摘　　要：根据 1999—2001 年月平均海面高度资料讨论了青岛和胶州湾附近海面高度的年变化。结果表明：各验潮点夏季的海面高度普遍高于冬季的海面高度，具有明显的季节变化。此外，夏季胶州湾口外的海面高度低于胶州湾内的海面高度，表现为由北向南下倾的海面坡度。同时说明了形成这种海面坡度的原因。文章还利用动力学原理探讨了夏季风和海面坡度的动力作用，及其对月平均海流的影响，强调指出了夏季风和海面坡度所产生的压强梯度力的重要性。Based on the monthly mean sea level data obtained from many years of tide gauge measurement, the annual variability of the sea level near Qingdao and Jiaozhou Bay is studied and discussed in this paper. It is indicated in the study results that the sea surface height at all the tide gauges becomes higher in summer than that in winter, with an obvious seasonal variability. Furthermore, the sea surface height measured at a short distance outside the bay is lower than that in the bay, showing a sea surface slope downward from north to south. The reasons for the slope are explained as well. The dynamic action of the summer monsoon and the sea surface slope, and their effects on the monthly mean current are studied by means of dynamic principles. The importance of the summer monsoon and the pressure gradient generated by the sea surface slope, with their effects on the alongshore current, is pointed out and emphasized in this paper.
