PL001:
Advances in our understanding of the meridional overturning circulation in the South Atlantic


Session ID#: 27827

Session Description:
The meridional overturning circulation (MOC) is a key component of the climate system because of its role in redistributing heat, salt and carbon around the globe.  The tremendous growth of the MOC observing system over the past ~15 years has led to new discoveries about the spatial and temporal variability of the MOC and how it influences coastal sea level, weather, and climate. Models and observations have shown that the water masses formed in remote regions are significantly altered as they transit the South Atlantic by processes such as mixing, advection, and local air-sea interactions.  These modifications may lead to changes of the MOC strength and variability, and thus of the meridional heat and freshwater transport changes.  In this session, we focus on recent results gleaned from observing systems in the South Atlantic, including moored, satellite, shipboard, and Lagrangian measurements. Recent model results on the MOC in the region, are also welcome.  Together these observations and modeling results can provide a comprehensive view on South Atlantic MOC (SAMOC) variability. We encourage abstract submissions on new MOC-related findings in the South Atlantic, as well as on recommendation and/or design studies for the future evolution of the SAMOC observing system.
