We have conducted an all - sky survey for more than 94 % of the whole sky during cold phase of AKARI observation in 2006 Feb. — 2007 Aug.. (arxiv.org)
Significant enhancement in low level cyclonic vorticity and mid-troposphere humidity during La Niña years compared to El Niño years when the PDO was in warm phase, rather than the PDO was in cold phase leads to this difference. (kaltesonne.de)
This is what happens in our model events pictured above: during cold phases in Greenland, oceanic convection only occurs in latitudes well south of Greenland, but during a DO event convection shifts into the Greenland - Norwegian seas and warm and saline Atlantic waters push northward.
