[ADS NIPR VISHOP (JAXA)] Arctic Sea Ice Extent.

January 14th, 2019:
     12,905,748 km2, a century increase of 101,818 km2:o  ;D
     2019 is now the 5th lowest on record.
Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

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 Arctic is playing with our feelings  ;)
I just wish that it will not play too rough on August and September…

True that. 2019 is gonna be an interesting year. Perhaps one of the unforgettable ones

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.
______________________________________________________________________
ps: *The 2010's average figure I use in the attached table excludes 2019. I exclude 2019 (from all JAXA and NSIDC tables and graphs) so that the difference of the current year with the 2010's decade to date average is not modified by the current year data.

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?

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.

Per Tamino, in his January 2nd post on 'What is Climate? Really?',
climate is not ever "just the average."
Quote
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.
Arctic ice is healthy for children and other living things.

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.

Thanks, Juan. A stinking cold or a dose of 'flu is just an annual event that gives me an opportunity to moan and whine - "Woe is me, etc etc".

Weather - By the looks of it Little Old England is going to get a bit of the results of the SSW and PVS as the rest of the month unfolds. But nothing like Central and Eastern North America and Central Europe.

Is it 'flu or just a stinking winter cold?
But I am dragging my tortured body to the computer.

should you like to reduce your energy footprint and relieve your tortured body i recommend to move south, at least that's what i did for that matter, leaving my most beloved home in prague to find a new one in "andalucia" at least as far as my physical presence is concerned, paper-wise i'm still chinese LOL

JAXA ARCTIC EXTENT 13,206,730 km2(January 20, 2019)

- Extent gain 57k, 35k greater than average gain on this day.
- Extent is 7th lowest in the satellite record,
- Freezing to date from minimum is 8 k (0.1%) below the 10 year average extent gain,
- On average (last 10 years) 87.9 % of the increase in extent from min to max is done.
- On average (last 10 years) 50 days to minimum (11th March)

The outcome from using the 10 year average extent gain from now is a maximum extent of 14.32 million km2 (440k > 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.
