We will see if this pattern of a colder Atlantic persists, it's been around for a while now I think, late spring/early summer?

It's been around most of the year, but changed gradually, especially over the last 4 months. It is now considerably further south. Back in June it was around 10 degrees further north, rather more intense, but didn't extend anywhere near as far eastward. In fact at the end of June SSTs were above normal in the eastern Atlantic everywhere from Ireland to northern Spain. It extended eastward in August.

From a purely observational point of view, based on past events, I expect it to drift further south & become less of a feature.

Thought I'd return to this as it's starting to look like the cool anomaly is indeed drifting south and becoming less significant http://www1.ncdc.noaa..gov/pub/data/...vy-anom-bb.gif

The trouble with anomaly maps is they give an impression of a pool of cool water, when in fact the just normally indicate a variance from the normal temperature gradient. Obvious I know, but it is important to look at actual SSTs at the same time, http://www.wetterzentrale.de/pics/Reursst.gif
