A53D:
Climate Variability and Ocean-Atmosphere Interaction over the North Atlantic III Posters

Submit an Abstract to this Session



Session ID#: 30747

Session Description:
Climate variability in the North Atlantic has important implications for rainfall, air temperature, hurricanes, and sea ice. However, the mechanisms that cause this variability remain an active area of research. The ocean-atmosphere coupling driving North Atlantic variability and how faithfully it is simulated by models is still under debate. For example, studies suggest that models misrepresent the ocean-atmosphere heat exchanges, thereby underestimating internal variability. The relative roles of tropical and extratropical SSTs in driving variability are also uncertain. In this session, we welcome observational and modeling studies investigating North Atlantic variability in the past, current and future climate. Contributions on the following topics are encouraged: 1. The role of local atmosphere-ocean-sea ice coupling in North Atlantic climate variability (e.g., AMV, AMOC, Gulf stream, tripolar SST pattern); 2. Assessing the climatic impacts of North Atlantic variability on sea ice, hurricanes, precipitation, including interactions between the North Atlantic and other ocean basins, (e.g., between AMV and the Pacific); 3. Understanding North Atlantic climate change from paleoclimate reconstructions; 4. Contributions of internal and forced climate variability and implications for future projections (e.g., hiatus); 5. Predictability
