Before anyone imparts even more received wisdom about SSWs - and this
appears to be - may I refer to a post my Martin Rowley, which got me
interested in SSWs and for which I've thanked him before. Thanks
again! Before anyone goes accepting that received wisdom, I would
heartily implore you to read the papers in Martin's MetO library list.
Some are very relevant. None go to the extremes that Will does, or
Michael Fish and all are *very* cautious in linking SSWs with
individual surface conditions, except in very well developed major
events. This one is not.

This is very much a minor SSW event, as there has been no reversal in
stratospheric winds, rather than a major one. Several papers
investigate major events. None investigate minor ones, as far as I
know.

And of course, these couplings have been studied by researchers in
Russia, Japan, China and France, to name but four, and to do an
exhaustive search would require looking for works published in those
languages - it has been an 'active' area of research over the last 10
years or so.

A word of caution: don't rely on a 'general' internet search for this
type of subject: you need to interrogate specialised catalogues, such
as this one, or the AMS etc.

As it is a .sci newsgroup, I think anyone proposing these kind of
links should give an academic assessment of probabilities, based on
research and not upon what they think should be the effects of an SSW
event. I will happily change my mind and learn if I'm wrong.
