Presentation Transcript

  • 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


  • 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. "


  • Modes of Variability

    • El Nino-Southern Oscillation

    • Tropical Atlantic Variability

    • Madden Julian Oscillation

    • Arctic Oscillation/North Atlantic Oscillation

    • Pacific Decadal Variability
