Pre-Meeting Reports


Agenda (13 September 2010)

The meeting on Thursday afternoon will be located at the Center Green Auditorium, while on Friday and Saturday, the meeting will continue at the NCAR Mesa Lab. A shuttle bus service will take participants to the venues from the Boulder Marriott and Millennium hotels.

Thursday 23 September

CLIVAR SSG-17 Action Items And Membership Issues - G. Danabasoglu
CLIVAR SSG, Imperatives and WCRP Modeling - A. Pirani
WCRP Modeling Coordination Meeting, Paris 15-17 Nov 2010 - G. Danabasoglu

CORE presentations and discussions

CORE IAF Dataset Update and CORE-II NCAR Simulations - G. Danabasoglu
Summary Of NCAR Modeling Activities - G. Danabasoglu
Update On CORE-II at GFDL - S. Griffies
Developments In The NorESM Ocean Component - M. Bentsen
ACCESS Ocean And Sea Ice Model CORE Simulations - S. Marsland
Experience with CORE II IAF In JMA/MRI - H. Tsujino
CORE-II Related Activities AT IFM-GEOMAR - C. Boening
Forcing Ocean Models With The Compo et al. (2009) 20th Century Reanalyses Project And Exploring Partial Coupling Of Ocean-Ice Models (R. Gerdes)

Mean State And Variability In A Suite Of Forced Global Ocean-Ice Simulations: The Interannual Coordinated Ocean-ice Reference Experiments (CORE-II) - Atlas/Paper Outline (S. Griffies, All)

Joint meeting with the US CLIVAR Working Group on Decadal Predictability

Summary of the DPWG charge and activities (Solomon)
Summary of CORE interannual forcing data and experiments (Danabasoglu)
Ocean model related or other relevant metric details pertaining to decadal prediction (Goddard)

Goal: explore and discuss common interests and projects, e.g., decadal variability diagnostics, including in eddy-permitting models; role of CORE II IAF experiments.

Joint meeting with the Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean (DIMES) - see here for the full DIMES meeting agenda.

Current practices in ocean diapycnal modeling (including model sensitivities) (M. Jochum)
Comparing methods for computing K (R. Ferrari)
Modeling tracer transport in the DIMES region (E. Shuckburgh)
Current practices for (sub)mesoscale mixing at NCAR (G. Danabasoglu)
Current practices for (sub)mesoscale mixing at GFDL (S. Griffies)
Diagnosing eddy diffusivities from eddy-permitting models (B. Fox-Kemper or F. Bryan)


• How can DIMES results contribute to model development?
• In what form are DIMES findings needed to help modelers?
• How can modeling efforts contribute to DIMES data analysis?
• Is DIMES a candidate for a CPT effort?
• Are existing parameterizations of isopycnal mixing pertinent?
• What happens when interior diapycnal mixing is at the noise floor of the measurement systems---can models cope with such low mixing levels?
• If diapycnal mixing varies spatially, at the moment is it more useful to work towards mapping a climatology of these variations or identifying the mechanisms that make it vary?
