作者利用CloudSat和云气溶胶激光雷达和红外线探路者卫星观测（CALIPSO）卫星三年的数据，首次记录了整个南极洲和高纬度南大洋云量的季节性变化的垂直结构。这些结果为今后的观测和模式研究提供了南半球高纬云量的基准参考，并突出了南极云量的几个以前没有记载的方面和关键特征。这里记录的南半球高纬云量的关键特征包括：1）南半球高纬云量有明显的季节循环，在冬季，南大洋和南极洲的云发生率普遍较高; 2）南大洋云发生率的垂直廓线有两个明显的极大值，一个集中在近地面，另一个集中在对流层上部; 3）云发生率的垂直廓线几乎不连续。
AbstractThe authors exploit three years of data from the CloudSat and Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellites to document for the first time the seasonally varying vertical structure of cloudiness throughout Antarctica and the high-latitude Southern Ocean. The results provide a baseline reference of Southern Hemisphere high-latitude cloudiness for future observational and modeling studies, and they highlight several previously undocumented aspects and key features of Antarctic cloudiness.The key features of high-latitude Southern Hemisphere cloudiness documented here include 1) a pronounced seasonal cycle in cloudiness over the high-latitude Southern Hemisphere, with higher cloud incidences generally found during the winter season over both the Southern Ocean and Antarctica; 2) two distinct maxima in vertical profiles of cloud incidence over the Southern Ocean, one centered near the surface and another centered in the upper troposphere; 3) a nearly discontinu...
