I will examines how different atmospheric regimes affect the ocean heat storage and overturning in the North Atlantic Ocean and the wider climate system.The prevailing view is that much of the ocean variability in heat storage in the North Atlantic is understood in terms of slowly varying climate modes, i.e. fixed pressure patterns such as the North Atlantic Oscillation. Instead we wish to explore how the ocean heat uptake and overturning is controlled by the position and frequency of individual weather systems, in particular atmospheric blocks, which determine the path of the jet stream.

The jet stream can be in a variety or regimes, such as involving undisturbed flow, wave-like undulations, persistent deflections to the south or north linked to atmospheric blocks.

The ocean storage of heat and ocean circulation is strongly affected by the atmospheric forcing. In particular, stronger Trade winds enhance the northward heat transport into the subtropical ocean, while stronger heat loss over the Labrador Sea enhances the ocean overturning and northward heat transport into the subpolar North Atlantic [Williams et al., 2014].rtainty makes this topic so fascinating.
