Arctic sea ice / Re: The 2019 melting season
« on: August 19, 2019, 01:16:16 PM »
Southward movement has restarted in Nares and between some of the Islands of the CAA: Borden, Ellef Ringes, Meighen and Ellesmere, also the South end of Parry Channel
Map here:

Wind has been light over the last few days (Gif is for 15th to 18th Aug) so this is this is mostly ocean current driven.

South of the floes is clear blue ocean, so the potential for export over the next 6 weeks (2 w past the expected minimum date) is high.

My naive reaction is that those anomalies around the CAA suggest that a complete melt out is possible there.

The thickness in most of the CAA is already very low according to PIOMAS, so I agree.

The tidal flow is generally from North to South through the CAA, so the CAA gets filled with floes from the CAB. Recently the wind has been from the South, preventing the usual South going export, but it looks like that has restarted.

The breakup of the first channel from CAB to Parry Chanel occurred at the end of July, the earliest on a tie with 2012. The export flow has continued into October in the past.

CAA - There is cracking in the landfast ice all the way to the CAB. That's early, but not unprecedented. As near as I can, visibility permitting, the same event happend on these dates in the recent past:

2018 Aug 15
2017 Aug 22
2016 Between July 30 and Aug 04 (thick cloud)
2015 Jul 31
2014 Sept 12
2013 between Aug 11 and Aug 22 (thick cloud)
2012 July 28

VBC has split in half.

Here's the throw,
Here's the play at the plate,

Look like new ice is entering from the North.

Oops, I should have cited the source - NSIDC.

I’m not calling the maximum, I’ll leave that to a more frequent poster, only that I think it is more likely than not the max is already past.

Because:

Mar 1st is the long term 1981 to 2010 peak
2019 would have to climb 0.113 M km2 to exceed the Feb 25th extent
DMI shows above average temperature for most of the arctic
The Climate re-analyser 3 day forecast shows above average temperature for most of the arctic, though not on the Atlantic periphery

It's not over yet, 2018 extent is still flatlining. It's now lower for the day of year than any year since 2000 except 07 and 12.

Breakup in the Perry Channel. Clouds make it hard to see the extent. Polar view does not have an image of the area post breakup yet.
