This paper experimentally and theoretically examines the scattering properties of simulated non-spherical hydrometeors including water oblates, ice oblates and ice sphere-cone-oblates,in terms of the backscattering cross-section and the differential reflectivity.The experimental measurements of the backscattering cross-sections of non-spherical hydrometeor samples were performed in the Electromagnetic Scattering Laboratory of China National Space Industrial Corporation.Meanwhile,the backscattering cross-sections have been computed with the transition(T) matrix method.The theoretical results are compared with the experimental data,showing that the calculations are consistent with the observations in general.Experimental and theoretical analyses indicate that the backscattering cross-section of non-spherical particles increases as the particle size parameter increases,and fluctuates when the sizes are larger under the effect of resonance scattering.Differential reflectivity ZDR of water oblates in natural rainfall is always greater than 0dB whereas ZDR of hailstones may be negative.There is a good linear relationship between differential reflectivity and aspect ratio of a particle.These derivations agree with the literature and can be used to identify the presence of hail particles and distinguish between plate-type and columnar-type hydrometeors.In this study,the measuring experiment and the T-matrix method calculations for the scattering of simulated raindrop and ice particles are also briefly described.
