沿大陆架流动的海岸洋流是全球海洋复杂的动力特征。本章从大振幅陆架波的角度描述了沿海洋流的演变。文中还描述了实验装置和过程,并描述了逆行水流经过海岬时产生的大振幅波的演变特征。本章简要回顾了非线性波动理论和数值模拟的准地转(QG)方程。它将非线性架波理论应用于环形通道。本章描述了QG方程的数值格式。比较了理论、数值解和实验在预测大振幅破波特性方面的技巧。最后,本章总结了这些发现,并将结果与以前的地形罗斯比波和海岸流的研究联系起来。
Coastal currents flowing along continental shelves are a complex dynamical feature of the global ocean. This chapter describes the evolution of a coastal current in terms of large‐amplitude shelf waves. It also describes the experimental setup and procedure and characterizes the evolution of large amplitude waves generated by retrograde flow past a headland. The chapter briefly reviews the quasi‐geostrophic (QG) equations that underlie the nonlinear wave theory and numerical simulations. It adapts nonlinear shelf wave theory to the annular channel. The chapter describes the numerical scheme for the QG equations. It compares the skill of the theory, numerical solutions, and experiments in predicting the characteristics of large‐amplitude wave breaking. Finally, the chapter summarizes the findings and relates the results to previous studies of topographic Rossby waves and coastal currents.
