Arctic Sea Ice Extent, Area, and Volume

Recommended Posts

Nice graphs...and for those interested in AK weather & climate, that Alaska-wx blog website is great. Wow, nearly every single day from Nov 2017 - Mar 2018 was above normal in Barrow (and these are recent normals, i.e. 1981-2010)...and many of those days were way way above normal.

Perhaps it's not too surprising, as the persistently low amount of ice north of Barrow over the past 10-15 years significantly moderates the temps in Barrow due to E or NE flow...but still.

Models are showing a reverse dipole for the remainder of June....if that sticks, then we're prob out of any top 3 running this year. Unless we get an obscene pattern in July....2015 was able to make somewhat of a comeback in this manner.

It's been tough to bet against the reverse dipole pattern since June 2013.

Update on SIA (sea ice area).....here is how other years compare to 2018 (i.e. a -542k on 2007 means that 2007 had 542,000 sq km less area than 2018 on this date)

2007: -542k

2008: +163k

2009: +721k

2010: -217k

2011: -263k

2012: -664k

2013: +124k

2014: +152k

2015: -57k

2016: -424k

2017: -13k

 

As you can see, 2017 is the closest match right now...though 2015, 2014, 2013, and 2008 weren't far off. That group of 4 right there shows how things can still change a decent amount....years like 2008 and 2015 still finished pretty low while 2014 and 2013 were the top 2 highest area minimums in the post-2007 era (2009 was the highest minimum extent though....and you can see how much area 2009 had at this point compared to those other years). We'll see how the next 10 days goes, but even by now, the contenders were already separating themselves from the pretenders.
