-96 was not a La Nina as per ENSO subsurface, 0.0. Plus 90-91,91-92,92-93-93-94-94-95,97-98 were all +ENSO 7/8 years. 95-96 was +PNA.
raindancewx might think this is interesting, after 2 years of +IO up to Japan in August (2020-2021). NAO signal is pretty interesting, Siberia doesn't often dominate.
I've seen it a million times, predicitions for a +AO August, based on June, July run forwards puts it on models peak Aug 22-Sept 7, while veering weeks before.
big time -NAO still.. should be interesting
^ Solar max ascending underperforming, same point in cycle
Just to give it away though, it should be like this
Look at this.. Pacific ridge or 588dm 594dm is way north all the way through August. Next 15+ days.
