Abstract:
This documentation describes the digital filtering initialisation (DFI) and its implementation in ARPEGE/IFS. Some theoretical aspects are recalled. The way of implementing the DFI in ARPEGE/IFS is then described, and an organigramme is provided. A namelist is provided.
RESUME:
CETTE DOCUMENTATION DECRIT L’INITIALISATION PAR FILTRES DIGITAUX (DFI) ET LE CODE ASSOCIE DANS ARPEGE/IFS. ON RAPPELLE QUELQUES NOTIONS THEORIQUES. ON DECRIT LA FACON DONT LES DFI ONT ETE CODES DANS ARPEGE/IFS, AVEC PRESENTATION D’UN ORGANIGRAMME. ON FOURNIT UN EXEMPLE DE NAMELIST.
