Abstract
This study analyzes simulations of the West African Monsoon with the regional climate model PROMES. The simulated period is December 1999 to November 2007, with boundary and initial conditions taken from the ECMWF analysis. The effect of several parameterization changes on the simulated monsoon is examined. The main source of data to compare the simulation results is the corresponding ALMIP offline simulation with ORCHIDEE land surface model, the same used in PROMES coupled simulations. ALMIP output data include land-surface fluxes and soil fields, which are taken as reference fields for comparison with PROMES results. The simulation of the northward extension and the intensity of the monsoon rain is found to depend strongly on the parameterizations. In contrast, the timing of monsoon onset and of active and break phases of the monsoon doesn't change much with the different parameterizations, which suggests a clear influence of boundary conditions on the simulated intraseasonal variability.
