摘要

利用高分辨率遥感海表温度和海表面风场数据,通过经验正交分解(EOF)和合成分析等方法对春季(3—5月)东海黑潮海温暖舌和海表面风场的年代际变化特征进行分析。结果表明:春季黑潮海温暖舌存在明显的年代际变化特征,在1996/1997年发生由弱到强的位相转换,该年代际变化主要受到北太平洋涡旋振荡(NPGO)的调制。进一步研究表明,与气候态相反,春季黑潮海表温度和风场散度在年代际尺度上表现出显著的负相关关系,合成分析表明,该现象主要是由黑潮西侧东海陆架海域海温的异常增暖所造成。

Abstract

Based on the high resolution satellite Sea Surface Temperature (SST) and wind data, the decadal variation of the warm tongue and sea surface wind field of East China Sea (ECS) Kuroshio during spring (March-May) were analyzed using the Empirical Orthogonal Function (EOF) and Composite Analysis methods. The results show that: the Kuroshio warm tongue in spring exists significant decadal variation, and experiences a phase change in 1996/1997. The phase change is mainly influenced by the North Pacific Gyre Oscillation (NPGO). Further study find that there is a significant negative correlation between the SST and wind divergence field on decadal time scale. Composite Analysis indicates that the abnormal warming of continental shelf in ECS mainly influence the negative correlation.
