摘　　要：本文分析了１９００～１９９０年间全球海洋总云量。为消除资料序列中非气候因素的影响，序列被分为３个时段进行讨论。发现本世纪内与气候增暖的同时全球海洋云量有明显增加，但云量变化落后于全球平均气温变化１～４年，落后于全球平均海温１～２年，且云与温度变化的关系在不同气候带不同，这可能是不同气候带上主要云型不同，以致产生的辐射强迫效应不同。Historical data of total cloud amounts over global oceans during 1890-1990 are analysed.The amount of clouds over global oceans has increased in accompany with global warming since the end of 19th century. The growing warming of climate and the general circulation systems have influenced the variation of cloudiness.It is found that the variation of cloud amounts lagged behind global mean air temperature about 1 ～ 4 years,but lagged behind the sea surface temperature for about 1～2 years.The correlation between cloud and temperature has opposite signs in different climate zones, mainly due to the difference of dominant cloud types in different climate zones.
