Paper Abstract

In this work we present the application of the recently introduced modal matching technique to meteorological radar data. Showing how it is possible to retrieve, by means of a suitable data processing, more information about rainfall patterns and their evolution. The advantages for shape analysis and recognition of this algorithm, based on the evaluation of the eigenvalues of the dynamic equilibrium equation, are shown. Moreover, shape analysis allows to integrate data from different sources at different scales. Therefore, accurate global analysis and forecasts of rainfall movements can be achieved. The characteristics and implementation problems of this technique are also addressed, as well as some examples of complex artificial shape data. Finally, a case study of a rain even occurred in Northern Italy is shown.
