中国海海面的辐射收支

RADIATION BUDGET OF THE CHINA SEA

利用50年逐次船舶海洋气象资料,计算分析了中国海海面的净辐射气候学分布特点,同时,还讨论了它们的净辐射年变化规律。结果表明,中国海海面的辐射收支关键取决于海面对太阳总辐射的净吸收量;黄海、东海、南海南、北部的净辐射年变化特征不一致,黄海和东海的年变化较大,而南海的年变化较小;而且南海南部的净辐射收入最大。

Using marine meteorological data during 1930—1979 observed by ships,the main featuresof the net radiation of the China Sea are calculated and analyzed.Also,the annual variations ofthe net radiation for the Yellow Sea,East China Sea,the northern and southern South China Seaare discussed.The results show that the net absorption of the global solar radiation by sea surfaceis responsible for the radiation budget over the China Sea.The annual radiation variations over theYellow Sea and East China Sea are larger than those over the South China Sea.And,the positivenet radiation of the southern South China Sea is the largest in the four sea areas.
