Sam and all:
The link provided by Sam to the UWash imagery has expired.
If you are looking for the current link, go here:
http://www.atmos.washington.edu/~ovens/loops/
And scroll down to where you see "North Pole View" and immediately under that section is the "250mb wind/height" product that shows the jetstream so nicely.
Looking for winter weirdness 2014
There has been some stuff in the past 2 months that could be linked to erratic jet stream behaviour - which in turn could be influenced by Arctic sea ice loss - like a series of storms battering Europe's Northwest, such as the St. Jude storm at the end of October, followed in December by Xaver, ...
One of the great things about this blog is that there is so little energy put into complaining or kvetching about the denial-sphere.
I'd personally hate to see what could be the most public manifestation of this blog be diminished by what would amount to name calling 'the other side'.
Typhoons and Cyclones in the Indian Ocean and West Pacific have person names appropriate to Asia, Hurricanes in the East Pacific have names appropriate to Central America. North Atlantic Hurricanes have names appropriate to North America and the Carribean.
Thus I do not think there is anything 'politically correct' about giving Arctic Cyclones names from the languages of Arctic people's, in fact it would fall very much in line the convention and thus, I believe, give the practice added credibility.
I will be surprised if the ICC get back to you with a definitive answer Neven, I suspect they will say something like 'Sure, we really don't have a say in it'.
I would humbly suggest that a small group of folks here put together some lists of names to use and then submit those to the ICC as well just to see if they have any objections. I really doubt they will, but the gesture will no doubt be appreciated and it will help if someone comes along and tries to use the names against us.
The Naming of Arctic Cyclones
The Arctic is about to welcome another big cyclone. Though probably not as large, intense and long-lasting as last year's Great Arctic Cyclone, it is rather intruiging to see a cyclone of similar magnitude occur so soon after the last one. It makes one wonder whether the Arctic will be seeing mo...
I meant to include a link to a Canadian Inuit dictionary we might be able to use, though I would suggest taking words from all of the indigenous polar peoples.

I would submit that there need not be a difference between Great Arctic Cyclone and Persistent Arctic Cyclone.
The purpose as I see it would be to identify a 'season' for the cyclones based on historic data and I think the melt season, with the acknowledgment that this season is Nader a state of upheaval, and then come up with criteria to declare some a cyclone, either by barometric pressure and organization and position with the Arctic Circle.
Then we simply start naming them in Alphabetical order as they do with Tropical varieties.
I would suggest five lists of names from A-Z perhaps with an indigenous Arctic heritage or based on Arctic places, and with an appended year so we need not worry about debates on 'retiring' names of notable storms since we can propabably all agree that from here on out, they will all be notable.
As the first cyclone of the 'season' year appears to be revving up, I propose a name of:
Kinaktok-2013 (Kinaktok means Sharp)

I'm basing this simply on intuition and nothing really concrete aside from the assumption that there will be a recovery after last years big drop.
Crowd-Source Prediction of September Sea Ice Extent (July report & call for August predictions)
In mid-June through early July, participants on the Arctic Sea Ice (ASI) blog posted 82 individual predictions for the mean NSIDC September Arctic sea ice extent. The median value of these 82 predictions was 3.2 million km2, with an interquartile range (approximately the middle 50% of prediction...
It is only going to get more and more interesting as things progress. Thank you for another great update.
PIOMAS July 2013
Another month has passed and so here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center: The slow start of this year's melting season has had a dramatic effect on sea ice volume. After goin...
At risk of feeding the troll... perhaps if you're going to connect the Russian meteor explosion to Arctic sea ice cracking you should investigate whether there was any cracking caused by nuclear detonations of similar magnitudes and similar or lesser distances in the past.
I think you will find that if there was a significant link between atmospheric detonations in the kiloton range and Arctic ice fragility, science would have noticed it in the past 60 years.
Crack is bad for you (and sea ice)
The previous pun - cracks of dawn - was wearing off, and the comment section was getting full, so here's a new pun and blog post dedicated to the cracking event that started in the Chukchi and Beaufort Seas a couple of weeks ago, and then moved on to the multi-year ice against the Canadian Archi...
Tenney: you need a script for that... Ill work on something. Might take me a few days though, got a lot on my plate.
Open Thread February 2013
The previous open thread has gotten full enough, so here's a new one. We might want to kick off with this animation made by commenter A-Team: His comment: Don't miss this -- it's happening right now, by the hour -- so head on over to 80N 150W. A huge fracture has been opening a bit east of B...
What is the link for that imagery? (In this post) Thanks!

