ABSTRACT
A method for reconstruction of cross section of rainfall situations with precipitation radar data
based on wavelet analysis of Multi-Resolution Analysis (MRA) which allows extract a peak of the
radar reflectivity is proposed in order to detect bright band height. It is found that the bright band
height can be estimated by using the MRA with the basis of Daubechies wavelet family. It is also
found that the boundaries in rainfall structure can be clearly extracted with MRA.
