Global teleconnection patterns shaping climate variability and change

Session ID#: 257425

Session Description:
The global Oceans from the tropics to polar regions drive teleconnections that shape climate across the globe. In the last decade it has become recognized that tropical basin interactions are crucial to explaining interannual variability across the tropics, including the El Niño Southern Oscillation. Such interactions are found to play out on longer timescales, for example involving Pacific Decadal Oscillation, Atlantic Multi-decadal Variability, and the Atlantic Meridional Overturning Circulation. Climate in extra-tropical and polar regions are remotely influenced by atmospheric tropical teleconnections. More recently, it has been suggested that changes occurring in the polar regions exert influence on tropical regions, through both oceanic and atmospheric processes. Such interactions are key to understanding how climate responds to changes in external radiative forcing, which may in turn influence how these interactions change over time. The CLIVAR research focus on tropical basin interactions has initiated a wealth of research to better understand such issues on interannual timescales. Now there is a need to extend this to more global scales. This session welcomes studies addressing teleconnections on all timescales and involving all ocean basins. This includes work based on observations, modelling studies, theory, and paleo proxies.
