| 摘 要： | 应用海湾和半封闭矩形海域改进的Taylor问题的解研究海平面上升对M2分潮旋转潮波系统及沿岸潮差的变化.将南黄海概化为一等深矩形海域,初步研究在海平面上升3 m和5 m条件下该海域旋转潮波系统的演化趋势,继而分析沿岸潮差变化特征.初步分析研究表明:随着海平面上升,该海域M2分潮的无潮点有向东南方向偏移的趋势,受此影响,沿岸潮差呈现不同的变化特征,靠近无潮点的左侧及湾顶海岸变化明显,而远离无潮点的右侧及湾顶海岸则变化不大. |

| Abstract: | Based on the analytical solution of the improved Taylor problem in the idealized semi-enclosed rectangular bay,the change of tidal amphidromic system of M2and coast tidal range with the sea level rise is studied in this paper.Schematizing the southern Yellow sea as an constant water depth and semi-enclosed rectangular bay,the evolution trends of tidal amphidromic system of M2and variation features of coast tidal range are analyzed primary under the condition of 3 and 5 meter rise of sea level respectively.The results show that with the sea level rise,amphidromic point in this sea area tends to move to the southeast,and then coastal tidal ranges change present consequently different features,that is,at the left side and bayhead coast near the amphidromic point they change evidently,and little at the right side and bayhead coast far away from amphidromic point.With the sea level rise in future,the result has value reference at the calculation of designing tide level in coast and ocean engineering. |
