PL11A:
The Driving Forces of the Ocean’s General Circulation I


Session ID#: 36803

Session Description:
The focus of this session is on the processes that facilitate the closure of the ocean's general circulation. The processes driving the upper and lower branches of circulation, and interconnecting them are of interest. In particular, the impact of changes in these driving processes on the circulation, thereby on the climate system, on a wide range of time scales will be part of our focus. Example topics of interest include: high latitude coupled dynamics, interior and deep ocean turbulence and mixing, boundary processes and global scale energetics and/or water mass analyses. We encourage contributions that not only focus on physics of processes, but also on their role and interconnections in the large-scale circulation.
