Rossby waves, also known as planetary waves, are a type of inertial wave naturally occurring in rotating fluids. They were first identified by Sweden-born American meteorologist Carl-Gustaf Arvid Rossby. They are observed in the atmospheres and oceans of Earth and other planets, owing to the rotation of Earth … See more Atmospheric waves Atmospheric Rossby waves result from the conservation of potential vorticity and are influenced by the Coriolis force and pressure gradient. The rotation causes fluids to turn to the … See more Free barotropic Rossby waves under a zonal flow with linearized vorticity equation To start with, a zonal mean flow, U, can be considered to be perturbed where U is constant in time … See more • Rossby, C.-G.
