There is a factor connecting this winter with 1962-3. In that winter,
I recall that the NE Pacific and Atlantic south of the Grand Banks
had large cold pools which, it was believed at the time, caused a
mild winter over the USA and severe cold over Europe with a high
pressure anomaly over Iceland and low over the Azores during
JAn-Feb.
This year the two areas are warm, the Pacific area particularly so
from well before the start of the winter. The two warm areas have
this year combined to produce a severe winter over the eastern
USA and the stormy, zonal weather across the Atlantic and
Europe.
I noticed in today's paper that Anchorage, Vancouver and Seattle have
all turned a fair bit colder. Let's hope that's the sign of a pattern
change.
In another thread, I mentioned a break in the Californian drought also;
a recent lowering of SST anomalous warmth in the southern Namias area
_may_ also signify a change of type for N America. However, the warmth
south of the Grand Banks still suggests continued cyclonic activity
for the UK.
