The main project goal is to provide a comprehensive understanding of the role of synoptic and mesoscale eddies in the large-scale oceanic circulation at the global and regional scales and in the climate variability. To achieve this goal, we propose to adopt and use the best available ocean eddy-resolving general circulation models (GCMs) in global and regional configurations. In this framework specific scientific objectives and technological challenges are to be met.


  • To analyze the mechanisms through which ocean synoptic and mesoscale eddies steer ocean intrinsic variability (i.e., driven not by the external forcing but by the internal dynamics) and to quantify the role of this variability in forming long-term changes in the ocean state and basin-scale circulation modes.
  • To quantify the role of ocean synoptic and mesoscale eddies and associated ocean intrinsic variability modes in global and regional climate variability and change and to provide improved climate projections accounting for the ocean-related natural variability impact on global changes.
  • To quantify signatures in air-sea energy fluxes associated with ocean and atmosphere synoptic and mesoscale variability. For that purpose we propose to examine the coupling between oceanic mesoscale and atmospheric synoptic variability in the Atlantic Ocean by analyzing two major effects (i) eddy modulation of the air-sea heat fluxes; (ii) effects of atmospheric synoptic and mesoscale variability (“weather”) on oceanic eddies.
  • To analyze the mechanisms of generation and to quantify the role of the mesoscale and submesoscale eddies in the semi-enclosed seas (e.g. in the Black, Barents and Okhotsk seas) in transporting heat, momentum, buoyancy, and potentially terrigenic substances and ion forming regional climate anomalies and extremes.
