![]() We also discuss the potential impacts of surface temperature anomalies for the atmosphere, including the North Atlantic Oscillation and European heat waves contrast the behavior of the Atlantic with the extreme warm surface event that occurred in the North Pacific over a similar timescale and consider the possibility that these events represent a response to a change in atmospheric planetary wave forcing. Here, we review the role of air-sea interaction and ocean processes in generating this cold anomaly and place it in a longer-term context. Ocean temperature extremes, commonly referred to as marine heatwaves ( Hobday et al., 2018 ), impact marine habitats and ecosystems through thermal stress. Most notably, a large region of persistently low surface temperatures accompanied by a sharp reduction in ocean heat content was evident in the subpolar gyre from the winter of 2013-2014 to 2016, and the presence of this feature at a time of pervasive warming elsewhere has stimulated considerable debate.

While some of these phenomena have been explained by analysts and experts, there are still some interesting occurrences underwater that can’t really be rationalized.
