AROME prototype
Access of this software is strictly restricted to staff of the National
Meteorological Services of the Aladin partner countries, pending clarification
of the Méso-NH and Aladin software licensing policy in the next Aladin Memorandum
of Understanding. Prior authorization to redistribute the Arome software to third
parties must be requested to CNRM/GMAP.
The AROME prototype is built upon the dynamical kernel of ALADIN-NH. The physical package is imported from the research model Méso-NH (GMME-LA). The two worlds are separated (schema). The communication between the two worlds are performed thanks to interfaces that were written for the prototype.
The routines of the physical parametrisations are the ones of Méso-NH model (MASDEV47bf), without any major change. Some minor changes were necessary in 5 MesoNH routines (turb,turb_ver_dyn_flux, tke_eps_sources, average_rad and modd_parameters). These modifications will be included in the next MesoNH cycle under a specific AROME key declared on MesoNH. .
The prototype, developped on pre_cycle 27has been phased on the main version of Cycle 29T2. The call of the mesoNH physics is done in Interface 1 with apl_arome (which replace aplpar in the AROME world). For the prototype, we have created some new routines corresponding to the interface1. We also modified some ARPEGE/ALADIN routines (most of them to update the R and Cp calculations according to new microphysics ).
