| 摘要: |
| 利用中国科学院海洋研究所“中国海洋科学数据库”历史资料并结合Pathfinder 卫星遥感资料, 对中国近海的海表面温度(SST)多年变化情况进行了分析讨论, 给出了变化趋势。针对1963～1996 年和1985～1996 年两个时间段, 对夏季和冬季中国近海SST 的长期变化趋势进行了分析。结果表明, 在中国近海除个别海域外, 增温是主要的特征, 其中冬季增温趋势更为明显。对若干代表性海域SST 的时间序列分析, 表明在外海海域历史资料和卫星资料有较高的一致性, SST 自80 年代中期以来增温更加显著。 |

| Abstract: |
| Using Institute of Oceanology, the Chinese Academy of Sciences(IOCAS) ‘China Marine Science Database’ historical data and the Pathfinder satellite remote sensing data, the spatial variations in the long-term variation of sea surface temperature (SST) were analyzed over the China seas in summer and winter during 1963~1996 and 1985~1996. The results displayed warming was the main feature except for a few areas in the China seas, which was more significant warming trend in winter. High consistency was found in both datasets through representative areas analysis. The selection of time period and stratification in summer played important roles in the trend of SST. It becomed much warming since mid-80s, which was consistent with the IPCC report. The results have improved our understanding of the marginal seas responses to the global change. |
