We saw this, for example, earlier this winter
when the AO went very negative, we had a Dipole Anomaly, Greenland and the Newfoundland area were very warm, but Europe and the East coast of the U.S. were hit with all the cold air that was pouring out of the Arctic.
Stephen Wilde says: We have seen the jet streams move poleward
when the AO is positive so in the Mediaeval Warm Period we must have had a positive AO despite the more active sun All you are saying is that clearly [«despite»] the AO has little if anything to do with the Sun.
Something puts a lid on the ability of the El Nino to push the jets poleward
when the AO is negative and on recent evidence (ignore your reconstructions) the AO is more negative when the sun is quieter.
We have seen the jet streams move poleward
when the AO is positive so in the Mediaeval Warm Period we must have had a positive AO despite the more active sun because the jets seem to have been even more poleward then than at the peak of the Modern Warm Period (so far).
When the AO index is positive surface pressure is high in the polar region.
When the AO index is negative there tends to be low pressure in the polar region, weaker zonal winds, and greater movement of frigid polar air into middle latitudes.
Are you saying the open Arctic impacts the Arctic Oscillation and
when AO is negative / positive then open Arctic will amplify / detract from AO influence on winter weather in regions of Northern Hemisphere?
When the AO is in a positive phase, sea level pressure in the Arctic is particularly low.
It had a role due to increased ice fluxes through the Fram Strait in the early 1990s,
when the AO / NAO was very positive.
When the AO is negative, the jet stream tends to be wavier, just like the situation we're in now, which favors slow - moving weather systems that can cause floods.
Otherwise, you'll have to wait until May 8, 2018,
when AO International Tennis will release on PS4 and Xbox...
But the biggest downer is
when AO International Tennis just flat out ignores you.

But then
when I computed different lead and lags the strongest relationship was between fall snow cover and the winter
AO.
I think what needs explaining, is why negative NAO /
AO conditions occur
when the solar wind is weak:
If this happens during northern winter, surface pressure falls in the Arctic (rising
AO) the night jet stalls, NOx injection falls away, stratospheric ozone levels increase, the coupled circulation is invigorated and pressure falls at 50 - 60 ° north and this is associated with cloud loss (
when global cloud cover is at its maximum value) and a strong rise in global sea surface temperature.
When depression activity over the Arctic is high, the indices of both
AO and NAO are more easily inclined towards a positive state, with a stronger west circulation around the northern hemisphere and improved temperature isolation for the Arctic region — and that's the real paradox of this story, because positive
AO and NAO are actually associated with milder winters in Europe and for instance the US.
But what I referring to was observationally - based studies that isolate (verify or not) the IPCC's «expected» anthro
AO mechanism and a NET gain
when all energy transfers are considered.
So what comes out of this test is that the
AO climate model driven by a bias - adjusted SST record with reduced variations, produces better land temp estimates than
when it is driven by «uncorrected» SST containing stronger long term variability.
When adding a new coupling link, there is no a priori guarantee of seeing only modest consequences in the
AOS solution behavior.
As you may recall I say that the ocean phases also have an effect so if you have a weak ocean phase
when there are a lot of sunspots the lack of poleward pressure from the weak oceanic influence fails to take full advantage and allows the
AO to remain stronger than it otherwise would be on the basis of solar activity levels alone.
However even in your link
AO was generally positive
when sunspot numbers were relatively high from the 1970's to 2000 which is as I say it should be.
The main discrepancy during that short time span is a high sunspot number around 1960
when we had strong solar cycle 19 but the
AO was negative.
These developments are somewhat antithetical to predictions made in the 90s and 2000s,
when the polar vortex was in a strong phase (positive
AO).
Another interesting thing I found was that
when I plotted ten - year means of GISS
AO temperatures against the SRES watts / sq m CO2 forcings for the two scenarios I got an almost perfect straight - line fit (R = 0.998) with a gradient of 0.55 degrees / watt.
