ICON-D2

The ICON-D2 model of the Deutscher Wetterdienst (DWD) is a forecast model, which operates for the very-short range up to +27 hours (+45 hours for the 03 UTC run). Due to its fine mesh size, the ICON-D2 especially provides for improved forecasts of hazardous weather conditions, e.g. weather situations with high-level moisture convection (super and multi-cell thunderstorms, squall lines, mesoscale convective complexes) and weather events that are influenced by fine-scale topographic effects (ground fog, Föhn winds, intense downslope winds, flash floods). The model area of ICON-D2 covers Germany, Benelux, Switzerland, Austria and parts of the other neighbouring countries at a horizontal resolution of 2.2 km on a native triangular grid.
