Волны Герстнера и их обобщения в гидродинамике и геофизике.
To mark 220 years since the appearance of Gerstner's paper that proposed an exact solution to the hydrodynamic equations, an overview of exact solutions for water waves is given, each of which is a generalization of the Gerstner wave. Additional factors are coastal geometry, rotation, varying pressure on the free surface, stratiécation, compressibility, and background êows. Waves on a rotating Earth are studied in the f-plane approximation, and, in the near-equatorial region, also in the beta-plane approximation. The êows are described in Lagrangian variables. For all waves in the absence of background êows, the trajectories of liquid particles are circles, as in the Gerstner wave (hence, their common nameìGerstner-like).
