摘要(Abstract)：

通过对HadISST1资料1945～2006年海表温度(SST)的分析,发现在东中国海SST具有明显的长期升高的线性变化趋势,平均每年升高0.015℃,在这62 a共升高了0.9℃。其中,东海的升温现象最为突出,从福建和浙江两省沿岸向东北方向扩展的大片海域,是整个东中国海SST变化最大的所在。由于台湾海峡常年向北的流动和台湾岛东北侧向北的黑潮水入侵在1945～2006之间得到了相当程度的加强,它们对热量平流输运的增加有利于东中国海SST长期升高。同样起到促进作用的还有海面风场所控制的垂向卷夹过程。海面净热通量的变化抑制了东中国海SST的长期升高趋势。研究结果显示,东中国海SST的长期变化趋势极有可能是受到太平洋长期变化的影响。
