  1. Pierre DANIEL Météo-France Technologies for Search, Assistance and Rescue Brest, France, 18-19-20 October 2004 The Météo-France operational SAR model

  2. Met-ocean support & drift forecastMarine pollutions, containers & SAR Permanent & Global support since 1994 (marine pollutions) and 1996 (containers & SAR) Operated by skilled forecaster on duty A trained French organisation: Préfets Maritimes / Cedre / Météo-France / CROSS The Météo-France operational SAR model

  3. MOTHY drift system  In a fighting loop Pollutant/object behaviour Dynamics Forecaster Observations Forecasts Hydrodynamic ocean model + Trajectory model Direct access to weather forecasts ; forecaster’s validation

  4. Forces on a drifting object • Wind • Surface current • Waves (not included) • A key parameter: immersion rate The Météo-France operational SAR model

  5. Containers

  6. Various objects Forecast valid for 05/02/02 The Météo-France operational SAR model

  7. Search and rescue: sailing yacht The Météo-France operational SAR model

  8. An increasing demand The Météo-France operational SAR model

  9. Search objects (2004) The Météo-France operational SAR model

  10. Who ask for? (2004) The Météo-France operational SAR model

  11. Search locations Person in water Craft Object (container) whale The Météo-France operational SAR model

  12. MODELISATION ASSIMILATION SATELLITE JASON IN SITU CORIOLIS Work in progress Improvement of the hydrodynamics: large scale currents (Mercator, FOAM, MFS). The Météo-France operational SAR model

  13. Work in progress Men in water: 12 days drift The Météo-France operational SAR model

  14. Work in progress and forecasted • Survey of the needs: a questionnaire for the CROSS • Model improvement: object shape, hydrodynamics: large scale currents (Mercator, FOAM…), waves, coastal effects • A need for reliable observations • Collaborative frameworks The Météo-France operational SAR model

  15. The end
