====================================================

The lecture notes emphasize the serendipitous connections between applied mathematics and geophysical flows in the style of modern applied mathematics, where rigorous mathematical analysis as well as asymptotic, qualitative, and numerical modeling all interact to The author elucidates in a concrete way dynamical challenges concerning nonlinear analysis of the 3D quasigeostrophic and rotating Boussinesq equations. He employs the simplifying assumptions of the Boussinesq and hydrostatic approximations to the governing equations of baroclinic and barotropic viscous compressible rotating fluid flow. In this talk, I will overview some recent results related to the Ostrovsky equation [1]. Firstly, I will discuss the e ects of the parallel shear ow on internal waves in a rotating ocean [2, 3]. We found rst examples when the shear ow can change the sign of the rotation coe cient in the Ostrovsky equation, leading to unusual dynamics [3].

Non-Hydrostatic, stably-strati ed and rapidly rotating ows 3 in both cases to reduce the complexity of the full Boussinesq system. When the Froude number is small but the Ross number is order-one one can make the hydrostatic approximation to arrive at the so-called primitive equations. When the Rotating and stably stratified Boussinesq flow is investigated for Burger number unity in domain aspect ratio (height/horizontal length) < 1 and = 1.To achieve Burger number unity, the non-dimensional rotation and stratification frequencies (Ross and Froude numbers, respectively) are both set equal to a second small parameter < 1.Non-dimensionalization of potential vorticity dispersive, and rotational effects, governing equations of the Boussinesq type are derived to model the evolution of an initial disturbance in a two-layer rotating fluid. The numerical study is based on these equations which are analogous to the Boussinesq equations of shallow-water The classical Boussinesq equation includes the weak nonlinear and Boussinesq equations for a stratified fluid in a gravitational field on a rotating In order to include viscous effects in a qualitative manner, we may introduce a linear friction.

The derivations of the equations of Boussinesq and of Korteweg and De Vries are very similar. Both authors consider long waves in a shallow basin with rectangluar cross section; the fluid is assumed incompressible and rotation free, and there is no friction, also not along the boundaries of the On the qualitative theory of the rotating Boussinesq and quasi-geostrophic equations Maleafisha Joseph Pekwa Stephen Tladi 2017 Quaestiones Mathematicae 1 Crossref.

The author studies the rotating Boussinesq equations describing the motion of a viscous incompressible stratified fluid in a rotating system which is relevant, e.g., Long time behavior of the two-dimensional Boussinesq equations without buoyancy diffusion.
