中文摘要：

基于沿海峡相反方向传播的Kelvin波,导出了因海平面上升导致潮位振幅和位相变化的特征函数。这2个特征函数有一定的空间分布模式,可反映出由于海平面上升引起的潮位振幅和位相的变化哪儿是正,哪儿是负。文中计算了海平面上升1 m所引起的潮位振幅和位相的变化值。可以看出：对于一个给定的角速率ω来说,正变化区域的振幅变化值的平均值和负变化区域的振幅变化绝对值的平均值ω随纬度φ的增加而减小,而对于一个给定的地理纬度φ来说,正变化区域的振幅变化值的平均值和负变化区域的振幅变化绝对值的平均值随ω的增大而增大。在矩形海湾满足边界条件的解当中,Kelvin波占主导地位,因此,2个特征函数能够用来描述矩形海湾和某些实际海湾中因海平面上升引起的旋转潮波系统变化的分布特征。

英文摘要：

Characteristic functions of the changes of amplitude and phase due to MSL rise were derived based on Kelvin waves propagating in opposite directions in a strait. There exist certain spatial distribution models in the two characteristic functions, which can reflect the positions of positive and negative changes in amplitude and phase due to MSL rise. The change values of amplitude and phase caused by 1 m MSL rise were computed. It can be seen that for a given angular speed ω, the average of amplitude change values in the positive change areas and the average of absolute amplitude change values in the negative change areas decrease with φ, whereas, for a given φ, both increase with ω. In a rectangular gulf, it can be found that Kelvin waves are dominant in the solution satisfying the boundary conditions, therefore the two characteristic functions can be used to describe the distribution characteristics of the change of a tidal amphidromic system due to MSL rise in the gulf and some real waters.
