bluewave Posted March 24, 2012 Share Posted March 24, 2012 Our local temperatures have been tracking along with the Arctic since 2000. We have been registering a large amount of record high temperatures across our area at the same time that the Arctic has been experiencing record warmth there. http://www.americanw...out-since-2000/ http://data.giss.nas...Ann.Ts+dSST.txt The extended warmth, especially since 2010, has been occurring during the same time that the Arctic has been experiencing their two warmest years on record. 2004 was one of our cooler years since 2000 which was also the coldest in the Arctic during this time frame.

winterymix Posted March 24, 2012 Share Posted March 24, 2012 Bluewave: intriguing post but I think you should want to geographically define the Arctic. Specifically, in the last-cited map (Jan to Dec 2004), the anomalies are mottled with some areas of persistent warmth very close to areas of persistent cooling and those transition areas within the geography of "the Arctic". The broader message is important; an anomalous large scale trend is upon us and perhaps it is hard to know if equalizing anomalies in the cooler direction will unfold and if so, how equalizing and how persistent. Case in point, the profound March anomalies now seem to be regressing toward the mean. Link to comment Share on other sites More sharing options...
easternsnowman Posted March 24, 2012 Share Posted March 24, 2012 Since the late nineties temps have gotten much warmer in the east so there is something to this. Link to comment Share on other sites More sharing options...

Case in point, the profound March anomalies now seem to be regressing toward the mean. I am using the temperature data from NASA GISS ( 64N-90N). I was able to find a chart to go along with the numerical data that I provided in the original post. http://data.giss.nasa.gov/gistemp/tabledata_v3/ZonAnn.Ts+dSST.txt Link to comment Share on other sites More sharing options...
bluewave Posted March 24, 2012 Author Share Posted March 24, 2012 You can also see the warming effect with a positive or negative AO. 2010 -AO 2011 more positive AO More positive AO since September 2011 Link to comment Share on other sites More sharing options...

I also made a comparison using the six warmest and coolest years since 2000 using the NASA GISS Arctic temperatures. Six warmest Arctic years Six coolest Arctic years Link to comment Share on other sites More sharing options...
