6. The purpose of this meeting was to follow up on the recommendations of the World Modelling Summit, and actions resulting from the JSC meeting in Antalya, Turkey, on the subject of modelling. The JSC discussed at length the formation of a WCRP Modelling Council in the context of WCRP visioning and future direction to carry out the following functions: – Promoting greater use of observations and results of process studies in/with models; – Promoting collaboration amongst various climate science communities (includes numerical weather prediction (NWP), seasonal to interannual prediction, and climate projection as well as those dealing with biogeochemistry, air quality, terrestrial ecology, etc.); – Promoting application of models to problems of societal relevance, quantifying uncertainties and making sure they are well communicated and understood; – Promoting the model development and improvements. Modeling Coordination Meeting

7. Research Contributions to Climate Services Task Team: Chair Greg Flato Coming out of last year's JSC meeting, one of the action items was to develop the WCRP position on research in support of climate services. Charge: to form a sub-set of the JSC and some of the Project co-chairs to follow up on discussions/deliberations at the JSC, our latest input to the GFCS High Level Task Team, and to develop further the role of WCRP Research in Climate Services. Topics for consideration: What are the envisioned contributions of WCRP to the Framework for Climate Services? What are the potential strategies/approaches for development and sharing of the climate knowledge and resulting from WCRP and its affiliate Projects with potential partners? Who are the potential partners external to WCRP? What role WCRP can and should play in facilitating and promoting best practices in development and dissemination of reliable climate information? (Implicit in this request is consideration of what we should not be doing?.) How should WCRP best organize itself in this regard?

8. WCRP Data Council Transition Plan from WOAP to a Data Council Sarah Gille, Chair from JSC Mike Manton, WOAP ChairMike Bosilovich, Re-analysis Adrian Simmons, GCOSToshio Koike WCRP Info System Karl Taylor, CLIVARChris Kummerow, GEWEX Colin Jones or CORDEX rep.Veronika Eyring, Modeling Council Meeting Jeff Key, CliCMichaela Haegglin, SPARC Norm McFarlane, Executive Sec. Charge: Identify WCRP functions in coordinating research on observations and new observations required for climate research, especially for process understanding and model development and evaluation. Identify WCRP functions in coordinating the development, stewardship and dissemination of climate information resulting from its research, modeling and analysis activities. Develop a framework for coordination an integration of pan-WCRP observations, analysis and information management activities identified above; Recommend how the proposed framework should be organized and supported within WCRP in a manner that is complimentary and value added to the activities of Projects and sister programmes (e.g. GCOS, CEOS, GEOSS, WIS, etc.).

9. WCRP JSC 32, Met Office, Exeter, UK 4-8 4-8 April 2011 Agenda & Expectations and Outcomes Discuss the transition/evolution of the WCRP and its core projects Discuss the WCRP Open Science Conference agenda and its outcome for developing the future functions and structure of the Programme and Projects

20. WCRP Workshop on Polar Predictability on Seasonal to Multi-Decadal Timescales Bergen, Norway, 25-29 October 2010, ~80 participants Focus on scientific challenges, rather than programmatic Despite limited investment and emphasis in the past, early results concerning the extent of polar predictability show promise. We understand many of the physical sources of predictability in the polar climate system, but there is lack of a good understanding of many of the feedback mechanisms between the different components of the climate system, and the physical causality of the large-scale modes of variability in the polar regions. Coordination & Partnerships

21. Several areas of potential collaboration: CHFP protocol encourages interactive ice models: additional experiments with diagnostics for cryosphere Sea ice prediction and initialization Experimental Protocol Developed and Numerical Experiments Underway Spring snow melt into soil moisture and influence on spring temperature anomalies Explore seasonal predictability associated with snow and sea ice

22. Examples of possible research foci: – Seasonal predictability and seasonality of long-term changes – Forced and unforced components of decadal predictability – Initial state estimates – Extent of potential predictability The first action would be to hold a focused meeting, to develop a detailed implementation plan (beginning of 2012). Cooperation with partners, e.g. with Thorpex (and Polar Thorpex) essential, Chair invited, joint work foreseen. This could be a contribution to the WMO Global Integrated Polar Prediction System (GIPPS), and an element of the potential International Polar Decade initiative.
