1. 1 The EUROBRISA Project David Stephenson University of Exeter 1 st EUROBRISA workshop, Paraty, Brazil 16-18 March 2008

2. 2 Aims of EUROBRISA 1.Strengthen collaboration and promote exchange of expertise and information between European and South American climate scientists; 2.Produce improved seasonal climate forecasts for South America using recent scientific advances in both coupled ocean-atmosphere modelling and statistical calibration and combination of multi-model ensemble forecasts; 3.Develop forecast products for non-profitable governmental use in South America (e.g. reservoir management, hydropower production, and agriculture). A GREAT OPPORTUNITY TO DO SOMETHING REALLY IMPRESSIVE!

American point of contact for the Network. European Centre for Medium-Range Weather Forecasts (ECMWF): Provide CPTEC with real-time seasonal forecast data from the European coupled model forecasting systems Met Office (U.K. Met Office): Provide ECMWF with real-time seasonal forecast data from the U.K. Met Office forecasting system; Advise on the development of forecast products for applications in S. American hydropower production; Collaborate with the U. of Exeter on how best to improve the seasonal forecasting system. Météo-France: Provide ECMWF with real-time seasonal forecast data from the Météo-France coupled model forecasting system Federal University of Paraná (UFPR - Brazil): Develop a seasonal stream flow forecasting system for use in hydro-electric power production forecasting Perform diagnostic studies of hydrologic extreme events Brazilian National Institute of Meteorology (INMET): Research on the use and value of the combined and calibrated forecasts in agricultural activities University of São Paulo, Department of Atmospheric Science (USP, Brazil): Theoretical and observational studies of seasonal predictability Production of regional seasonal predictions for southeast Brazil

5. 5 Objectives of this workshop Give EUROBRISA partners chance to meet each other and share ideas; Report on research achievements; Plan what to do next: –Identify research required for improving South American seasonal forecasts; –Identify research required for user applications (e.g. agriculture, hydropower and health); –Any other good ideas??!

6. 6 EUROBRISA achievements so far 1.Strengthen collaboration between European and S. American climate scientists 1 st EUROBRISA workshop (Mar 2008) EUROBRISA web site launched (Oct 2007) www6.cptec.inpe.br/eurobrisa Network facilitator appointed in Exeter (Oct 2007) 2. Produce improved seasonal climate forecasts for South America Creation of a great case study event – La Nina 2008! New visualisation approaches for seasonal forecasts Project summary published in CLIVAR Exchanges (Oct 2007) Real time forecasts and verification products made available online (Oct 2007) Real time forecasting system set up in Brazil (Jul-Oct 2007) 3. Develop forecast products for non-profitable governmental use in South America Entrainment of new application areas (e.g. health)
