Worth noting that the global climate was about half a degree lower back then
than it is now, thus it is a bit more notable since the anomaly relative to
the current climatology is greater.
The blocked pattern with a prevalence of easterlies and absence of westerlies
in winter in our small part of the globe might be something that will become
more common as a result of climate change associated with global warming. I'm
not saying that will be the case, only that we should not close our minds to
the possibility. Our "traditional" westerly-dominated winter weather has
resulted in a winter climate that is very anomalously warm for our latitude. It
seems to me that any change to local circulation patterns in our region in
winter is more likely to lead to colder winter weather than milder winter
weather as any such change would most probably reduce the occurrence of mild
W-SW winds. Only time will tell but, as we are finding out this spring, an
absence of westerlies can have a very profound effect on our winter and spring
weather/climate.

From my experience it seems the influence of this pattern stretches quite far down into France. The last couple of summer breaks I've had in the Montpellier area have not been *hot* like they were years ago - the locals seem to think that the Mistral blows more often than it used to, even in high summer. On departure at the end of last August we left Avignon in gale force winds. Despite the sun being out it just wasn't that warm. Obviously the last couple of years could be a blip and normal service is about to be resumed?
