GEF-Supported Project for the La Plata Basin
Requesting Agency: United Nations Environment Program (UNEP)Local Exec Agency: Intergovernmental Coordinating Committee forLa Plata Basin (CIC), in co-operation with water agencies of Argentina, Bolivia, Brazil, Paraguay, and Uruguay, and VAMOS/PLATINCurrent Status: The project was presented to GEF for final approval (tentatively by July 2006)Project Total Cost: GEF has placed $15M on Reserve; Countries andOther Sources may contribute 2:1 for a potential total of US $45M.
The LPB (former PLATIN) group had the responsibility of planning the Program component related with the prediction of hydrological impacts due climate variability and change. The plan includes (including development of climate and hydrologic scenarios for the Basin in the context of climate change, coordination, integration, and improvement of the operative systems for atmospheric and hydrological prediction (observing system improvement, conventional and remote sensing data assimilation, model transferability, etc.)
The participation of the CLIVAR-GEWEX Group in the GEF Program is unquestionably a great example of how WCRP science can be applied to solve societal needs, while at the same time it provides additional funding for climate monitoring, field campaigns, as well as regional database enhancement.

MODELING GROUP for VAMOS (MGV)MODELING GROUP for VAMOS (MGV)
OBJECTIVESOBJECTIVES• Develop VAMOS (Integrated) Modeling Implementation
Plan:– Assessment of Models (Integration NAME-MESA-
VOCALS) • Requires Collaboration / Integration between Research and
Operational Centers– Hypothesis Driven Numerical Experimentation– “Climate Process Team” Model
Development/Improvement Strategies
• Need Integration between Field Activities, Data Assimilation, Research Modeling and Operational Forecasting
VAMOS MODELING ISSUESVAMOS MODELING ISSUES
• The MGV requests guidance on how to vet and promote the VAMOS Modeling Plan (VMP) through international CLIVAR.
• VAMOS recognizes that the VMP, with respect to forecast verification, is relying heavily on WGSIP and COPES-TFSP activities and we want to make sure these activities are supported. This is a particular concern with respect to forecast data sharing.
• Some interaction with the IPCC community is emerging; however, SSG and JSC support of interactions with WGCM would be welcomed.
• SSG and JSC review of the modeling plan is welcomed.
MODELING ISSUESMODELING ISSUES• Basic “universal” problems relevant to NAMSBasic “universal” problems relevant to NAMS
– Poor simulation of warm season continental climates– Poor simulation of diurnal cycle (related to above)– Poor predictions of warm season precipitation
• Resolution issuesResolution issues– Need to resolve key phenomena– Application specific (e.g. regional impacts, extreme events)– Computational issues: need for long runs, large ensembles
• Physics issuesPhysics issues– Limitations of convection parameterizations, but intimately
linked to surface interactions, boundary layer, clouds, etc.– Schemes largely untested at high resolution
• Prediction issuesPrediction issues– Role of SSTs (especially other than ENSO)– Role of land surface feedbacks (strength, time scales)– Role of intraseasonal variability (e.g. MJO)– Seasonal differences in predictability– Current Level of Skill
