  • General discussion
    • The meeting was judged very interesting : some participants would have liked more presentations on both convection permitting scale and turbulence. For sure, more physics presentations are expected during next year workshop.
    • The HIRLAM PM asks whether we still need the half-afternoon of separated program or we could dedicate this period to other session (users session for instance). This question will be discussed within the PMs and the HMG/CSSI .
    • The ALADIN PM reminds the venue of the next workshop in 2012 in Morocco (exact dates and place to be precised).
