The Science of PPAI

Current PPAI Activities

PPAI GOALS

  1. Further fundamental understanding of climate predictability at seasonal to centennial time scales
    • Develop and promote standard metrics and practices for evaluating predictability and prediction
    • Encourage coordinated U.S. participation in emerging international multi-model predictiona nd attribution activities
    • Quantify prediction uncertainty and its sources
    • Assess predictability of key climate forcings
  2. Improve provision of climate forecast information, particularly with respect to drought and other extreme events
    • Assess baseline predictability of drought on weeks to decades.
    • Coordinate and “advertise” scientific support for multi-agency research efforts that address local and remote sea-air-land mechanisms of drought and its predictability, at interannual to decadal timescales (joint with GEWEX)
    • Assess possible future changes in drought
    • Identify/collect/document monsoon indices to observe and predict (help from POSP)
    • Assess baseline simulation capability of complete annual cycle of global monsoon and its variability, including diurnal component (help from PSMIP)
    • Assess baseline predictability of identified monsoon indices
    • Quantify relative roles of ocean/atmosphere and land/atmosphere processes (with POSP & PSMIP)
    • Assess potential future changes of global monsoons
  3. Foster research and development of prediction systems for climate impacts on ecosystems
    • Improve understanding of oceanic and atmospheric patterns, and consequent forcing mechanisms, that organize ecosystems and determine the spatial and temporal distribution of water resources. (with PSMIP)
    • Quantify the predictability of key oceanic and atmospheric processes that influence ecosystems and water resources.
    • Develop tools for transforming climate forecasts into ecosystem and water resource forecasts at lead times from sub-seasonal to centennial and at appropriate spatial scales
    • Develop ability to quantify relative contributions of anthropogenic climate change and natural climate variability to observed long-term changes in ecosystems and water resources
  4. Enable use of CLIVAR science for improved decision support
    • Develop integrated linkages to interdisciplinary programs: NOAA RISA and OGP, IRI, IPCC, CCSP, NASA efforts, NSF NEON / CUAHSI / CLEANR / ORION, Ocean Observing Systems, public entities such as WGA / NGA.
    • Promote/support projects that link climate observations, forecasts, and scenarios with resource assessments and forecasts
    • Promote sustained interactions with other disciplines and research communities to ensure delivery of “usable science”
    • Emphasize spatial and temporal scales of information needed for applications. Contribute support for the development, use, interpretation, and evaluation of tools (e.g. downscaling) employed by applications.
