从混合伽马分布族出发，提出了一种三参数有界分布来刻画全球海洋部分总云量和低云量的概率密度分布。作者推导出了这种分布的连续形式和离散形式，可以直接应用于云量报告。该分布被应用于志愿观测船(VOS)在过滤了月球照度较差的夜间观测后报告的1950年至2011年期间的云层特征。所建议的分布对数据具有很高的拟合优度，并且能够很好地捕捉不同形状的概率分布。作者给出了所选60年期间派生分布参数的季节气候特征，并证明了将基于PDF的概念应用于云量分析可以识别出可以产生类似平均云量的地区。
AbstractThe authors suggest a three-parameter bounded distribution from the family of mixed gamma distributions for characterizing the probability density distributions of fractional total and low cloud cover over the global oceans. The authors derive both the continuous form of this distribution and its discrete counterpart, which can be directly applied to cloud cover reports. The distribution is applied to the cloud cover characteristics reported by voluntary observing ships (VOS) for the period from 1950 to 2011 after filtering nighttime observations with poor lunar illumination. The suggested distribution demonstrates a high goodness of fit to the data and good skill in capturing probability distributions with different shapes. The authors present seasonal climatologies of the parameters of the derived distribution for the chosen 60-yr period and demonstrate that applying the PDF-based concept to the analysis of cloud cover allows identification of areas where similar mean cloud amounts can be produc...
