Homogeneous Geostrophic Flows and Linear Barotropic Waves

Arpit Agarwal

Homogeneous Geostrophic flows, which are homogeneous flows with small Ekman and Rossby Numbers, will be discussed along with the governing equations. The generalized form of equations for non-geostrophic flows will also be presented. I will then talk about the Linear Barotropic waves. The study of these waves is a wise approach to gain an insight into GFD by understanding the linear processes first before exploring the complex non linear dynamics. Examples of linear barotropic waves i.e. Kelvin waves and Inertia-Gravity (Poincare) waves will be discussed along with the mathematical formulation.
