AROME-ALADIN special workshop: Various issues linked to the AROME-ALADIN convergence

It is rather difficult to structure a linear preparatory text for such an issue. Indeed the problem is so multiform and its various aspects so entangled that any ordering of priorities is already a subjective distortion of the overal truth. Let us therefore simply outline that the complete presentation will try and deal with the following topics:

How to preserve the succesfull spirit of the ALADIN cooperation within ambitions and calendars radically different from the usual ones?
How to get back to a less constrained view of scientific innovation?
How to forget the ARPEGE downscaling reflex and think, on the contrary, in upscaling terms, for goals prior to the nominal AROME’s ultimate use everywhere?
What are concretely the new challenges and how to redistribute priorities for facing them, including in terms of more deported maintenance efforts (for a temporary transition period)?
Which ’new generation’ of specialists do we need for such unusual (in ALADIN’s world) perspectives?
What is the in-depth difference between the launching of ALADIN in 1990 and what will be at stake more than 12 years later?
Which scope exists for a truly mutually beneficial approach of the AROME-ALADIN convergence and how to offer guarantees on each side for its realisation?

It is hoped that even a rapid scan of all these issues will offer the needed incitation for an open, mind-stimulating and fruitful second part of the workshop.
