“…(2018) concluded that raindrops tend to be more spherical in typhoon systems based on statistics of ARs from 2DVD raw products. Given the current interest in unraveling the internal kinematics and microphysics of tropical cyclones with polarimetric and dual‐frequency observations (Bao et el., 2022; Didlake Jr. & Kumjian, 2018; Feng & Bell, 2019; Homeyer et al., 2021; Huang et al., 2022; Wu, Zhang, Xie, et al., 2022; Wu, Zhang, Zhang, et al., 2022; Zhao et al., 2019), there is a need for accurate AR parameterizations that bridge those observations and raindrop size distributions. Therefore, the necessity of pinning down an AR parameterization from 3D retrievals appears to be more urgent in tropical cyclones.…”
