I wonder whether people felt the same in 1939-40, 1981-2 and 1990-1? They all occurred just after the peak of a solar cycle.
1947 was just three months before the peak.

I do know what you mean though. There's a fair list of "Hale" winters to choose from too. Just thought I'd throw those examples out there.

I don't know what has happened to me recently but my scepticism has deepened. People are blaming solar activity for this winter not delivering so far. Solar activity is lower than a number of recent peaks. Low solar activity alone doesn't explain the great winters above.
We are told sudden stratospheric warming events increases the chance of northerly blocking and cold episodes.
I go along with that but it doesn't explain a number of cold outbreaks. Where was the SSW that resulted in late Nov-Dec 2010? The coldest part of winter 1976-77 occurred before the SSW.
I would say that a SSW gives you a chance of breaking out of a weather pattern but if you are in a cold pattern and you want to maintain it, would you want a SSW to occur?
Then there is OPI and SAI. It seems that things are not going according to plan here. The trouble seems to be the low pressure anomaly over the Barents-Kara region.
NAO, AO, OPI, SAI, PDO, AMO, SSW, MWW, ENSO.....it's an alphabet soup of complexities.
