    Looks like the Arctic with low ice and warm surrounding seas will be stormy this winter. We have one stonker that has travelled across the Barents Sea from Greenland at the mo., likely to blow itself out over the Laptev Sea an the next 3 days. Any input here will be appreciated.

    Good thread!

    With the altered dynamics up there we should expect subtle variations in both the weather up there but also the weather 'sent' from up there.

    Maybe not for this 'winter thread' but the prospect of what open water,evaporation and warming may bring a whole new intensity of weather exported south over the summer months (instead of it pasing over low R.H. ice pack!).

    Looks like another storm will be brewing up over Svalbard and the Barents Sea by the middle of next week:

    I hope this works because if it does watch how much snow has fallen since end of September.

    THIRTY DAY ICE FORECAST FOR THE WESTERN AND CENTRAL ARCTIC FOR OCTOBER

    ISSUED BY ENVIRONMENT CANADA ON 03 OCTOBER 2007.

    THE NEXT 30 DAY FORECAST WILL BE ISSUED ON 16 OCTOBER 2007.

    Mean air temperatures were near normal values over most locations

    except below normal over the Coronation Gulf. Freeze-up over the Western

    Arctic will be 2 to 3 weeks later than normal over most locations.

    Forecast ice conditions for October 03rd to October 15th.

    An area of high pressure over the Arctic Ocean will maintain a

    light to moderate easterly flow over the Beaufort Sea and along the

    Alaskan Coast during the period. In addition, a deep low pressure system

    moving from Alaska to the Northwest Territories will bring moderate to

    strong northeasterly winds over the Central Arctic. Temperatures will be

    near to slightly above normal values during the first half of October.

    The main pack of multi-year ice will remain well offshore but will move

    slowly southward during the period over the Beaufort Sea. At mid-October,

    the southern edge of the multi-year ice pack will be located about 140

    miles north of Tutoyaktuk Peninsula and Barter Island and 240 miles north

    of the Alaskan Coast. New with some grey ice will form within the multi-

    year ice pack during the first week of October and thicken to a mixture

    of grey and greywhite ice at mid-October. Bands of very open drift multi-

    year ice will persist along southeastern Banks Island, in western Queen

    Maud Gulf and western Victoria Strait during the first half of October.

    New with some grey ice will develop over northern Peel Sound, western

    Victoria Strait, western Larsen Sound and western Queen Maud Gulf at the

    end of the first week of October. The ice over these areas will thicken

    to grey with some greywhite ice by mid-October. Mostly open water

    conditions will persist over the southern Beaufort Sea, along the Alaskan

    Coast and the rest of the Northwest Passage during the period.

    Forecast ice conditions for October 16th to October 31st.

    Periods of moderate to strong east to southeasterly winds will

    develop over the Western Arctic during the second half of October.

    Temperatures will be slightly above normal over most locations during the

    last two weeks of October. The main pack of multi-year ice will remain

    well offshore over the Beaufort Sea during the period with greywhite ice

    forming between ice floes. New with some grey ice will form in shallow

    bays and inlets along the Alaskan Coast, in Mackenzie Bay and south of

    the multi-year ice pack during the third week of October. The ice will

    thicken to grey with some greywhite ice over these areas at the end of

    October. From Queen Maud Gulf to Peel Sound, new ice will form over

    southern Peel Sound, eastern Larsen Sound and eastern Queen Maud Gulf

    during the third week of October, while the ice will thicken to grey with

    some greywhite ice over the rest of the shipping route. At the end of

    October, a mixture of grey and greywhite ice will be present from Queen

    Maud Gulf to Peel Sound. At that time, new with some grey ice will

    develop in Dease Strait. Bands of very open drift multi-year ice will be

    embedded in the ice pack over western Victoria Strait and along

    southeastern Banks Island. Mostly open water conditions will persist over

    the rest of the Beaufort Sea, off the Alaskan Coast, in Amundsen Gulf and

    Coronation Gulf during the period.

    Nunaavut is the area to the north west of Hudsons Bay, the warning is in association with a weak area of low pressure moving eastward, the thermal gradiant looks pretty weak, thus minima are the story as opposed to snow.

    Woo Hoo! It works!, How do we keep it going? :doh:

    Looks like the cold air from last week's storm is blocking the advancement and intensity of the storm over the Barents Sea from progressing, but this should increase the cold air in longitudes from 0 to 90 deg

    post-7302-1191944278_thumb.png

    But it may dump a lot more snow! ;)

    Its a big learning experience, and I just don't know how the Arctic Winter will pan out yet - ice recovery or not.

    Brilliant! Look at the sea ice recovery - I wish there was a way to keep the GFS 500hPa animations going in a permanent link for the NH, is there a way?

    post-7302-1193238635_thumb.png

    The most active systems seem to wind themselves up over Greenland, and proceed over the Kara sea, filling on the way. There are also big N Pacific systems centred over the Bering Sea that run out of steam as they hit Alaska.

    The last few weeks have shown more of the same, with the Greenland and Norwegian Seas getting most of the action, with an intense weekend in prospect:

    post-7302-1194957920_thumb.png

    BFTPs loop shows nice snow buildup over all of Russia, in Eastern Europe and Scandinavia, and in North America from coast to coast above 50 deg N. The sea ice is rapidly closing in the Chukchi and Kara Seas, so we are now waiting for The Barents and Bering seas to show any ice formation. I don't think we will have much longer to wait.
