Indeed Naut, i ponder what would happen if the prefered route for the jet would be at the southerly extent of current loops....that would effectively make the ferrel cell a polar influenced mechanism.... However, Missouri, I'm sure theres no data to suggest this is a "thing". So two points of stability in the northern hemisphere depending on macro=levels of incoming energy. and a wavy state between them as they switch? Like the Romans, we'll be buying our grain from North Africa? A "thing" from the black lagoon? The reason we have data for historically reconstructing the NAO is because Britain was a sea going people and had a penchant for collecting data. And the NAO as a longitudinal gradient is important to Western European winters. But from watching airmass movements from satellite, there are other north-south (and return) paths in Central Europe to the Med and from the looks of East asia, monsoonal flows and associated water has been incredable this year. Another longitudinal flow. The Chinese were collecting data when the Brits were still herding sheep. If pressure patterns can change between iceland and the azores, they can also change elsewhere around the world in recurring patterns simply not recorded before.

Perhaps in glacial periods the cold attractor gains stability, during maunder minimum there were hot summers and not even close to every winter froze the Thames. Maybe theres alot of chaotic fluttering between the 2 states 🤔

Do you mean paths which flow prefers to take?
Dont know, there appears to be predominant ones in recent years, northerly over western europe bringing pulses of heat to UK, southerly over eastern Europe taking cold to middle east, which i know you've noticed.
These are very extreme however and transitory. Whether they're statistically significant i have no idea.
The US "polar vortex" events are also meridional ones and reoccurring in past 10 years or so.

South Eastern Australia is forecast to enjoy 4 days of blizzards in the mountains, with up to a metre of snow.
The snow is expected to fall at the far North of NSW on higher ground, as well as towns like Oberon and Orange, and on the nearby hills and perhaps some of Melbourne's suburbs on Saturday.
Following hard on the heels of a major cold outbreak in South America, global warming in action.

[[Solar Plasma Temperature is plunging – should we worry? Guest Blogger / 2 days ago Guest post by David Archibald wattsupwiththat.com/2020/08/23/solar-plasma-temperature-is-plunging-should-we-worry/]]According to one of the references in the link above, the temperature of the Southern Hemisphere has fallen by 0.6degC in the last two weeks. This might go some way to explaining the recent extreme low temperatures in Australia, South Africa, and particularly S America. In the latter case, Southern Brazil has just shattered its long term low temperature records, and Argentinian authorities estimate that somewhere between 30 and 70% of the flocks and herds of sheep and cattle in Patagonia have been killed by extreme low temperatures and meters of snow. Anyhow, what I found interesting about the temperature graph – apart from the SH rapid fall – was that no similar effect was occurring for the NH. Might it be that the difference is that the SH is in winter, and inclined further away from the Sun. Therefore, might cosmic radiation have a larger [seasonal] impact? If this very tentative hypothesis has some basis in reality, some time in the next few months the NH will follow suit.

Bingo! In 10 years of reading and studying "this stuff", at first read this has got to be the best, most direct, readily understandable proposed explanation of climate dynamics I have ever seen. Thank you Acid. Obviously a modeler that has not succumbed to the "dark side". Now to dissect and capsulize it for my internal storage.

I agree it is a good explanation for the layman like me but it seems like the website hasn't been updated for 6 years?

Can't find him on net either....but site shows a 2020 at bottom, still being paid for 🤷🏼♂️.
Meanwhile....UK, a couple of sites have recorded lowest August temps for over 30 years and its heartwarming to see BBC etc publicising this fact.

Even cold-hearted bastards can have their cuddly moments. Editor was probably just "pissed" though (in the English sense).
