JAXA ARCTIC SEA ICE EXTENT 14,012,340 km2(February 10, 2020)
I hope none are in too much distress from a day's missing Jaxa Update.
- Extent loss (a -ve gain) on this day 21 k, 31 k less than the average GAIN (of the last 10 years) of 10 k,
- Extent gain in this freezing season to date is 10,048 k, 790 k (8.5%) MORE than the average last 10 years gain to date of 9,258 k.
- Extent is 13th lowest in the satellite record,
- Extent is 641 k more than 2017
- Extent is 363 k MORE than 2019
- Extent is 353 k (2.6%) MORE than the 2010's average.
- Extent is 134 k MORE than the record low maximum of March 2017.
- on average 94.1% of extent gain for the the season done, 29 days on average to maximum.
We are into the period when on average daily extent gains are low but highly variable.
Projections.
Average remaining extent gain in the last 10 years from this date produces a maximum of 14.60 million km2, above the lowest in the satellite record in March 2017 by 0.72 million km2.

Freezing Outlook?
GFS says overall Arctic temperature anomalies in the range from +0.9 to +0.0 celsius over the next 5 days.
The Bering /Chukchi/Okhotsk, and Canadian far North mostly very cold to extremely cold.
The Atlantic Front remains and will remain a battleground between warm southerlies heading up from the Atlantic and cold Northerlies out of the CAB & Russia, and the southerlies perhaps reaching the Barents Sea on occasion.
At the same time significant +ve anomalies occasionally entering the Kara/Laptev from interior Western Russia.
A messy picture as the warmth from the rising sun fights the bitter cold of the Arctic Ocean (as we are now 50+ days after the winter solstice).
Overall I now have not a clue (nor did I ever), as to whether the outlook is more favourable or not favourable for the recovery in sea ice to continue in the peripheral seas. Beware the vagaries of winds, warmth & cold.
