RESUMO

This paper briefly describes methodology of precipitation and turbulence classification based on data retrieved by the Doppler-polarimetric radar. Not only classical parameters of turbulence such as eddy dissipation rate are integrated into classification procedure but also the polarimetric ones and the parameters based on the averaged Doppler velocities analysis. The technical complexity of this procedure and scientific importance of this problem are obvious. The classification procedure based on fuzzy logic takes place after detailed processing of echo signal and informative parameters computation. This allows us to distinguish between different types of precipitation and turbulence intensities. The classifier makes the decision about precipitation type and turbulent motion intensity based on simultaneous analysis of all of the informative parameters.
