Abstract :
A new approach to climate simulation uses geodesic grids generated from an icosahedron and could become on attractive alternative to current models. We implemented an atmospheric general circulation model using a geodesic discretization of the sphere. Our model uses the message-passing interface and runs efficiently on massively parallel machines.
