Rainfall Distribution Inversion Algorithm Based on Mixed-Phase Rainfall Particles
A rainfall distribution inversion algorithm based on mixed-phase rainfall particles is proposed to address the vertical structure characteristics of deep convective rainfall and to consider the problem that the forward model of SAR rain-fall measurement(i.e.,normalized radar scattering cross-section model)ignores the case of supercooled water near the freezing height,which leads to the underestimation of the inversion results of the SAR rainfall distribution inversion algorithm.The scattering attenuation characteristics of mixed-phase rainfall particles are analytically calculated,and the formulation of the inversion algorithm is reconstructed by using the rainfall distribution model with a three-layer structure.The simulation results show that the accuracy of the rainfall distribution inversion algorithm is improved with the configuration of the con-vective rainfall distribution model.
