摘要
导出二维三层（准三维）潮流与起伏地形相互作用而产生内潮波的非线性数学模型，并分别以Ｍ２分潮、Ｋ１分潮为策动期波，数值求解南海东北部大陆斜坡对策动潮波的响应。结果表明：台湾浅滩南面斜坡对Ｍ２分潮响应最为强烈，东沙群岛东面斜坡次之，其余海域无显著响应；对Ｋ１分潮的响应则以一统暗沙东南面斜坡最甚，其次为东沙群岛东南的斜坡，其余海域响应微弱。
A nonlinear quasi-3D mathematical model is derived for internal tides forced by the interaction term of tide currents and topographical gradient, and the response to the forced tidal waves by M2,K1 constituents in the continental slope are solved by this model. The results indicate that the response to the M2 constituent forcing is intensive in the continental slope south of Taiwan shoal, mild in the slope east of Dongsha Islands, and weak in other areas. The response to the K1 constituent forcing is intensive in the slope southeast of Yitung shoal, as in M2 constituent forced case it is mild in the slope east of Dongsha Islands, but weak in the slope south of Taiwan shoal.
