Model validation and verification

Precipitation forecasts


The prediction of rainfall still poses a major problem to todays weather forecast models, especially in areas with a prominent topography such as the Alps in Switzerland. A quantification of these errors is a coercible prerequisite for the improvement of these forecasts.

High - resolution NWP models


A higher resolution of weather forecast models allows to increase the number of implicitly simulated atmospheric processes and thereby improve the model.

Forecast error quantification based on potential vorticity

Potential vorticity can be used to identify model errors.
