Wavenumber–frequency diagram
A wavenumber–frequency diagram is a plot displaying the relationship between the wavenumber (spatial frequency) and the frequency (temporal frequency) of certain phenomena. Usually frequencies are placed on the vertical axis, while wavenumbers are placed on the horizontal axis.[1][2]
In the atmospheric sciences, these plots are a common way to visualize atmospheric waves.

Origins
In general, the relationship between wavelength , frequency , and the phase velocity of a sinusoidal wave is:
Using the wavenumber () and angular frequency () notation, the previous equation can be rewritten as
On the other hand, the
Analyzing such relationships in detail often yields information on the physical properties of the medium, such as density, composition, etc.
