The trajectories to SHEBA ship show the air from all levels coming from the Beaufort Sea to the east spiraling around the high pressure system. This was expected since the high had not moved its position in several days.
The trajectories to Barrow show all air coming from the east. The surface air came from the Beaufort Sea and the northern Canadian Islands cycling around the high pressure system. Other levels, 1.0-3.0 km, show air coming from the Alaskan coast of the Beaufort Sea to the east. The higher levels, 6 and 9 km, trace back to Juneau and the Canadian coast on the Pacific Ocean.
