The quasi-geostrophic equations are a set of mathematical equations used to describe the dynamics of large-scale atmospheric and oceanic flows in the presence of rotation and stratification. These equations are an approximation of the full Navier-Stokes equations, focusing on flows that are geostrophic, meaning that the Coriolis force (due to the Earth's rotation) balances the pressure gradient force.
