Using airborne Ka-band probe radar (KPR) and cloud probe data obtained on 16 June 2021, the microphysical structures and particle characteristics in a stratiform cloud case with embedded convection were studied. At the mature stage, ice particles with sizes between 200 and 600 mu m, including plates and linears, were predominant in the stratiform cloud regions, and the maximum particle concentration was greater than 80 L- 1; however, particles larger than 600 mu m, such as plates, irregulars, and aggregates, were predominant at the edge of the stratiform cloud system, and the maximum particle concentration was less than 3.5 L- 1. The irregulars at the edge of the mature stratiform cloud region exhibited larger sizes compared to those in the inner region, while their occurrence frequency was significantly higher than that within the inner region of the mature stratiform cloud. In the embedded convection cloud region during the stratiform dissipation stage, particles ranging from 125 to 625 mu m were predominantly composed of plates, irregulars, and spheres (droplets). The particle concentration in this region was significantly higher compared to that observed in the stratiform cloud regions. We found that the average area of linear, spherical, plate, and dendritic particles in the stratiform cloud region was larger than that in the convective cloud region. The average area of graupel and aggregates in the embedded convection cloud region was larger than that in the stratiform cloud region. Moreover, we found that the larger the average area of graupel was, the lower the proportion of particles in the inner region of the mature stratiform cloud was.
