Deep water formation sites impact climate patterns in North Atlantic.
The AMOC has two modes of variability: the Trend Mode and the AMO. The Trend Mode is linked to deep water formation in the Nordic Seas and a North Atlantic AMOC cell at 50° N, while the AMO is related to deep water formation in the Labrador and Irminger Seas and an overturning cell at 20° N. This suggests that increasing atmospheric CO2 affects the AMOC through deep water formation in the Nordic Seas, impacting the North Atlantic.
