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

EUROCS project :

The wet prognostic TKE (Turbulent Kinetic Energy) scheme developed by Pascal Marquet has been introduced in the ARPEGE/ALADIN SCM. Some tests with this prognostic TKE were performed on the diurnal cycle of the PBL over desert areas. A case of diurnal cycle of deep convection over land was studied within the ARM /GCSS /EUROCS framework. Hovmöller diagrams of the diurnal cycle of ARPEGE precipitations in the Tropics were compared to the results from Yang and Slingo (MWR 2001). This was presented at the EUROCS workshop in Madrid, in December.

CLOUDNET project :

Write-up with Damian Wilson (Met-Office) of a paper "user requirement document" to explain to the observational community the expectations of the modelling community in this project. Modifications of some DDH codes to fit the requirements of the CLOUDNET model database.

Presentation in the CLOUDNET workshop in Utrecht: "How to improve a cloud model's physics from in-situ data like radar and lidars ?"
