摘要(Abstract)：

基于2009年夏季中潮时胶州湾湾口薛家岛-团岛断面的走航ADCP观测数据,分析了胶州湾湾口断面海流时空分布特征及影响因素。结果表明:湾口处海水运动以潮流为主,总体表现为驻波性质,强流发生在涨、落潮中间时刻。受岸线诱导,湾口海流在涨潮(落潮)时呈西北(东南)向,流速在断面上主要表现为南北方向上的变化。平流项引起的"潮流调整"效应使得断面北侧西向海流和南侧东向海流被加强,造成海流东西分量在水平方向上存在不对称性现象,即南北两侧海水运动涨、落潮不同步,欧拉余流呈现"北进南出"的形态。同时,东风分量会使得断面中心区域产生"表进底出"形态,而南北方向欧拉余流结构受风影响较小。
