Quite Ian. The gradient of contrast is certainly more of interest. Certainly some exceptionally deep lows on a few model runs of late though thankfully they have not really ventured out of FI with fairly standard autumnal fayre prevailing.
In terms of SST's, it is also important to note the waters surrounding our very shores are slightly above average. Nothing significant but enough to balance out much of any cooling of air that has occurred further west in the Atlantic. Putting the two together, the resultant upper air temperature is unlikely to finish off far from normal in my view. Maybe it will strengthen again in to the winter, who knows. However if the cold pool strengthens again next summer, may the point about the importance of freshwater melt from glaciers and ice in the arctic, namely Greenland be further emphasised?
Anyway, not wishing to derail the topic here but perhaps important to highlight this to provide context and understanding.
