A good post in WUWT describing mechanisms for D-O events and the Arctic Iris. The follow up comments are also very useful.

JAXA down to second lowest today. The forecast L.P.'s entering the basin might see a period of both melt and compaction over the coming week so expect both area and extent drops to continue.

Even when the temperature is below freezing the water still needs to build a layered arrangement whereby the colder water does not descend and that means a large volume of water has to be cooled to metres of depth to create that arrangement. Looking at Cryosphere the refreeze point is about a week away now.

But a lot of the water is already in contact with ice - hence at freezing temp already.
Incidentally, the ice on SE Hudsons Bay has only just finished melting.
Observers at a safe distance suggest refreeze will be fast!

Observers at a safe distance suggest refreeze will be fast! I am assuming the way it works is that it begins freezing up in the main pack while still melting much further out. From watching cryosphere for a few years, the whole pact goes a solid purple colour on cryosphere once it is ready to show an increase. Currently the western arctic is about a week from that happening. The refreeze might be a rapid one once it begins because there is a large section of open water surrounded by ice in the western arctic and I am supposing that will fill in fairly quickly. Canadian ice service is also showing that as well as large amounts of open water as well as entirely ice free areas in the northwest passage.

www.wunderground.com/blog/JeffMasters/comment.html?entrynum=3100Nice to read jen agreeing with my take on post 07' 'multiyear ice' in there? Another recent paper linking low ice areas with winter buckles in the Jet and PV migration? Seems that this nino winter across the U.S. could be scuppered by the low ice on the pacific side of the basin ( the post 2012 set up) . That would be human destruction of the arctic trumping Natures stronger driver?

Doesn't anyone research anymore before they confirm how foolish they are.
