英文摘要 | The vertical evolution of the cloud effective radius (R-e) reflects the precipitation-forming process. Based on observations from the first Chinese next-generation geostationary meteorological satellites (FY-4A, Feng Yun 4), we established a new method for objectively obtaining the vertical temperature vs. R-e profile. First of all, R-e was calculated using a bispectral lookup table. Then, cloud clusters were objectively identified using the maximum temperature gradient method. Finally, the R-e profile in a certain cloud was then obtained by combining these two sets of data. Compared with the conventional method used to obtain the R-e profile from the subjective division of a region, objective cloud-cluster identification establishes a unified standard, increases the credibility of the R-e profile, and facilitates the comparison of different R-e profiles. To investigate its performance, we selected a heavy precipitation event from the Integrative Monsoon Frontal Rainfall Experiment in summer 2018. The results showed that the method successfully identified and tracked the cloud cluster. The R-e profile showed completely different morphologies in different life stages of the cloud cluster, which is important in the characterization of the formation of precipitation and the temporal evolution of microphysical processes. |