I mostly lurk, but just wanted to say this blog and its regular commenters continue to be simultaneously baffling, fascinating, and terrifying. Thank you, sort of.
2013 Open thread #1
I was planning on writing posts more regularly, but reality forbids. So here's an open thread for all of your off-topic banter. source: Space Daily Will be back next week when I get an Internet connection in our new apartment. There's plenty to write about: that science report, the lower albe...
Just a thought in relation to the talking points (i know i know)... are these graphs available for the Southern Hemisphere?
...... perhaps I can stare at them for awhile and convince myself it'll all be alright.....
Cheers.

PIOMAS October 2012 (minimum)
We already knew a few weeks ago that the PIOMAS sea ice volume record had been broken, but with the latest data release by the Polar Science Center at the University of Washington we now know the minimum sea ice volume for 2012, as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation...
We've had a strong ridge of high pressure over us here in the Pacific Northwest of the US/Canada for what seems like forever for this time of year. It's also sending all the sub-tropical (colloquially know here as the Pineapple Express) rain and storm systems into Alaska and northern Canada.
I am trying desperately to convince myself that the persistence of this pattern has nothing to do with lack of Arctic sea ice.
Someone reassure me please! lol
ASI 2012 update 11: end or beginning?
During the melting season I'm writing (bi-)weekly updates on the current situation with regards to Arctic sea ice (ASI). Central to these updates are the daily IJIS sea ice extent (SIE) and Cryosphere Today sea ice area (SIA) numbers, which I compare to data from the 2005-2011 period (NSIDC has...
I'm looking for the tweet now... has he deleted it? When was it tweeted?
Joe Bastardi found a cherry
Now that fake skeptics have dropped the IMS sea ice extent chart to call the results of this stunning melting season into question, Joe Bastardi comes up with another try (hat-tip to Chris Biscan) to imply that the melting season is over, something that is wanted so desperately by fake skeptics ...
Excellent thanks.
Record dominoes 8: NSIDC daily sea ice extent
There are several scientific organisations that keep an eye on the Arctic sea ice cover and put out graphs to inform us of the amount of ice that is left. You can see most, if not all, of them on the ASI Graphs webpage. I expect the record on most of these graphs to be broken in weeks to come. -...
quick question (hopefully).
What day was the record set in 2007?

On the note of 'this has happened before' indeed it has. I use this handy writing I received in a response from the NSIDC back in 2007. I had asked when the last time it was that the north pole was ice free.
.....
(ybp=years before present, CE="Current Era" Gregorian calendar years)
260,000,000-20,000,000 ybp: no sea ice
20,000,000-2,500,000 ybp: possibly some sea ice
2,500,000-130,000 ybp: sea ice during glacial periods, possibly ice-free during interglacials
130,000-100,000 ybp: possibly ice-free during last interglacial
100,000-10,000 ybp: last glacial period, ice-covered year round
10,000-7000 ybp: peak of current interglacial, possibly some ice-free (at least seasonally) years
7,000 ybp - 900 CE: cooling trend, likely sea ice throughout
900 CE - 1300 CE: medieval warm period, possibly some ice-free periods, but unlikely
1300 CE - present: definite year-round ice cover
Peeking through the clouds 5
Commenter dabize has sent me the latest 'declouded' version of the False-Colour Composite images Environment Canada makes of the LANCE-MODIS satellite images. They give us an excellent view of week to week changes that are blocked by cloudy conditions in the Arctic. Changes in the ice pack reall...
Never, I just wanted to give you a quick thank you for the link to the MODIS imagery which is exactly what I was searching for.

I'm sorry I've been trying to figure it out for a while now but I have yet to figure out what website these near-real time MODIS images are obtained from. I've been through the MODIS site a million times and have never found these 'tiles' or anything approaching what is here.
Could someone provide a direct link to where these are downloaded? Thank you so much
Chris
Our beloved ice pack
People who have kids probably know that feeling when their kid has a fever and they watch him/her for a while at night to see how he/she's doing. That's what I felt when dabize sent me his latest declouding art, a composite image from the LANCE-MODIS satellite images (click for a larger version)...
