CNN reports on the story where the Swiss Meteorology has upgraded to a GPU powered Cray Super Computer to improve their forecasts:

“To guarantee more detailed weather forecasts, the simulations will be based on a grid spacing of 1.1 kilometers, which runs recurrently every three hours,” said Peter Binder, Director General of MeteoSwiss. “This grid spacing makes it possible to predict with more detail the precipitation distribution and the risk of storms or valley wind systems in the Swiss mountains.”

They’re down to a 1.1 km resolution and it runs every 3 hours? Plus the new system reduces power requirements. Plus  the “grid spacing makes it possible to predict with more detail the precipitation distribution and the risk of storms or valley wind systems in the Swiss mountains.”

Yay!
