Objective

The atmospheric North Atlantic Oscillation (NAO) is the most important mode of northern hemisphere climate variability, and has major impacts over Europe. This project will investigate the response of the ocean circulation ta NAO-related atmospheric forcing , and assess the potential predictability of the NAO. Existing integrations of a high resolution primitive equation model of the Atlantic ocean circulation will be diagnosed to trace the influence of the atmospheric NAO from the surface forcing through to the general circulation. Processes such as the establishment of SST anomalies, their subduction and advection, and the creation of deep water masses and modification of the meridional overturning circulation will be traced back to the NAO through individual process studies and through statistical analysis of correlated time series of selected oceanic indices. The subsequent impact on the atmospheric circulation will be addressed with coupled model simulations using the same ocean model . Long integrations and "perfect model" ensemble experiments will be used to asses objectively the potential for predicitng the NAO on timescales from seasons to decades . Atmospheric processes will be diagnosed using a simplified primitive equation model. Research findings will be disseminated through scientific articles in international journals, popular articles for the general reader and a web page with popular explanations and downloadable data.
