I brought this up on the previous page, but the only info I found was from DT, and he has some of the years wrong. I will look at the links you provided. What I recalled was- wrt La Nina winters- there is a correlation to cold eastern US when there is a very negative QBO during winter, specifically during a weak Nina. It appears we are heading towards a weak Nina for fall/winter, but not so sure the QBO is going to cooperate(looking at current trends), so this may not matter.
