4. Jean-Marcel PIRIOU : "Correction of compensating errors in physical packages; validation with special emphasis on cloudiness representation"

Precipitating convection:

The cloud ascent in the ACCVIMP scheme has been modified, in order to introduce a diagnostic vertical velocity and thus change entrainement / detrainement computations. The sensitivity to the environmental humidity is increased. This work is still under progress.

Diagnosing the tropical diurnal cycle of clouds in ARPEGE:

Hovmöller diagrams of outgoing longwave radiation and precipitation fluxes predicted by ARPEGE have been compared to observed ones.

Intercomparison cases from the EUROCS Research project:

Interaction with the leaders of these 3 cases, as co-author of 3 papers. These papers were submitted to QJRMS in July.
