Thanks for that, Philip; must've been quite a bit of work. It would
be
interesting to know what the temperature regime has been in the last 50
yrs
over western Russia or say, Finland. From your figures, an even more
dramatic
warming than over the UK would seem likely.
Could you do (or have you done) a similar exercise for July? In my
21-yr
record here in Surrey July is now quite markedly the driest month (5.6% of
the
total) of the year. Yet in the fifties such a notion would have seemed
preposterous. The night-time French imports of thunderstorms which one
could
happily rely on a few times a year after a hot spell in the 50's and 60's
are
now pretty well unknown. These facts make me think there has been quite a
change in the mean circulation for July and I wonder if this could be
confirmed.

I have produced the mean monthly charts for July but I haven't looked
at the detail yet. A cursory "eyeball" examination indicates comparatively
little change. Feb, Apr and May are the big ones. I'll get round to doing
them month-by-month.
