1 The EUROBRISA Project David Stephenson University of Exeter 2 nd EUROBRISA workshop, Dartmoor, UK, July 2009

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!

4 Partner committments University of Exeter, School of Engineering, Computer Science and Mathematics (UK): Overall coordination of the network assisted by the Network Facilitator Expert advice in the statistical calibration, combination, and verification of forecasts Centre for Weather Prediction and Climate Studies (CPTEC, Brazil): Develop and implement a procedure for producing best quality seasonal climate forecasts Act as the S. 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 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); –Data needs and development of system; –Joint publications

6 EUROBRISA plans Improving the EUROBRISA system –Inclusion of more forecast models: CPTEC, MF, GLOSEA4 –Improved skill: wider domain, streamfunction, more robust calibration –New visualisation e.g. the ternary colour scheme –Monthly mean precipitation output? (for use in applications) Integrated applications –Common EUROBRISA calibrated forecast data –Time period – recent La Nina (July Jan 2010) –Case study common regions? NE Brazil, SE Brazil, ?? Research outputs/publications –Overview of system + apps (Bulletin AMS) –Calibration paper(s) –Applications papers –New visualisation of forecasts paper(s) 3 rd year workshop in Brazil in 2010 Any other matters? Please keep questions/comments short, focussed, relevant to EUROBRISA!
