Analysis of regional differences of forecasts with the multi-layer AMT-model in the Netherlands

This paper describes the research of predicting regional differences in ABL parameters with the multi-layer AMT-model.
The results are also compared with the model output of ECMWF' s NWP-model.
First the background of this research is given. Subsequently three case studies are discussed and an objective comparison is given. The AMT-model is able to predict regional differences in ABL parameters but it has the same skill as the ECMWF-model. Nevertheless the AMT-model is a useful tool, which will give the forecaster a quick indication if regional differences will occur in the next 12 hours.
