  Sommaire  

 Abstract:

This documentation has the aim to give a general overview of the ARPEGE/IFS, ALADIN and AROME models, for beginners or for someone which knows some specific points but has no general overview of the whole models. It can be seen as a synthetic sum-up of some other documentations, and it contains also a list of references as complete as possible which form the set of documentations.


 RESUME:

CETTE DOCUMENTATION A POUR BUT DE DONNER UN APERCU GENERAL DE CE QUE SONT LES MODELES ARPEGE/IFS, ALADIN ET AROME ET DE LEUR CONTENU, SANS TROP ENTRER DANS LES DETAILS, ET DU MEME COUP VA SERVIR DE DOCUMENTATION D’INTRODUCTION A DIVERSES DOCUMENTATIONS BEAUCOUP PLUS DETAILLEES ET BEAUCOUP PLUS CIBLEES AUSSI QUI EXISTENT DEJA. CELA SERA EN QUELQUE SORTE UN RESUME LE PLUS SYNTHETIQUE POSSIBLE DE LA DOCUMENTATION EXISTANTE. CETTE DOCUMENTATION GENERALISTE CONSTITUE UNE SORTE D’``ARPEGE POUR LES NULS" ET EST DESTINEE EN PRIORITE AUX DEBUTANTS ET AUSSI A CEUX DEJA PRATIQUANTS QUI ONT UNE CONNAISSANCE TRES PARCELLAIRE DE CES MODELES ET UNE VISION D’ENSEMBLE RESTANT A ACQUERIR.
