Application of C-band polarimetric radar on rainfall-type classification

The rainfall-type classification method which gives a judgment of the presence of the melting layer in addition to a conventional convective-stratiform classification was developed using a C-band polarimetric radar. The convective-stratiform separation was conducted based on the horizontal Z_hh field. The melting layer was detected using the vertical profile of rho_hv. Four rainfall types are identified by a combination of these two classifications: 1) convective rainfall with melting layer, 2) convective rainfall with no melting layer, 3) stratiform rainfall with melting layer, and 4) stratiform rainfall with no melting layer.
