Previous meetings:

     coordination meeting in Budapest, March 2002    
     P/C coordination meeting in Toulouse, March 2002

People:

     same list as defined in coordination meeting in Budapest
     + G. Skok (Si), new person supposed to work with the SL horizontal diffusion
      - C. Smith (Uk), who is going to finish his ALATNET work at the end of July
      - A. Trojakova (Cz), who has finished her master thesis and is now dealing with a different topic

Actions:

     The work on NH dynamics (P/C scheme, new variables) is still going on, although the end of this year seems to be too restrictive limit to be ready with the stable and optimal version. (PS, PB, RB, JV, JM)
      Lower (and upper) boundary definition: end of the work of CS and phasing it at the end of July in Toulouse; no successor defined - the work will be probably distributed into the NH group.
       Radiative upper boundary condition: the work is actually frozen, anyway there is a interest to go further on (MJ)
    Nonlinear horizontal diffusion: final customisation, extension to NH dynamics and solving the remaining problems in semi-Lagrangian gridpoint diffusion and adding some nonlinearity into the spectral horizontal diffusion (FV, GS)
       Design of an improved filtering of orography (KS,?)
       Relaxation of the thin layer hypothesis ? (KY, AN

Validation tools for high resolution dynamics:

       Scania case
      Alpia case

External comparison:

      interest to compare NH ALADIN results with the meso-NH model (a call for distribution of the AROME materials into the ALADIN community) (JFG, CF)
      UKMO - need of some coordinator for this job (JV volunteered for this)
