Atlantic Ocean Variability in a Changing Climate: Observations, Modeling, and Theories V Posters

Session ID#: 92622

Session Description:
By redistributing a large amount of heat and salt, the Atlantic Ocean significantly impacts regional and global climate over a wide range of time scales. In particular, the Atlantic has seen strong variations in the ocean heat and freshwater content over the past couple of decades, as well as in the uptake and storage of anthropogenic carbon, which has been attributed to changes in the ocean circulation, e.g., those related to the Atlantic Meridional Overturning Circulation (AMOC). However, the mechanisms through which the ocean circulation changes (e.g., in the mean state and variability) and impacts the climate system (e.g., via a series of modes of variability such as the Atlantic Multidecadal Variability, the North Atlantic Oscillation), as well as the feedback, remain poorly understood. This session invites submissions that advance our understanding of the Atlantic Ocean variability, the role it plays in the atmosphere–ocean–sea-ice system, and its impact on the future climate. It aims to bring together recent progress in understanding the circulation and climate variability in the Atlantic sector from paleoclimate, historical and future perspectives. Studies utilizing observational, modeling and/or theoretical frameworks are all welcome.
