Take a look at

compared to
http://weather.unisys.com/surface/sst_anom.gif

Yes, the latter is just for 1 day, whilst the former covers a week, but the difference has been there all week, so the latter would show a very similar picture averaged over the week.

This is something that has long concerned me, how different sites show such a different results. It's not simply using a different'norm' as the patterns of cold & warm are often different.

Any feedback welcome (the other Graham?)

Penzance has done well for sunshine this morning, currently close to 13C. St Ives has done similarly well http://www.nci-stives.org/weather/Cu...antage_Pro.htm Once again a different world inland at Camborne. The top of the Lizard has a cloak as well.

Anyway, lovely wave again today. Now several days of clean surf for enthusiast with a winter wetsuit

I cannot find the anomaly, wrt what/when, on the page behind the unisys one

From the !ast conversation we had about the warmer anomalies just off the eastern seaboard of the US, we more or less concurred that a probable cause was a lack of dissipation and a "bunching up" of the flow of the warm gulf stream current due to cold water disruption and flow diversion/slowing... Hence the localised warming in such a pivotal area. This was/is backed up by the less obvious colder zone to the west of Europe.
Eventually the concencus was that the gulf stream would slowly flow along a more southerly !attitude...say towards Portugal for example.
The time frame for this action is not clear, as there are various challenges in the model physics to predict with temporal accuracy.
The impacts of all this on places such as Iberia and N Africa could be as large as thoose for NW Europe... But obviously in very different ways.
