摘　　要：为较准确地了解掌握可以反映南中国海天气和气候特征的云量分布演变特征,利用1999年1月至2009年12月的ISCCP卫星云量资料,通过物理量特征提取、对比分析等方法,研究了南中国海总云量及高、中、低云量的分布演变特征,以及其与其他海域各季节云量季节性变化特征。结果表明:南中国海低云量四季中均表现为由海区向沿岸递减,总云量和中、高云量夏秋季高于冬春季,低云量则相反。对于不同海域的云量细节特征要依据各季节大气和海洋环流变化来细致区分,这样有助于在掌握规律基础上有效制作海域上空云的预报。The ISCCP dataset were employed to both analyze the characteristics of the geographical distribution of various cloud amounts over the South China Sea and compare the seasonal variation in two waters according to the analysis of the cloud amounts over the East China Sea given in another article from January 1999 to December 2009. It is shown that the spatial feature that the low cloud amount decreases from the center of the waters to the shore is stable in four seasons over the South China Sea. It＇s better to distinguish the detailed characteristics about the concrete cloud amount on the basis of the general circulation of atmosphere and ocean in disparate areas ,which will benefit to make specific cloud predictions effectively.
