The waveguide condition depends only on the zonal wave number k and the shape of the zonal mean zonal wind (ū) profile. Through the thermal wind relationship, this profile can, in turn, be tied to meridional temperature ...

Waves are also seen in the summer upper mesosphere. A three-dimensional numerical model was used to simulate these waves and to diagnose the physical processes involved. The waves simulated in the model …
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.
