摘　　要：根据黄海1939-1999年海洋实测数据集和2010年黄海成山头附近海域海试资料,统计分析了黄海西部沿岸锋温度分布结构、平均强度、宽度、位置分布等特征。实测数据统计分析结果表明,黄海西部沿岸锋具有明显的季节变化特征:春季开始形成并逐步加强,夏季处于强盛期,秋季海洋锋逐渐减弱,冬季相比秋季略有增强的趋势,初春季节海洋锋消亡。海试资料表明2010-08该锋位于20m等深线以西5nmile至以东30nmile之间的海域,且位于40m等深线以西20nmile至以东20nmile之间的海域。On the basis of the datasets from the observations in the Yellow Sea during 1939--1999 and the sea experiments in the Shandongtou region in 2010, the features of coastal front such as the distribution structure, average intensity, width and spatial position of temperature in the western Yellow Sea are ana- lyzed statistically. The results indicate that the coastal front in the western Yellow Sea is characterized with distinct seasonal variations, that is, it begins to form and enhances gradually in spring, becomes a flourish state in summer, weakens gradually in autumn and tends to intensify slightly in winter compared with that in autumn. In the early spring the front disappears. The sea experiment data obtained in August 2010 show that the front is located in the area between 5 knots west of and 30 knots east of the 20 m iso- bath and in the area between 20 knots west of and 20 knots east of the 40 m isobath.
