  1. Welcome to the 2003 PanAm PI Workshop David Gutzler US CLIVAR PanAm panel co-chair special thanks to: our hosts at NCAR David Legler, US CLIVAR Office Jill Reisdorf, UCAR JOSS

  2. Workshop goals • Bring extended PanAm research community together to exchange ideas and results • Review progress since previous PanAm PI meetings (October 1998, September 2000) • Gain community feedback about future priorities • How best to capitalize on results from existing PanAm process studies? What’s next? • Integration of process studies/modeling/analysis/ enhanced long-term monitoring • NOAA developments: PACS/GAPP merger, ISIP

  3. PanAm Science & Implementation PlanMay 2002 An outgrowth of the NOAA Pan American Climate Studies (PACS) program, building on the International TOGA program Principal US funding contributions from NOAA, NSF Elements include: • Process studies (EPIC, MESA, NAME) • Continental emphasis on warm season precipitation and monsoon circulations • Enhanced monitoring over land & ocean with a special tip of the hat to Steve Esbensen, founding panel chair

  4. US CLIVAR Pan American ResearchThree Specific Objectives • Promote a better understanding of, and more realistic simulation of, coupled ocean-atmosphere-land processes, emphasizing: a) Atmospheric response to potentially predictable boundary conditions b) Mechanisms that couple climate variability over ocean and land c) The seasonal cycles of ocean, land and atmosphere d) Effects of land surface processes and orography on the variability of seasonal rainfall patterns • Determine the predictability of warm season precipitation anomalies over the Americas on seasonal and longer time scales. • Advance the development of the climate observing and prediction system for seasonal and longer time scales.

  5. PanAm Science & Implementation PlanProcess Studies Timeline, as of early 2003

  6. US CLIVAR PanAmerican Implementation Panel panel: dinner tonight, lunch tomorrow

  7. US CLIVAR Organization CLIVAR focuses on the variability and predictability of the slowly varying components of the climate system (seasonal, interannual, decadal and centennial time scales) http://www.usclivar.org • Scientific Steering Committee (Bob Weller, Co-chair) • US CLIVAR Project Office (David Legler, Director) • Pacific, Atlantic, and PanAmerican Implementation Panels • Working groups representing other research subcommunities

  8. Intl. CLIVAR VAMOS Panel‘Variability of the American Monsoon Systems’ http://www.clivar.org/organization/vamos/index.htm

  9. GAPPGEWEX Americas Prediction Project Mission:To demonstrate skill in predicting changes in water resources on time scales up to seasonal and annual, as an integral part of the climate system. Emphases on land surface predictability, orographic precipitation, and applications of climate research to water resources management. Principal Contributions from NOAA, NASA Within NOAA: • PACS/GAPP jointly support a Warm Season Precip Initiative. • PACS and GAPP are now merging into a single program. • Merged program is central to the new NOAA ISIP Initiative.

  10. PanAm Process Studies Timeline v. 2.2(June 2003) • The PanAm panel seeks community input to extend this timeline to 2006 and beyond, striving to optimize our contribution to US CLIVAR science goals, driven by: Prioritized research needs and opportunities The national and international programmatic context US funding agency strategic plans

  11. Workshop goals • Bring extended PanAm research community together to exchange ideas and results • Review progress since previous PanAm PI meetings (October 1998, September 2000) • Gain community feedback about future priorities • How best to capitalize on results from existing PanAm process studies? What’s next? • Integration of process studies/modeling/analysis/ enhanced long-term monitoring • NOAA developments: PACS/GAPP merger, ISIP

  12. Evolution of the NAMS and its variability Response of warm season climate over North America to potentially predictable boundary conditions S-I feedbacks between land surface processes and precipitation diurnal cycle and its relationship to seasonally varying climate intraseasonal variability Better understanding of the American monsoon systems and their variability Better understanding of the role of those systems in the global water cycle Improved observational datasets Improved simulation and monthly-seasonal prediction of the monsoon and regional water resources US CLIVAR Pan American ResearchNAME ObjectivesMESA Objectives Better understanding and more realistic simulation of: Is each field study on track toward achieving its objectives? Can linkages between them be strengthened? How? Strengthen ties to EPIC? Other monsoon systems? How?
