Abstract (EN): The sequential simulation of atmospheric flows over complex terrain using Computational Fluid Dynamics tools (CFD) leads normally to very large time-consuming runs. With the present day processors only the power available using parallel computers is enough to produce a true prediction using CFD tools, i.e. running the code faster than the evolution of the real weather. In the present work, the parallelisation strategy used to produce the parallel version of the VENTOS (R) CFD code is shown. A sample of the results included in the present abstract is enough to show the code behaviour as a function of the number of subdomains, both number and direction along which the domain splitting occurs, and their implications on both the iteration number and code parallel efficiency.
