New High-Resolution Model for Weather and Climate Research

In the PASC project KILOS, the ECMWF, the Swiss National Supercomputing Centre (CSCS), and ETH Zurich are teaming up to develop FVM, a new weather and climate model of ECMWF, adapted to the latest computer architectures. First simulations can simulate small-scale orographic windstorms as observed in northeastern Switzerland (Laseyer storms).

Animation of surface wind in the Schwende valley of Appenzell (Switzerland) during a Laseyer windstorm, as simulated in high resolution with the new FVM model. The gray contours show the height of the topography, and the green crosses mark the location of the two measurement stations in the region. (Animation: The KILOS research team)
