January 14^th, 2019:

I just wish that it will not play too rough on August and September…

JAXA ARCTIC EXTENT 12,905,748 km2（January 14, 2019）

- Extent gain 102k, 49k more than average gain on this day.
- Extent is 5th lowest in the satellite record,
- Freezing to date from minimum is 95 k (1.1%) below the 10 year average extent gain,
- On average (last 10 years) 85.8 % of the increase in extent from min to max is done.

The outcome from using the 10 year average extent gain from now is a maximum of 14.24 million km2 (360k > 2018).

GFS indicates that overall the Arctic temperature varies from +1 to -1 degrees for the next week or more. This disguises the highly variable +ve and -ve anomalies at various times over the various regions of the Arctic. e.g. the Bering Sea looks like it will have strong +ve temp anomalies for some of the time interspersed with days of strong -ve anomalies.

Gerontocrat, thank you for exposing the "power of the average". It strikes me how this winter the daily data is fluctuating wildly, yet the sum total returns to the decadal average again and again.
I guess the seasonal pattern in the Arctic depends on geography, bathymetry, currents and climate and far less on weather than would seem, and the difference between the decadal averages exposes the accumulated change.

Isn't this the difference between climate and weather?

[Juan C. García]

Isn't this the difference between climate and weather?

There is a big difference between having and average of 0°C on autumn-winter and 20°C on spring-summer, or having -20°C on autumn-winter and 40°C on spring-summer. Of course, both give the average of 10°C on the four seasons.

So, if we have the new temperatures for 30 years, some could say that the climate (on average) is the same, even that the weather is not.

So the question is if the ASI is swinging more abruptly than in the past. From my point of view, it can be happening, but it doesn't matter. The point is that we are getting use to have low values the whole year and we see weakness on the ice that is remaining.

2019 can be the lowest or the 10th lowest on record. But for the first 15 14 days of January, the 2005-2019 are the 15 [years] lowest on record.

The Arctic has changed.

[Tor Bejnar]

So, if we have the new temperatures for 30 years, some could say that the climate (on average) is the same, even that the weather is not.

Per Tamino, in his January 2nd post on 'What is Climate? Really?',
climate is not ever "just the average."

Climate is the probability density function of weather.

The catchy way I like to say it is:

Climate is the odds. Weather is the roll of the dice.

And the odds in January are never the same as the odds in July.

This animation is so messy that I wasn't going to post it, but I think it shows how volatile ice extent/area is over recent years, particularly when the peripheral seas are freezing.

The attached image shows an example of the great variation in temperature anomalies over various parts of the Arctic that seem to be a feature since mid January.

This is one very back and forth freeze season. Lowest on record to 14th to 3rd to 8th and on and on and on

The wild fluctuations are as much the result of wild ups and downs of previous years as it is this year's ice. All such fluctuations might be actual wild swings in sea ice or they might be statistical noise resulting from large sections of ice crossing back and forth across the 15% threshold.

Extent numbers and maps of sea ice are based on interpretations of data and are not understood to be absolute.

I suppose if one had voted that the high would be 14.125 to 14.375 they would be feeling pretty good! hehe

How is the Bering Sea doing compared to last year ?

Bering is on the high side compared to all recent years, though low compared to 2012 and 2013. All in all, seems normal. I wonder if it will go higher in Feb-March, or plateau at current level generating another low maximum. My bet is on going higher.
