  1. Progress of US CLIVAR during 1998-2013 • Reasons for recapping progress: • - Present advances in scientific understanding of the climate system • Demonstrate the return on investment of agency funding and interagency coordination of US CLIVAR research • US CLIVAR has had two phases • - Phase 1, 2000 through 2005—Aligned with International Science Plan • - Phase 2, since 2005 Reorganization—Leverages intl efforts and provides information to be more useful domestically • How do we best present progress? • - By science question? • - By program goal? • - By phenomena or research topic? • - By our panel foci? • Should set stage for science questions and goals of future program

  2. By Program Goals • Identify and understand the major patterns of climate variability on seasonal, decadal and longer time scales and evaluate their predictability • Expand our capacity in short term (seasonal-to-interannual) climate prediction and search for ways to predict decadal variability • Better document rapid climate changes and the mechanisms for these events, and evaluate the potential for abrupt climate changes in the future • Evaluate and improve the models used to project climate change due to human activity, including anthropogenically induced changes in atmospheric composition • Detect and describe any climate changes that may occur • “U.S. CLIVAR has identified improved predictive capability as the main objective to leave as its legacy. "

  3. By Phenomena • Modes of Variability • El Nino-Southern Oscillation • Tropical Atlantic Variability • Madden Julian Oscillation • Arctic Oscillation/North Atlantic Oscillation • Pacific Decadal Variability • Atlantic MultidecadalVariabilty • Antarctic Oscillation • Ocean Variability and Predictability • Atlantic Meridional Overturning Circulation • North Pacific Gyre Oscillation • Western Boundary Currents • Southern Ocean/Antarctic Circumpolar Current • Salinity Variability

  4. By Phenomena • Monsoon Systems • American Monsoon • African Monsoon • Asian-Australian Monsoon • Climate Extremes • Drought • Hurricanes • Temperature and Precipitation Extremes • Anthropogenic Climate Change • Response of Modes/Patterns • Response of Extremes • Abrupt Changes • Sea Level Rise

  5. By Activity • Building and Bolstering the Climate Observing and Data Systems • In-Situ • Tropical Moored Arrays, Surface Drifters,Repeat Hydrography, VOS/XBT, ARGO Array, Ocean Reference Sites, AMOC Observing System, Surface Met and Upper Air Network… • Remote Sensing • GOES/NPOESS, SST, Precipitation, Clouds, GPS/Integrated Water • Vapor, Altimetry,Scatterometry, Ocean Color, Salinity,,, • Climate Model Development and Improvement • Process Studies • Climate Process Teams • Analyses and Reanalyses • Assimilated Ocean and Atmospheric Data Sets and Reanalyses, Coupled Reanalyses • Prediction and Projection Improvement • Applications Interface
