摘要

通过一系列理想化数值模拟，研究了一模超惯性海岸陷波（CTW）的产生。在第一组模拟中，当自由传播的一模内潮入射到海岸上时共振产生 CTW，内波的入射角使海岸上潮汐的投影波数与水深和 CTW 的波数满足三元关系。在第二组模拟中，CTW 是由沿气压方向的潮汐与与 CTW 尺度相同的地形相互作用产生的。在共振条件下，超惯性沿岸滞留波是一种前沿沿岸过程，其沿岸海流幅值可能比产生它的沿气潮或内潮还要大。

The generation of superinertial coastally trapped waves by scattering at the coast

A series of idealized numerical simulations is used to examine the generation of mode-one superinertial coastally trapped waves (CTW). In the first set of simulations, CTW are resonantly generated when freely propagating mode-one internal tides are incident on the coast such that the angle of incidence of the internal wave causes the projected wavenumber of the tide on the coast to satisfy a triad relationship with the wavenumbers of the bathymetry and the CTW. In the second set of simulations, CTW are generated by the interaction of the barotropic tide with topography that has the same scales as the CTW. Under resonant conditions superinertial coastally trapped waves are a leading order coastal process, with along-shore current magnitudes that can be larger than the barotropic or internal tides from which they are generated.

期刊介绍： The Journal of Physical Oceanography (JPO) (ISSN: 0022-3670; eISSN: 1520-0485) publishes research related to the physics of the ocean and to processes operating at its boundaries. Observational, theoretical, and modeling studies are all welcome, especially those that focus on elucidating specific physical processes. Papers that investigate interactions with other components of the Earth system (e.g., ocean–atmosphere, physical–biological, and physical–chemical interactions) as well as studies of other fluid systems (e.g., lakes and laboratory tanks) are also invited, as long as their focus is on understanding the ocean or its role in the Earth system.
