dphase_aladfr: Aladin-France operational model forecasts run by Meteo-France for the MAP D-PHASE project

Description

Aladin is the operational model at Meteo-France. The horizontal resolution is 9.5 km, the time step: 415s with a Semi-Lagrangian scheme. There are 46 vertical levels with 15 levels below 3 000 m. The domain of the integration is: (-11.84 W, 33.14E) (25N,56.95N) Physical parameterisation: — the micro-physics scheme use 4 prognostic variables: liquid and ice cloud water, rain and snow. — the convection scheme is based on Bougeault (1985) with a donwdraft Parameterisation. — the operational ECMWF radiation code which is called every 60 minutes. — the burbulence is based on Louis’s function with an interactive mixing length. Aladin is coupled with ARPEGE every 3 hours and has its own assimilation system based on 3DVAR. The post-processing in GRIB files is done on a regular LAT-LON Grid with a 0.1 deg resolution on the DPHASE domain. Aladin-FRANCE daily performs 54h forecasts starting at 0TU, 6TU, 12TU, 18TU (only the 0UTC forecast until 30h is sent) Grid description: DDOM: xfirst: 2.0 yfirst: 43.0 xsise: 161.0 ysise: 71.0 xinc: 0.1 yinc: 0.1 xnpole: 0.0 ynpole: 0.0
