Title: Global ocean-atmosphere climate teleconnections

Abstract: Interannual to multi-decadal climate variability across the global ocean-atmosphere system shows evidence of being interconnected across ocean basins and across hemispheres. In this talk I will outline how global ocean-atmosphere climate teleconnections link the tropics to high-latitudes, and the Southern Ocean to the North Atlantic. Each of the tropical Pacific, Atlantic and Indian Oceans interacts with adjacent ocean basins as well as teleconnecting to polar latitudes. Via propagating planetary waves in the ocean, the Southern Hemisphere can trigger changes in the North Atlantic on multi-year time-scales, and in turn, the North Atlantic overturning circulation can alter the location of the ITCZ, the strength of the Walker Circulation, and the atmospheric circulation in the Amundsen Sea.
