  1. problem being that we have not been seeing sustained cold across the basin? If we believe PIOMAS then the ice is even thinner than the past years where we saw ice export of the thicker ice?

    If we believe the 'Strat Warmers' the the polar vortex is just about to be blown out of the basin with little chance of it re-forming before the spring equinox is up on us?

    With FY ice increasing it's share of the basin (again) it is a concern to have read how much more energy this ice type allows into the waters below compared with the older ice. To me it means a threefold increase in what energy used to get into the basin even before the ice has gone. If this is the mechanism that allows the mega algal blooms to develop then we have an even darker surface to concentrate this energy on early in the season further speeding up the loss of the FY ice.

    Last year we 'apparently' saw 3m+ of Canadian Archipelago FY ice go by Aug. How much 3m FY ice do we have in the basin? To me it seems a safe bet that an average year will again take the vast majority of the F.Y, ice. Add into this the amount of 'multiyear ice' which is FY ice welded onto the base and we may be looking at very thin multiyear ice come Aug. Any recurrance of the cyclone will surely mangle this ice leaving only fragmented ice throughout the basin.

    Fragmented ice exposes more surface area (to it's mass) than solid ,contiguous ice and so melts out far faster.

    That is an 'average year'. what if we get an above average year???

    Hi Gw smile.png to be honest, I must admit, i've been posting the 2m temp maps of the arctic myself, over the past few weeks. I must say, that even i've commented on how much milder, than it should be, it has been up there based on the maps :/ There has been a distinct lack of the deeper blues (-40c and below) that i would associate with the arctic.Must admit i feel a bit lost with it all.

    Here's todays chart.

    Still the milder stretch in the middle with the colder air dispersed either side of the continents.

  2. Latest PIOMAS update, not looking good at all...

    Just a temporary thing from the winds. What it does show is the big difference that a long spell, especially seasonal, of southerlies through Fram could make with holding that thicker ice in the basin. Unfortunately, those types of weather patterns have been largely absent since 2005.

    Thanks for your reply BFTV smile.png It's really frustrating to see that all the arctic needs initially, is a change in wind directions. I must admit i would never of thought a southerly wind would in fact be an asset up there for the ice. Meanwhile the ice condition in general is still quite appalling sad.png interesting times.

    Look at the current ice speed and direction :) Wouldn't it brilliant if it was like this till the end of winter?

  3. Has the ice always shifted in the way it does towards the end of that animation or is it just me? I can't remember seeing such a large lurch away from the east of Greenland... That said I rarely remember what I did earlier these days.

    Quite dramatic to say the least smile.png I'm used to hearing that the ice is disapearing down fram so is it not good that it is going the other way now? albeit temporarily smile.png Can you give us any more info on that BFTV? smile.png

  4. Based on the daily extent values, the mean annual extent in 2012 was the lowest on record at 10,417,502km2. This is 1,768,180km2 lower than the average of the first 10 years from 1979-1988 (12,185,682km2).

    Hi BFTV :) Not looking good for the max this year? The area has dropped to over 1 million below again as well hasn't it?

    Have I mis-interpretted what occured to the North of Greenland?

    Take a look at the above image, blow it up and focus on the 'open water' to the north of Greenland?

    That is ice below the water is it not? Have the southerlies just flooded the region?

    Just a question but, If it is indeed just flooded and not a gaping hole smile.png would that infact help the thickness of ice there if the flood waters were to freeze on top? smile.png Wildly out there suggestion admittedly ph34r.png but any merit to that question?

    SSt's aren't looking as disastrous in the basin but just look at the Huge sst anoms still around svalbard? and the nw coastal area of norway/ icelandbad.gif
