RESEARCH INTERESTS  

My main interest is in analysis and inter-comparison of climate models, with attention on ocean circulation, air-sea interaction, and sea ice in the North Atlantic Ocean and the Nordic Seas on interannual-to-decadal time scales. More specifically, my research focus on the understanding of Subpolar Gyre dynamics, Atlantic Meridional Overturning Circulation, and water mass structure and transformation in climate models. I am particularly interested in those mechanisms that give rise to predictability on interannual-to-decadal time scales in the North Atlantic and the Nordic Seas. 

  • Decadal variability and predictability of ocean surface variables in the North Atlantic sector

  • Ocean circulation in the subpolar North Atlantic and Arctic Mediterranean (Subpolar Gyre and Thermohaline circulation)
