  2. MONSOON EXPERIMENT IN SOUTH AMERICA (MESA) An internationally coordinated, joint CLIVAR – GEWEX program aimed at providing: a better understanding of the South American monsoon system and its variability, a better understanding of the role of that system in the global water cycle improved observational data sets, and improved simulation and prediction of the monsoon and regional water resources. Carolina Vera Univ. of Buenos Aires MESA SWG Chair

  3. MONSOON EXPERIMENT SOUTH AMERICA (MESA) HYPOTHESIS: The SAMS provides a physical basis for determining the degree of predictability on short- and long timescales over the region. • MESA PRIORITY RESEARCH • AREAS (PRA): • Better understanding and • simulation of: • diurnal and mesoscale processes • (PRA-I); • intraseasonal variability • (PRA-II) • response to oceanic and • continental boundary • conditions (PRA-III); • monsoon evolution and • variability (PRAs-I, II, III).

  4. MESA main scientific areas • Diurnal cycle of precipitation, including interaction with soil hydrology . • Issues related to diagnoses and simulations of the ISO, the SACZ, and the onset and decay of the SA monsoon system (SAMS) from the intra-seasonal to the decadal time scales. Impact of anthropogenic climate change on the SAMS • Role of land surface and air-sea interaction in inter-annual variability? Coupled (ocean-atmosphere) processes in the maintenance and variability of the SACZ • Extreme events. Impacts of global climate change and land use change on regional weather, climate, hydrology and agriculture.

  6. MESA & other Programs VAMOS/MESA contributed to the design of the GCOS Action Plan for South America. The Plan was presented at the COP10. Enhancement of the upper-air network Enhancement of Sustained Observations in the WS Atlantic

  7. MESA Support MESA has a strong international participation from Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, Uruguay and USA (~70 principal scientists) Funding for MESA activities provided by: • NOAA/CPPA Program • NSF • National Funding Agencies of South America (Argentina, Brazil, Chile, Paraguay, Peru, Uruguay, ~$500-700K/y) • European Commission (CLARIS, $200/y) • IAI (PROSUR, $200K/y) • GEF (La Plata Basin, $3M/y, requested for observing system enhancement )

  8. MESA Research Implementation plans and prospectus: • American Low Level jetS: A Scientific Prospectus and Implementation Plan. • Climatology and Hydrology of the Plata Basin: A Document of VAMOS Scientific Study Group on the Plata Basin. • MESA Implementation Plan (in preparation) MESA Publications (2002-2005): • METEOROLOGICA special issue on South American Monsoon System (2002) • CLIVAR Exchanges special issue on SALLJEX (2004) • SALLJEX Overview Paper (BAMS, 2005) • Review of the American Monsoon Systems (J. Climate, special issue for CLIVAR Science Conference, 2005) • These last two publications list relevant MESA papers published in refereed journals.

  9. MESA MILESTONES • FY04: • Quantitative information of the model errors in SALLJEX • Evaluation of impact of SALLJEX data on analysis and forecasts • Confirmation about the ability of the models to reproduce some of the elements of the low-level circulation of the SAMS • Preparation of GEF-PLATIN survey reports • FY05: • SALLJEX Data Assimilation. • Planning of LPB CSE monitoring activities. • Assessment of the IPCC-AR4 simulations in the SAM region. • FY06: • Assessment of Seasonal prediction simulations in the SAMS region. • Development of MESA climate indexes • Seasonal simulation of SALLJEX season. • LPB CSE monitoring implementation. • Predictability of the SAM associated with Atlantic SST simulations. • Regional downscaling of IPCC-AR4 simulations. • FY07: • LPB CSE experiment implementation, data collection, and integration. • Assessment of extreme event frequency changes in the regional climate change scenarios for South America and their impact on agricultural activities. • FY08: • Evaluate the impact of soil moisture in simulations and predictions. • Hydrological studies of PLATEX data • …Ultimate goal: Integrated view of the American Monsoon Systems, related interhemispheric connection, monsoon predictability and prediction
