Abstract
Abstract Based on matched scans from the FY‐4A satellite's Advanced Geostationary Radiation Imager (AGRI) and the NASA/JAXA Global Precipitation Measurement (GPM) Core Observatory's Dual‐frequency Precipitation Radar (DPR), the microphysical mechanisms of the derived vertical evolution of cloud effective radius ( R e ) and its correspondence with precipitation droplet growth modes are revealed in this study. The results show that there were two turning points in the R e vertical evolution, which divided the R e profile into solid‐phase, mixed‐phase, and liquid‐phase zones from top to bottom. There were also two turning points in the upper layer of DPR reflectivity, which showed good correspondence with R e turning points in both height and physical sense. The main droplet growth modes in the three zones are nucleation/glaciation, deposition, and riming, respectively. The linkage between R e vertical evolution and droplet growth modes would be useful in real‐time monitoring of cloud microphysical processes.
