Spatio-temporal change of coastal current around Shandong Peninsula and transport characteristics of suspended matter

摘要:
基于2014—2018年NOAA/AVHRR遥感数据，在山东半岛海域选取6条剖面，结合海表温度和表层悬浮体的时空变化特征，详细研究了山东半岛沿岸流的年周期变化规律与移动路径。研究结果表明，山东半岛沿岸流年周期变化可分为4个阶段：成长期（10—12月）时开始形成于黄河口附近，沿莱州湾南部向东运移；强盛期（次年1—3月）时山东半岛沿岸流完全成型，扩散带最宽，鼎盛时期北部可以至38°N附近，东部可以至123°E附近，在35°～36°N附近分成NE—SW向的2个分支，主干部分最远可到达胶州湾东部海域，余流沿岸向西南方向转折；衰退期（4—6月）时沿岸流强度减弱，只在山东半岛北部和东部小范围内有微弱的显示；消亡期（7—9月）时基本消失。山东半岛沿岸流在冬季时对悬浮体扩散具有强烈的驱动作用，使其在黄河口南侧与山东半岛北岸-成山头东部海域分别形成呈“弧形”和“条带状”分布的2个高浓度区域。

Abstract:Based on NOAA/AVHRR remote sensing data from 2014 to 2018, six sections were selected in the sea area around Shandong Peninsula, East China. Combined with the temporal and spatial variation characteristics of sea surface temperature and concentration of surface suspension matter, the annual periodic variation and movement path of the coastal current at the six sections were studied. Results show that the annual periodic variation of the coastal current along Shandong Peninsula could be divided into four stages. The first is the growth stage (October to December), during which coastal currents are originated near the Yellow River estuary and move eastward along the southern Laizhou Bay. The second is the mature stage (January to March of the next year), during which the coastal currents are fully formed, and had the widest diffusion zone reaching near 38°N in the north and 123°E in the east. Two branches from northeast to southwest near 35°～36°N could be recognized. The main part reached the eastern sea area of Jiaozhou Bay, and the residual current turned southwest. The third is the decline stage (April to June), during which the intensity of coastal currents weakened but showing only a small range in the north and east of Shandong Peninsula. The fourth is the extinction stage (July to September), and they largely disappeared. In winter, Shandong Peninsula coastal current had a strong driving effect on the diffusion of surface suspension, by which two high-concentration areas in the patterns of "arc" and "strip" distribution were formed in the south of the Yellow River Estuary, and in the area between the north shore of Shandong Peninsula and the east of Chengshantou, respectively.
