5 Components in blue communicate trough a coupling component. Components in red are subroutines of blue components. CLM CAM CICE HAMOCC MICOM Atmospheric chemistry River routing NorESM framework and model components Development and drift of Earth system modelling 600+ model years of pre-industrial spinup completed. The integration is being analysed for model quality and drift Production runs started early Feb 2011 The production period will last 3-4 months model years will be produced Total storage requirement is estimated to 150TB

6 External forcing and Atlantic variability Otterå et al. (2010), Nature Geoscience A recent study indicate that volcanic eruptions can have a proufound impact on climate not only short term climate variability, but also for variability on longer time scales

7 Forstå dekadavariasjoner fra modeller og paleo-data Simulated NAO (500 hPa) vs Ormen reconstruction Remarkable similarities between model and data on multidecadal time scales => link to gyre circulation? Atlantic ocean core locations Otterå, Dokken et al., in prog.

8 Ocean acidification in Arktis Using a coupling between observations and modelling The first to show the exceptional sensitivity of the Arctic to ocean acidification pH reduction Bellerby et al., 2005; 2010

9 Process studies of ecosystem response Climate change response to and enhanced biological carbon pump in a high CO 2 ocean? Bellerby R. G. J., Schulz K. G., Riebesell U., Neill C., Nondal G., Heegaard E., Johannessen T., and Brown K. R., Biogeosciences, 5, Riebesell U., Schulz K. G., Bellerby R.G.J., Botros M., Fritsche P., Meyerhöfer M. Neill C., Nondal G., Oschlies A. and Wohlers J Nature 2007;450:

10 Monetoring ocean CO 2 uptake Watson et al., Science, 2009 Measurements from Voluntary Observing Ships Showed large interannual variability of the North Atlantic carbon dioxide sink

11 Regional downscaling European domain – Heikkilä et al. (2010) Tropical channel domain – simulation example prepared by Lunde and Mesquita
