Abstract
ECMWF and Météo-France are developing a new code for operational weather forecasting that includes components both for the variational analysis of meteorological observations and for the prediction model itself. ECMWF has already begun the investigation of the parallelization of the model. This work is the basis of our developments. The parallel version of ARPEGE/IFS uses spectral computations for the dynamic (using 3D transposition) and grid point computations for physics. The full physicss scheme and some options of the semi-Lagrangian are specific to our use of ARPEGE/IFS. The behaviour of this model on the grid point space is described with a partial “physics” solution to the load inbalance.
