One of the only regions that have been observed to cool over the past century is the North Atlantic cold blob just south of Greenland. In our recent paper, we analyse the cold blob or “warming hole” and the processes that contribute to its creation and evolution. While sea surface temperature has been reliably observed, the underlying mechanisms of changing ocean circulation are only sparsely meas ...[Read More]
How Climate Models helped uncover the mechanisms behind the North Atlantic Warming Hole
Schematic illustration of the drivers of the warming hole. The AMOC (Atlantic meridional overturning circulation) is indicated by red arrows and the gyre circulation by blue arrows Shading represents the surface temperature trend of the 1pctCO2 increase per year ensemble.
