The HARMONIE System (Presentation, March 2008)

Presentation of Sami Niemelä during the 2^nd AROME training course, Lisbon, 4-7 March 2008 : "Experiences on AROME at HIRLAM institutes –
the HARMONIE system" by Sami Niemelä, Ulf Andrae, Lisa Bengtsson and Sander Tijm.

• What is HARMONIE and the HARMONIE system?
  • During 2004 and 2005 HIRLAM and ALADIN consortia decided to
    deepen already existing cooperation in NWP. One of the main goals
    of the new cooperation is to develop a km scale
    operational NWP
    system.
  • HARMONIE :
    Hirlam Aladin Regional/Mesoscale
    Operational NWP In Europe
• Recent developments within HARMONIE.
• Near future plans
  • PHYSICS
    • SURFEX developments (inclusion of forest tile).
    • Inclusion of Lake scheme in SURFEX.
    • Development of EDMF
    • Impact of boundaries and initial conditions on AROME.
    • Impact of deep convection parameterization on resolved deep convection.
    • Radiation scheme intercomparison and optimization.
  • DATA ASSIMILATION (according to work plan)
    • Construction and testing of a common 3DVAR
      system based on ALADIN.
    • Setup of a mesoscale surface DAsystem
      (soil, water surface, snow etc.).
    • Remote sensing data: radar reflectivity/winds, GPS, satellite data.
