JAXA ARCTIC SEA ICE EXTENT:  10,174,699 KM2 as at 04-Dec-2020

- Extent gain on this day 27k, 48 k less than the average gain on this day (of the last 10 years) of 75k,
- Extent gain from minimum on this date is 6,620 k, which is 301 k, 5% more than the 10 year average of 6,319 k.

- Extent is at position #2 in the satellite record

- Extent is  237 k LESS than 2019,
- Extent is  146 k MORE than 2016,
- Extent is  550 k LESS than 2012
- Extent is  503 k LESS than 2007

_____________________________________________
On average 64.0% of extent gains  from minimum to maximum done, and 97 days to maximum

Projections. (Table JAXA-Arc1)

Average remaining extent gain (of the last 10 years) would produce a maximum in March 2021 of 13.73 million km2, 0.14 million km2 below the March 2017 record low maximum of 13.88 million km2.

I attach the December monthly average graph based on actual data to Dec 15th and assuming 10 year average sea ice extent gains to the end of the month.

The resulting extent of 11.11 million km2 would be 2nd lowest in the satellite record, 0.11 million km2 above the record low of Dec 16, and 0.31 million km2 less than Dec 19.

I added the monthly extent value for November 2020 into my long-term plot where I calculate the extent anomalies from 1979 up to now.
The average (1979-2020) November extent is now 10.45 M km². November 2020 had an average extent of 8.99 M km², which is 1.46 M km² less than that long-term average.
The rapid freeze-up in November reduced the anomaly we saw in October from the long-term linear trend line. The difference of the actual month from that trend line is -0.36 M km² (calculated from the linear trend line this October should have been at 9.36 M km²).
The slope of the long-term linear trend line has become not changed since October (-0.0560).

In addition I present the volume anomaly graph (second graph, click to enlarge). It looks much smoother than the extent anomaly graph.

On average 73.0% of extent gains  from minimum to maximum done, and 85 days to maximum

Projections. (Table JAXA-Arc1)

Average remaining extent gain (of the last 10 years) would produce a maximum in March 2021 of 13.98 million km2, 0.11 million km2 above the March 2017 record low maximum of 13.88 million km2.

I was thinking about how low the maximum could be, and now start to think about how high the maximum could be.

The strong clockwise winds assciated with that very large anticyclone squatting on top of the Arctic ocean has pushed ice westwards along the Siberian coast. As a result sea ice area in the East Siberian Sea is down by 83k in the last 7 days.

This, and the recent reduction in the very high Greenland Sea area and extent, are the only exceptions to the general rapid increase in extent and area.
