All of those following winters were severe in the East in one way other another: 1976-77 cold and huge lake effect snow, 2002-03 cold and constant snow including PD2, 2014-15 Long Island/New England and NYC "near hit" blizzard and Boston annual record snowfall. WOW. Now we factor in ENSO, QBO, etc. for further clues... This is encouraging news. I like how there have been several bouts of strong blocking so far. Hopefully, that will continue into and through much of the winter. Arctic sea ice extent is running some 680,000 square kilometers below previous record low figures for the current date.

billgwx Posted November 2, 2016 Share Posted November 2, 2016 Here's a chart showing rankings of October Eurasian Snow Cover Advance (which is neither total Snow Cover Extent, nor the portion of the October advance south of 60N, which is Judah Cohen's formal definition of SAI) since 1967, as well as the ENSO phase going into or during the winter immediately following. Data courtesy of the Rutgers Global Snow Lab. Until I can figure out how to get the portion of this south of 60N, am using as a proxy for SAI. Shades represent ENSO phase which I hope is obvious (reds/orange = weak/moderate/strong Nino, blues/cyan = weak/moderate/strong Nina, grey = neither). Lots of Ninos at the top and bottom of the rankings I'd say, and look where 2016 ended up... Link to comment Share on other sites More sharing options...
billgwx Posted November 2, 2016 Share Posted November 2, 2016 Here's a chart of the numbers by year for those who want to see what happened in past years following moderate/strong Ninos, followed by neutral or weak Ninas: Link to comment Share on other sites More sharing options...

Eskimo Joe Posted November 21, 2016 Share Posted November 21, 2016 Arctic sea ice continues to be anemic, no matter how you slice it. Amazing how growth continues to be so sluggish despite 24-hour darkness: Link to comment Share on other sites More sharing options...
