Session 3: Ocean Physical Processes, air-sea interactions, and their parameterization (Chair: H. Drange, U. Bergen, Norway)
The shift to higher resolution means that some processes previously parameterized or neglected become explicitly represented, while at the same time there are different requirements for subgrid scale closures. This session will address the challenges and opportunities for improving the representation of physical processes in high-resolution models, and possibly using high-resolution simulation results to improve parameterizations used in coarser models.

Session 4: Technical Challenges (Chair: C. Böning, GEOMAR, Germany)
While many groups are using the same codes for eddy-parameterized and eddy-resolved modeling, a number of groups are developing new modeling frameworks for multi-scale modeling. How do we parameterize, test, and verify ocean models with a typical resolution of, say, 0.2° to 0.5°?. What are the lessons learned so far and remaining challenges? The volume of output from high-resolution models can be overwhelming. How can we address the data-glut?

Session 7: Meeting Conclusion and Discussion: Proposals for a new coordinated experiment design (Chair: F. Bryan, NCAR,USA)
This session will be structured around topics, including the ones emerging from session 2 presentations. Some thoughts include the following:
There has thus far been little coordination of experimental design for high-resolution modeling compared to the relatively well-established protocols for CMIP and CORE experiments. Are there common points of reference that can be exploited to help advance the state-of-the-art and facilitate sharing among groups? How best could we share high-resolution simulation data and perform coordinated analysis? Specific scientific questions that only ongoing/planned high-resolution ocean climate simulations can address.
