中国近海海表温度对气候变暖及暂缓的显著响应

基于多套全球海温再分析数据和2种线性趋势分析方法，评估了1958-2014年中国近海海表温度（SST）的变化及其对全球气候变化的响应特征，并与全球平均地表温度特别是与若干重要海区的SST做了比较。研究表明：在全球变暖的显著加速期（1980年代和1990年代），中国近海区域年平均SST表现出更快速的升温特征，其速率达0.60℃/10a，是同期全球平均升温速率的5倍以上；在变暖暂缓期（1998-2014年），中国近海SST出现显著的下降趋势。研究还表明，中国近海区域SST的年代际变化与太平洋年代际涛动（PDO）的位相转换一致，前者SST的快速上升（下降）期与PDO正（负）位相最大值的时期相对应，PDO可能是通过东亚季风和黑潮影响中国近海SST的年代际变化。

Enhanced Responses of Sea Surface Temperature over Offshore China to Global Warming and Hiatus

In this study, we assessed and compared the sea surface temperature (SST) trends between offshore China and other sea regions of interest as well as global mean surface temperature based on four SST datasets. The results revealed an enhanced SST response over offshore China during different periods. During the accelerated global warming periods (1980s and 1990s), SST over offshore China shows faster rising trend than the global mean. The most pronounced warming area is located over the East China Sea, with the rising rate up to 0.60℃ per decade, which is 5 times faster than that of the global mean. While during the hiatus period (1998-2014), SST over offshore China exhibits significant cooling trend. The decadal variability of offshore China SST is closely linked to the Pacific Decadal Oscillation (PDO). The periods with rapid warming (cooling) over offshore China are consistent with the positive (negative) phase of PDO. PDO may affect SST over offshore China through the East Asian Monsoon and Kuroshio Current.
