| Abstract: | In order to distinguish the different phases of hydrometeors by using a dual-linear polarization radar, in this work we have calculated the backscattering, extinction and absorption cross sections of oblate spheroidal and conical model hails with different phases by using the extended boundary condition method for an inhomogeneous body.We have got the ZDR and ZH values of these model hails and their extinction properties at 5.6 cm wavelength.This work has provided an operational approach to identify hail by using radar. |
