    Kara sea look set to get a little bit of cold air over it in the next few days before being cut by yet another low pressure system so I imagine ice growth will still be very slow here. 

    Will the Chukchi growth slowdown with that Arctic high blowing less cold air here, one to watch but the Bering Stright does look poised to close over at long last. Still carrying on the trend though of later and later growth mind. 

    Am I missing something? I would expect growth to be rapid it’s not a brief flirtation. Should freeze over completely.

    Aaannnd, the same animation but for the whole month (a larger, better quality version is on the twitter page too)

    Here are the images for today. I'm going to start updating these roughly twice per week from now on.   

    A comparison of the first 13 days of surface air temperature anomalies across the Arctic. The lack of -ve anomalies and the increasingly widespread +10C anomalies of the last 5 years or so is quite so

    It will all depend on the placement of that deep second low, if it stays near the island of Novaya Zemlya(?) then it will be tough too see ice grow as the winds will be coming in off the sea but if it pulls away towards Russia which is kinda what the GFS hints at then ice may grow as the air will be colder and winds coming in off frozen land. The Arctic high may also help with this eventually but in the main, it's hard too see much ice growth in the kara sea occurring in the near future imo.

    It’s going to become very cold shortly that’s most important, prolonged much colder temperatures are expected the refreeze will be rapid I have no doubt.

    Aslong as the second low clears then yes I agree with you. The best set ups for ice formation is cold winds from Russia and Siberia and we will see a little bit of that in the next few days.

    Weekly animation. The Chukchi Sea is quickly filling in and the Bering Sea gained its first substantial ice cover. Growth is slow in most areas, however. Kara is still struggling to gain any ice and continues lowest on record.

    With an increase of 805,000 km² in the last 6 days, extent has climbed from 2nd to 7th lowest on record. This is the highest position extent has occupied since the 28th of June.

    Volume still comfortably second lowest on record. Most of the difference to 2016 comes from Hudson Bay, with the Arctic seas pretty close overall

    2020 extent overview gif, split into the freeze to max, melt to min and freeze to end of the year.
    Can't seem to upload the gif seperately, (might be too big) so here's the gif in a tweet.

    I see the svalbard is lacking in ice again and ice in the Barants looks poor, does make me think there could be a link with Atlantic lows can travel more into the basin when there is open water because there is less severe cold to deflect these low pressure systems away.

    Remember last year saw lots of ice around Svalbard  and that ice remained there right into July but still retreated dramatically into July so if that open water does not close, we could be looking at an very early retreat of ice on the Atlantic side come the summer.

    Ssssshh, you know who! Svalbard is currently buried under 1km of ice??? Don't mention the thaw!🦄:santa-emoji:

    Use the link that was under the image. It says archive in the url, but it provides the latest temps and updated, but only as a single image. You'll notice it says updated Jan 5, so it's definitely up to date.

    Sea ice in the Barents and Kata have been all over the place recently. Huge variations from one day to the next.

    (Animation is too big to upload, so here's the tweet)

    Impressive (though not in a good way) how far north of Svalbard the ice edge is. Remarkable for mid-January.

    Lack of northerlies hitting Svalbard is perhaps the main reason for this, I guess that could mean less fram export but it does mean Atlantification could be extreme again. It was last summer despite a very extensive ice cover over Barants in winter and spring. 

    High pressure looks like being in charge for the foreseeable future, in theory this should mean a build up of ice along the Siberian coastline but looking at the concentrations in the Laptev, the ice does not look thick nor compact too me despite bitterly cold temperatures there at the moment. 

    As for the Kara sea, it should look a bit healthier when the wind direction changes in the next few days surely. The Barants sea will be a real struggle though sadly.

    not really the ice edge was as far north or even further north in 2018,17,16,15,14,13 & 12

    Oh well that's alright then?

    You have looked at the measures of ice Volume passing through Fram in the 70's,80's early 90's haven't you?

    That there once existed a year round 'Ice  Bridge' that hindered ice export? (though 'export it still did!?)

    Was it the 'Odenn' ice bridge (help me out folks?)

    That is within MY lifetime

    In my Dad's lifetime Barentsz was inaccessible even in high summer due to ice conditions (check out the Norwegian Prof, from the late 30's, that attempted such!)

    Now we see how much ice is even present there to even be exported (never mind conditions 'Common' in the 70's/80's/90's as the Arctic bled dry of paleocryistic ice!!!)

    C'mon now C.M., it's all stained glass windowed up isn't it?

    We've done this for over a decade now eh?

    How are things now (tied global temp record with a 'Super Nino') compared to back then?

    This was never a 'competition', for some it was a way of warning of what we were seeing occur? (& where than would end up?)

    That time is done now surely?

    We 'Warners' were correct to 'Warn'?

    Sea ice volume remains 2nd lowest on record, 980 km3 above 2017

    PIOMASAllJanmid.thumb.png.13b64844587270a30e0d6f7d606cf98e.png

    Regionally, 2021 is just as bad as 2017 in the central Arctic, but pulls ahead in the other Arctic Ocean seas (Laptev through to Beaufort) and the Sea of Okhotsk.

      Cold waves hitting Europe continue to threaten growers, is there a link to climate change?

      Much of Europe, not just the UK, has experienced unseasonably cold weather since the Easter Weekend. A plunge of cold arctic air brought by northerly winds early last week brought several nights of frost and even snow across large swathes of Europe, followed by another wave of cold arctic air spreads across much of Europe this week. The frosts causing damage to new growth in vineyards and orchardsa0spurred on by a late March heatwave, the vineyards of France werea0particularly badly affected.
