6. 2005 SAC Meeting SAC recommendations: –Plan strategically to focus and prioritize activities leading up to next five-year proposal –Address emerging issues in predictability and the interface with climate change COLA conducted several strategic planning sessions in 2006 –Establish vision, mission, and core values –Identify assets, core competencies and opportunities –Plan themes and outline for 2009-2013 omnibus proposal

7. Vision, Mission, Core Values Vision Global society benefits from use-inspired basic research on climate variability predictability and change and the free access to data and tools to perform that research Mission Establish and quantify the predictability of seasonal to decadal variations of the Earth’s climate, including the effects of global change Core values People and teamwork Scientific and technical excellence Scientific integrity (through peer-reviewed publication) Innovative experimentation

8. Basic vs. Applied Research Pure basic research (e.g. Bohr) Research is inspired by: Quest for fundamental understanding? Considerations of use? YES NO YESNO Use-inspired basic research (e.g. Pasteur) Pure applied research (e.g. Edison) Pasteur’s Quadrant, Donald E. Stokes, 1997

9. Assets, Core Competencies, and Opportunities Assets Excellent team of scientists High-quality in-house and remote computing resources and data sets Long experience in climate dynamics modeling and analysis Core competencies Evaluation of and experimentation with Nation’s climate models Scientific leadership in seasonal-to-interannual predictability PhD education in Climate Dynamics at GMU GrADS and GDS: Highly valued, widely used information technology Opportunities The world has accepted global climate change; however, society needs to progress from global mean, time-mean, century-end projections to regional- scale, time-varying next-decade predictions Tools: new National models (CCSM-3+, CFS-2, GEOS-5) Contributing to new WCRP strategy for next 10+ years (COPES)

10. Climate of the Next Decade IPCC assessment reports provide strong evidence that global climate is changing human activity is part of the cause However, society needs information of a different sort: Climate of the next decade (or two) to match the planning horizon end-of-century results can’t answer risk assessment or mitigation questions Regionally-specific climate information global mean values can’t answer national or state planning questions Changes in weather, intraseasonal, seasonal, and interannual climate Modes of variability Droughts, floods, extremes at various time scales Society needs predictions of the total climate system from days to decades, at regional scales, with estimates of probabilities and uncertainties Different requirements for developed (U.S.) and developing countries Mission statement for all US climate research -- how will COLA contribute?

11. Requirements for Days to Decades Prediction Identify and quantify what is predictable at decadal lead times: decadal modes, role of noise, multi-scale interaction, preferred geographic regions or seasons etc. Assemble a probabilistic prediction system Develop initialization techniques and initial conditions for decadal prediction Generate retrospective research-quality climate data sets and decadal predictions Address issue of process-resolving models Determine if predicting these elements could provide societally-relevant information with 10-20 year lead times to address long-term planning & risk-management issues

12. Requirements for Days to Decades Prediction Climate components predictable at decadal leads Climate information ??? societally-relevant a decade in advance Lorenz once said that there are three questions about predictability: What do we want to predict? What can we predict? Is there anything in common between the two? It may happen that what we want to predict is hardest to predict (e.g. regional water cycle)!

13. Steps Toward Days to Decades Prediction For each time scale of interest: –Identify the climate phenomena that occur –Identify the places and times of the year where these phenomena occur –Identify the physical process(es) involved –Identify the likely origin of predictability For example …

14. Steps Toward Days to Decades Prediction

15. ~1975 9 levels 1 member ~2005 26 levels 10 members cloud(?) resolving cloud resolving needed to get ETC fluxes right (Jung, 2006) Requirement for Regional-Scale Prediction: Process-Resolving Models Resolving Cloud Processes Requires Million-Fold Increase in Computing Resources

16. COLA Omnibus, 2009-2013: Predictability of the Physical Climate System: Scientific Foundations for Dynamical Prediction from Days to Decades

17. Scientific Questions What limits predictability at all time scales from days to decades? Is there a fundamental limit? What is the role of model error? Initial conditions error? It took 30 years to determine the fundamental growth rate of NWP error -- Can we accelerate progress toward quantifying the fundamental limit of climate predictability? What aspects of the total climate system (global troposphere, stratosphere, world oceans, sea ice, land surface state, vegetation, snow) are predictable in which geographic regions, for which seasons, and how does that change in the future? For the current generation of climate models and observing systems? Future generations? Seamless prediction: Does scale interaction enhance predictability? For example, does improved prediction of intraseasonal variations improve seasonal forecasts? What is the optimal combination of models to predict means? Extremes? Current models have huge limitations, e.g. for regional water cycle  need to develop a multi- model ensemble combination that produces the best forecast Predictability of the Physical Climate System

18. Multi-Model National Models Framework CFS (NOAA) Bridges the gap between NWP and S-I prediction Routinely evaluated in real-time seasonal prediction mode Collaboration with NCEP (+ Climate Test Bed) CCSM (NSF) Bridges the gap between S-I predictability studies and global climate change studies (e.g. COLA S-I predictions w/ CCSM-3) Collaboration with NCAR (model development) GEOS (NASA) Bridges the gap between coupled modeling and assimilating space-based observations (atmosphere and ocean) Collaboration with GMAO (+ MAP program) GFDL (NOAA) ???
