The Interpretation and Applications Working Group on Interpretation and Applications explores the ways to use high resolution models used by the members of COSMO. It relies much on verification results which help to find the strenghs and weaknesses of the models, and also to orient the postprocessing methods. In more details, the aims and goals are the following:
- Interpretation: this topic mainly deals with the use of high resolution models by the operational forecasters. The external users of the COSMO models could also be incorporated. A user oriented verification has to be built up in order to look for parameters, seasons, weather situations or events in which the models are good or bad. The results should be summarised in short guidelines or factsheets in text form which should be made available easily for the end users.
- Specific verification: this topic is not redundant with the activities of
working group 5, but explores new methods which can serve the points mentioned in point 1. Fuzzy
verification methods applied on very high resolution models have for instance been evaluated in a
priority project of which the final report can be found here. In a further
stage, the results produced by stratified verification will exploited. A connection with
groups who have expertise in weather type classification will be established.
- Applications, postprocessing: the output of high resolution models are often used as input to application models. These can include hydrology, air quality, aviation, navigation, traffic,... An exhaustive list is difficult to produce and these types of applications depend much on national practices and users. As far as possible the exchange of experiences are promoted by this work group. A field of research is also constituted by the specific postprocessing methods which can be applied to high resolution models. Keywords to this activity are: Kalman filtering, updatable MOS, 1d and 2d models, indices, boosting for recognition of events,...
