This paper presents a parallel finite element method for the analysis of orog raphic wind flow and rainfall. The Kessler model, which is the model for warm rain, was used for the governing equation. For the governing equation of wind flow, the unsteady Navier-Stokes equation based on Boussinesq approximation was used. The SUPG and PSPG methods were uemployed for the stabilization method. Parallel implementation based on domain decomposition method and MPI was carried out on a PC cluster. The present method was applied to the analysis of orographic wind flow and rainfall past a semicircular hill and an actual mountain area. The effect of parallelization on the efficiency of the computation was also examined.
