| 摘 要： | 台湾东北部,黑潮次表层水常年入侵东海陆架。但是黑潮次表层水入侵的季节变化规律,尚存在很多不明之处。本文基于2009至2011年间东海4个航次的CTD实测数据,研究了黑潮次表层水入侵东海过程的季节变化规律,发现:黑潮次表层水入侵在春末夏初开始加强,夏季最强,秋季开始减弱,冬季最弱。入侵的黑潮次表层水起源深度也随季节变化有所不同。另外,结果还表明黑潮次表层水入侵存在明显的短期变动。

| Abstract: | The Kuroshio subsurface water intrusion onto the East China Sea continental shelf is a year-round phenomenon to the northeast of Taiwan. However, the seasonal variation of the Kuroshio subsurface water intrusion still remains unclear. In this paper, the seasonal variation of Kuroshio intrusion onto the East China Sea continental shelf is investigated based on the CTD (conductivity temperature depth) data obtained from the four seasonal cruises of the East China Sea from 2009 to 2011. It is found that: the intrusion strengthens in late spring, strongest in summer, weakens in fall and becomes the weakest in winter. The depth of origin of the intruded Kuroshio subsurface water also varies with season. In addition, there exists significant short-term variability of the subsurface intrusion. |
