| Summary: | <!--!introduction!--> Mesoscale atmosphere-ocean interaction processes in the Arctic, such as marine cold air outbreaks (MCAOs), are often poorly represented in weather and climate prediction models. Yet, the energy exchange associated with these events can have a significant impact on the atmospheric heat and water content, as well as the ocean mixed layer. In the Nordic Seas, where crucial warm-to-cold water mass transformation occurs, MCAOs have a significant effect on the Atlantic Meridional Overturning Circulation. However, the processes through which MCAOs affect this water mass transformation and the ocean circulation remain unclear, with possible competing effects occurring in the boundary currents and in the interior of the Nordic Seas. We investigate the impact of air-sea heat exchange during MCAOs events in the Nordic Seas, shedding light on the role of MCAOs on water mass properties and dynamics. We use a combination of atmospheric (ERA5) and ocean (TOPAZ4, GLORYS12) reanalyses data to ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
