| Summary: | <!--!introduction!--> In wintertime over the subpolar North Atlantic Ocean (SPNA), the strongest surface sensible and latent heat fluxes typically occur just downstream of the ice edge. The recent retreat in Arctic wintertime sea ice is changing the distribution of these turbulent heat fluxes, with consequences for the formation of the dense waters that feed into the Atlantic Meridional Overturning Circulation. Projections of turbulent heat flux over the SPNA are investigated using output from the HadGEM3-GC3.1 climate model, produced as part of the 6th phase of the Coupled Model Inter-Comparison Project. Comparison of two model resolutions (MM: 60 km atmosphere - 1/4° ocean and HH: 25 km – 1/12°) shows that the HH configuration more accurately simulates historic sea ice and turbulent heat flux distributions. The MM configuration tends to produce too much sea ice in the SPNA, affecting the turbulent heat flux distribution; however, it displays improved performance during winters with less sea ice, ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
