![]() ![]() Strong low pressure over the Gulf of Alaska resulted in a circulation pattern in the eastern Bering Sea that brought cold air from the north. The sea level pressure pattern for November featured widespread low pressure over the Atlantic side of the Arctic and extending into the Barents and Kara Seas, paired with a moderately strong Beaufort Sea High (Figure 2c). Conversely, temperatures over southwest Alaska and the eastern sector of the Bering Sea were as much as 6 degrees Celsius (11 degrees Fahrenheit) below average (Figure 2b). Yellows and reds indicate high air pressure blues and purples indicate low pressure.Ĭredit: NSIDC courtesy NOAA Earth System Research Laboratory Physical Sciences LaboratoryĪir temperatures at the 925 millibar level (about 2,500 feet above the surface) were well above average north of the Canadian Archipelago, by as much as 6 degrees Celsius (11 degrees Fahrenheit).
