These practical exercises were done during the 2nd AROME training course, Lisbon, 4-7 March 2008.

• Introduction to practical exercises (see introduction.pdf) :
  • AROME forecast overview
  • Introduction to AROME code
• PC Package (see PC package.pdf) :
  • Graphics
  • Model on PC
• 1D model tests with MUSC (Modele Unifie, Simple Colonne) for Arpege-Aladin-Arome-Alaro-Hirlam-(IFS)
  (CY31T1 version) by Sylvie Malardel : see MUSC documentation.pdf for more details or MUSC presentation.pdf for the presentation and the exercises 1 and 2.
  • Most of the NWP or research 3D models have a corresponding single column version
    dedicated to the validation of physical parameterizations.
    In the context of the collaboration between Meteo-France and the Aladin and Hirlam
    consortiums and the multiplications of the sets of physics which will be available in the
    Arpege/IFS system, a common 1D tool for physics validations and intercomparisons has been developed from a 2D meridional vertical plane version (for academic cases)
    used with a minimal configuration as a single column model.
  • MUSC documentation : the procedure to be followed in order to run an ideal case with MUSC
  • ascii2fa : initial file and forcing preparation for a 1D case
  • Output, simple diagnostics and
    graphics
  • Exercise 1 :
    • Create a local pack on HPCE with a few
      modifications necessary for running MUSC with this
      new cycle + SURFEX modifications for GABLS1
    • Test the pack with the GABLS1 case
  • Exercise 2 :
    • Modify the mixing coefficient for the wind in the
      turbulent scheme and reactivate the mixing length
      minimum value and rerun the GABLS1 case
• Practical 3D exercice (see 3D exercise.pdf)
  • Run the 3D-AROME model on a small domain on hpce and plot the
    results on your local computer
  • Use the same binary that you have built yesterday for the 1D exercise
  • Make some namelist changes and check the results; changes proposed :
    • Sensitivity to the set up of the
      numerical diffusion
    • Run in Hydrostatics mode
