I'm no meteorologist, but am interested in weather - particularly extremes. I have just read the link below, but have no idea of the article's validity, so I'd like any thoughts.

With all the talk of 'unprecedented polar conditions' leading to this begs the question: is this how other extreme winters were caused, e.g. 1947, 1963 which were presumably much worse than winter 2018 is ever going to be!

Thanks.

Jan
