PC21A:
Midlatitude Climate Dynamics and the Role of the Ocean I


Session ID#: 9329

Session Description:
Climate dynamics is fundamental to understand and predict regional to global climate variability and change. More information on this topic is rapidly becoming available due to increasing amount of data from both models and observations, particularly at high resolution. International climate research programmes such as CLIVAR recognize the importance of climate dynamics. This session explores climate dynamics in mid-latitudes and the role played by the ocean. Four major topics of this session are: 1) storm tracks, jet streams and weather systems, 2) air-sea interactions, in particular ocean-to-atmosphere influences, including those over oceanic currents and fronts, 3) climate phenomena such as the North Atlantic Oscillation, Pacific Decadal Variability, teleconnections and their relevance for regional climate variability and change and 4) processes, variability and change in the ocean and coupling with other components of the climate system, such as the cryosphere and stratosphere. Theoretical, numerical and observational studies are welcomed.
