  3. Computer resources • Cray X1e • 15 nodes, 8 MSP’s each node • 4 SSP’s each MSP • 320 Gb memory • 2.3 TF peak performance • Official acceptance: June 2005 27th EWGLAM & 12th SRNWP Meetings

  4. Cray X1e MSP 27th EWGLAM & 12th SRNWP Meetings

  5. Hirlam operational model • ONR • 0.16 deg latxlon, 40 levels • 72 hours forecast, 4 times a day • 3DVAR • BC’s from ECMWF • HNR and CNN • 0.05 deg latxlon, 40 levels • 36 hours forecast, 4 times a day • 3DVAR • BC’s from ONR 27th EWGLAM & 12th SRNWP Meetings

  6. ONR integration area 27th EWGLAM & 12th SRNWP Meetings

  7. HNR – CNN integration areas 27th EWGLAM & 12th SRNWP Meetings

  8. Verification 2005 • Standard verification against observations. • Verification against Spanish High Resolution precipitation network. • Monthly comparison ONR-HNR models for Spain. 27th EWGLAM & 12th SRNWP Meetings

  9. Geopotential June-August 2005 27th EWGLAM & 12th SRNWP Meetings

  10. MSLP June-August 27th EWGLAM & 12th SRNWP Meetings

  11. Precip. by thresholds POD-FAR 27th EWGLAM & 12th SRNWP Meetings

  12. Wave operational model • WAM 4 for Atlantic and Mediterranean • High resolution shallow water model 27th EWGLAM & 12th SRNWP Meetings

  13. Wave operational model 27th EWGLAM & 12th SRNWP Meetings

  14. High Resolution Wave operational model 27th EWGLAM & 12th SRNWP Meetings

  15. Hirlam Project – Data Assimilation • 3DVAR in operational models. • Assimilation of GPS data (TOUGH project). • Test of Hirlam 4DVAR in the Cray X1e. • Soil moisture analysis comparison between Hirlam reference system and 1DVAR version (ELDAS project). • Mesoscale Rapid Update Cycle of analysis of surface parameters. • Assimilation of VAD winds from INM radar network. 27th EWGLAM & 12th SRNWP Meetings

  16. PP thresholds (0.1, 0.3, 1., 3., 10., 30., 100. mm in 24 hours) Spring period:15 April-15 May 2004 Impact of introducing 31 new GPS sites Verification with INM Climate stations (upscaled to 22km). • ETS and TSS show that increasing the number of GPS sites improves model precipitation. 27th EWGLAM & 12th SRNWP Meetings

  17. Hirlam Project – Dynamics • Different strategies of coupling dynamics-physic in Hirlam. • Stability and same meteorological quality with larger time step. 27th EWGLAM & 12th SRNWP Meetings

  18. Hirlam Project – Physics • Surface processes: • Snow OI analysis. • ECOCLIMAP database in Hirlam. • New formulation of snow processes using two additional tiles: • snow over open land • Snow over forest 27th EWGLAM & 12th SRNWP Meetings

  19. Hirlam Project – Physics • Convection: • New moist scheme based on Kain-Fritsch convection and Rasch-Kristjannsson large scale implemented into the HIRLAM reference system. • Forecast 10-20 % more expensive and even more on vector computers (vector optimization in progress). • Improvement of precipitation over Iberia. 27th EWGLAM & 12th SRNWP Meetings

  20. True Skill Statistic + Equitable Threat Score over Iberia (2-3 months) 27th EWGLAM & 12th SRNWP Meetings

  21. SREPS - Multi-model Multi-boundaries • Models: • Hirlam. • HRM • MM5 • UM • Boundaries • ECMWF • UM • AVN • GME 27th EWGLAM & 12th SRNWP Meetings
