  1. METGRID 2005. 1. 27 KMA Supercomputer Center Dongil LEE

  2. Background of METGRID • Why weather agencies are using Supercomputer? • Current and future weather forecasting -> Numerical Weather Prediction • Two ways of best efforts • Improving the initial field of NWP (best analysis, data assimilation…) • Decreasing the uncertainty of NWP product (ensemble weather forecasting, super -, Multi-model ensemble with different initial field

  3. Limitation of Single Centerfor weather forecasting • Human resources • Data resources • Computing resources

  4. Some basis/related issues • THOPEX • WMO FWIS • GEOSS • Gloriad • Grid • E-Science Single Global Weather Forecasting

  5. METGRID starting • Dr. David Roger (Chief Executive, Met Office, UK) outlined a possible future scenario for global weather forecasting – August 2004 • Prof. Geerd-R Hoffmann (DWD), Vice president of CBS, WMO prepared ‘proposal for a technical feasibility study’ - November 2004 • 7 centers will have first coordination meeting of METGRID – March 2005

  6. Purpose of METGRID • All major global weather forecasting centers of the world • To share their global forecasts with each other as a multi-model ensemble • To agree on areas of the world which merited further studies • To carry-out detailed ensemble predictions for these regions • Studies are undertaken as part of the THOPEX research program

  7. Partners of METGRID

  8. Issues of METGRID • Organizational issues • Communication • Software • Operational aspects • Pilot phase and other aspects

  9. Action needed • Agree on first outline of proposal in principle • Agree on proposal for study • Set up a project for carrying out the study and agree on resources • Deliver results of study ( ~ 09/2005 ) • Start of pilot phase ( 01/2006 ~ )

  10. KMA status • Partnership with DWD for V-GISC • Simple UNICORE test with DWD • Setting up UNICORE including user interface for 2nd Supercomputer System • Intent to expand Partnership with CAgM of WMO, NCAR, Grid Community and others…

  11. Thank you
