Annoucement (May 2016)

The purpose is to present ALARO-1 developments, plans, exchange experience and spread knowledge about the ALARO to a wider ALADIN/LACE/HIRLAM community.

About the scope of the working days

  • share the experience on ALARO-1vA validation, operational use
  • present latest developments ACRANEB2, TOUCANS (shallow convection), CSD, microphysics
  • link with SURFEX
  • further validation, tuning and scope of ALARO-1
  • discuss about plans


Tentative program:

  • Generalities
    • introduction, an overview
    • evaluation of ALARO-1vA (local experiences, reporting the current implementations, ...)
    • physics-dynamics interface: redesign of physics interfaces
    • coupling with SURFEX
    • ALARO-0 performance in climate simulations
  • ALARO-1 overview of current developments
    • TOUCANS: shallow convection
    • radiation: use of prognostic condensates and cloudiness and other novelties
    • precipitations aspects  (diurnal cycle issues, microphysics)
    • deep convection: complementary subgrid drafts; stochastic components
    • set-up of the next versions
      • radiation + TOUCANS + unsaturated downdraft
      • "full" version (radiation + TOUCANS + CSD) implemented in CY43t2
  • Discussion
    • current status, open questions/problems
    • recommended/possible resolutions, GCM tests, MUSC testbed, climate, load/benefits
    • future issues (microphysics, ...)

Three parts will be roughly split over three days, with some flexibility.




Starting Monday (12 September) morning, closing Wednesday (14 September) around noon.
