Short summary
The heat content in the subpolar North Atlantic is in a new phase of long-term decrease from the mid-2000s, which intensified in 2013–2014. We focus on the pronounced heat content drop. In summer 2014, the MOC intensity was higher than the mean (2002–2012) and the heat transport was also relatively high. We show that the air–sea heat flux is responsible for most of the intense cooling. Concurrently, we observed freshwater content increase mainly explained by the air–sea freshwater flux.
