I recall reading that during February 1947 high pressure persistently
stretched all the way from Scandinavia to northern Canada, completely
reversing the normal wind direction at our latitude all the way across
the Atlantic.


Have a peek at http://www.wetterzentrale.de/topkarten/fsreaeur.ht
ml - the "kartenarchiv" - at '47 and '62-3. Also '65, mid-January.


Thanks for the reminder of that archive. The chart for the 22nd
February, 1947 is one good example. Mid-January 1965 has some
interesting charts, but it doesn't seem to fall into the same category.
