That is our Greenland high!....doing its job. A bit further south than normal tho.

Interesting. I hadn't looked at the Greenland High and the Icelandic low for awhile. Winter is winter here, whether it is -20F or +20F. The Icelandic low could very well be playing out in the warm weather Europe is having. Attachments:

Well, I'll be. Normally the Greenland High is at the southern tip of Greenland, with a western bias this time of year. Maybe that large high ISN'T the Greenland high....but sure looks like it, but in wrong place.
Interesting!

And Sig ... where do / did you get that graphic??

And Sig ... where do / did you get that graphic?? That warmer water comes from up near Svalbard I reckon. You can see that southbound current on the animations I havnt had time to do of late... +1 Sig. ...do source of graphic pls!

Ahh yes ... it's an anomaly ... but while the Atlantic is turning anomalously cold, why is this area anomalously warm??? Warmer water might account for lower pressure in the Icelandic low, which might account for the continuing positive NAO. But ... are we looking at geothermal heating??? These anomalies appear to be greater than those along the northeastern coast of the US. You'd think that someone would discuss this on the net.

Anomalously colder water in the North Atlantic should theoretically deepen the high pressure zone ... but the warmer water off of Iceland seems to be enhancing the Icelandic low??? That means that the NAO should stay positive?

That means that the NAO should stay positive? While temps in Arctic are still warmer then average, would we not expect water heading south from this area to be anomalously warm? Anomalously warm does not necessarily mean heated, just above average for tome of year compared to last 50/60 odd..

I still suspect the gulf stream is being slowed by interuption by the Labrador current being closer to the surface, this increase in ssta would them be concentration of heat rather the propagation......

Dang.........I don't remember the source anymore. Part of my reading. Thought it was an excellent graph, so saved it to my climate files. Does someone see something wrong with it that I didn't pick up on?

Broke a record today. 83 degrees F at 3pm in Houston, Texas. It's actually miserable with the humidity. I have actually turned on the A/C to dry out the house and make it less humid.

Does someone see something wrong with it that I didn't pick up on? Where do you pick up your data on the geographic extent and strength of the Azores High and the Icelandic Low? A particular site?
