With the 15th-19th GFS this morning being more depressing than
yesterday's (albeit still with a block, but too far to the east to
affect anywhere west of Germany) it seems that the only thing of
interest this month would be to achieve the possible "record" above. I
can't think of a January which had *non stop* weather which was both
mild and wet - all examples I can think of either had a cold, dry
interlude or a mild but dry interlude (years like 1990 and 1995 spring
to mind here)

I'd be interested to see Philip's westerlies index for this one (if
I've got the terminology correct) !

I've made up a little graph showing the variation of the circulation
indices from 2002 to 2006 inclusive. It might take a few moments to
get your head round for anyone not familiar with the indices, but it's
fairly simple really.

The indices are in millibars and are based on the British Isles lat/long
block (i.e. 50-60N 00-10W), and the lines show 30-day moving
means.

The graph ends with the 30-day period 2-31 Dec 2006
