The North Atlantic: natural variability and global change
Convener: Monika Rhein  | Co-Conveners: Richard Greatbatch , Neil Wells 
 / Mon, 13 Apr, 08:30–12:00  / 13:30–17:00  / Room Y4
 / Attendance Tue, 14 Apr, 17:30–19:00  / Yellow Posters

The North Atlantic exhibits a high level of natural variability from interannual to centennial time scales, making it difficult to extract trends from observational time series. Climate models, however, predict major changes in this region, which in turn will influence sea level and climate, especially in western Europe and North America. One important issue is the interaction between the atmosphere and the ocean, and how this affects the climate in Europe.

We welcome contributions from observers and modelers on the following topics:
-- climate relevant processes in the North Atlantic region in the atmosphere and the ocean
-- response of the atmosphere to changes in the North Atlantic
-- atmosphere - ocean coupling in the North Atlantic realm on time scales from years to centuries
-- interpretation of observations in the atmosphere and the ocean in the North Atlantic sector
-- comparison and interpretation of changes in the North Atlantic sector and Europe (atmosphere and ocean) in climate models
-- the role of the Atlantic meridional overturning circulation
-- variability in the ocean and the atmosphere in the North Atlantic sector on a broad range of time scales
-- changes in adjacent seas related to changes in the North Atlantic
-- role of water mass transformation and circulation changes on anthropogenic carbon and other parameters
-- linkage between the observational records and proxies from the recent past
