Abstract

We present an explicit exact solution to the nonlinear governing equations in the $\beta$-plane approximation for internal geophysical water waves propagating at an arbitrary latitude. Such a solution describes oceanic waves in the presence of a constant underlying current, which propagate eastward above the thermocline and beneath the near-surface layer where wind effects are confined.

Keywords
