Deep solar minimum and we are tracking at the third lowest extent this week.

That, in itself, would be nothing out of the standard norm in fairness.

According to the JAXA monitoring service: https://ads.nipr.ac.jp/vishop/#/extent the 2019 Arctic Sea Ice Extent has pushed above the 2010s average for the first time since March 14th this year. This puts current extent at the fifth lowest in the satellite recording series that began in 1978.

Are there thickness comparisons from the other low SIE?

Sea Ice down the west coast of Greenland between Newfoundland looking very healthy at the moment and only getting better over the next couple of weeks as serious cold continues to be ejected here from the polar latitudes.







There will be a significant advance here beyond the norm.

One of the perks of the polar vortex being so strong is it locks the cold air in the higher latitudes, mostly it can't escape - it just spins and spins and does wonders for sea ice formation.

Northern hemisphere temp anomaly for the first 10 days of January from 1979 up to the present year.



(Climate Reanalyser)

So far, the mean temperature over the NH for this opening period of the year is running the 2nd highest on record, and only a few nths behind that of 2016, which remains the highest in this particular series. Although still running well above average, Arctic temperatures are running at their lowest since 2014 for the same period.

Edit, black line is the 10 year running mean.

Interesting that very cold air has been locked in the Arctic resulting in Greenland lowest ever temperature, you'd think that at some stage in the next few months the Jet will buckle and allow this frigid air sink south into the mid-latitudes. I'm going for one very cold spell in mid-february

The cold air is staying locked in the Arctic this year, while this may be responsible for a mild winter across Europe, it certainly bodes well for the Sea Ice extent there.

As of yesterday, the arctic sea ice extent is at 13,382,493 km2 - making it the 13th lowest in the Satellite series which began in 1979.

It bucks the trend of the last seven years which have seen consistently dropping extent values for this date.

Also of note is the high position of 2005 and 2006 (6th and 2nd) for this date.

Ice extent growth has been quite high for several weeks now and if this continues it is possible that this year's winter maximum will come in closer to values recorded in the 2000-2009 period as opposed to the 2010-2019 period.

Interesting times.

Arctic Sea Ice continuing to perform well. Yesterday's extent was 13,491,629 km2 which is closing in on the all time low maximum of ~13,880,000 km2.

Interestingly, yesterdays extent beats every year of the last decade (2010-2019) for January 24th and also beats 2005 and 2006 by 122,436 km2 and 513,319 km2 respectively.

This maintains 2020 as the 13th lowest on record.

The 2020 season is 174,746 km2 and 180,763 km2 behind 2007 and 2009 respectively so if this season continues to perform well it might edge ahead of these years in the coming week or two.

Arctic sea ice extent continues it's impressive season (impressive against the backdrop of recent years) with the figures rapidly growing again following a pause for a few days.

Extent is now 14th lowest on record as of yesterday's figures at 13,939,559 km2.

This figure means that it has now surpassed the maximum extent figures for 2017 and 2018 - meaning that if melting began tomorrow, 2020 would be the third lowest maximum on record.

However, given the performance of this season thus far and on average 33 days left of ice gains to be had, it is highly unlikely that 2020 will feature in the top five of lowest maximums on record (since 1979 when satellite records began).

Another metric is Sea Ice Area that is used to measure the performance of arctic sea ice. As of Wednesday, this area was ranked 12th in the satellite record and continues to perform well.

This has been a quite extraordinary Winter for Arctic Sea Ice. If 33 days are left it could be over 14.5 million by max. But for some reason I fear Summer will take it all back...or maybe not
