Default November 2004: synoptic overview

The Azores High was displaced north-eastwards and was
centred at 47N 13W (i.e. SW of Scilly) at 1026 mbar. The
Icelandic Low was scarcely detectable (1007 mbar), and
the main low centre in the sector was deep in the Russian
Arctic at 994 mbar. There was also a shallow low 1010
mbar between the Azores and Bermuda. Over the British
Isles mean sea-level pressure ranged from 1012 mbar in
Shetland to 1024 mbar at Scilly and Valentia, and the
mean flow was WNW-ly.

The main anomaly centres we
+12 mbar sea-area Shannon
-12 mbar in the Russian Arctic
-6 mbar between the Azores and Bermuda

Over the British Isles anomalies ranged from +5 mbar
in Shetland to +11 mbar on the west coast of Ireland.
The anomalous flow was NW-ly roughly north of
latitude 54degN, and NE-ly to the south of it.

In the last 50 years only November 2001 was
more anticyclonic over our lat/long block.

CET (prov) 7.7ºC (+0.8 degC)
EWP (prov) 51.8mm (52%)
EWS (prov) 51.5 h (78%)

It was the driest November by this measure since
1988, and the dullest since 1997. Valley (Anglesey)
had its dullest November since the station opened in
1945. Locally in northeast England it was the driest
Nov since 1958.
