From recent work the AOC is about 15-sverdrup with 3 going into the Arctic Basin on the Asian side, since warm water is the most likely suspect consider the Pacific water is some 0.8-0.9 sverdrup an input of 30-Twh/year in heat and hydraulically pulls in about an equal amount to compensate as a closed circulation, the basin empties to the Atlantic ccw to influx.
Reducing the Pacific water inflow reduces Atlantic inflow with such evidence it seems it's mandatory, nullschool is still showing waves in the Chukchi Sea ice or not it's allowing waves to record, to me that's incredible heat flow evidence.
Suggest reducing flow through Bering Straits by 1/100th in climate models, add year-round ice in the straits, then polder all of the Chukchi Sea next stage and last stage 1/2 the Bering Sea at the drop off.
Model that for jetstream flow it should turn the Hawaii flow eastward sooner as a cold-forcing the thesis of how it will alter global flow, a key indicator that California gets more moisture in the models.
If models validate the concept as worthy we must create a sea-ice refuge there somehow to forestall what's going on with the warmer, fresher water that this year is pretty obviously too warm with storm winds to allow a normal freeze-up the thought.
