Like a sound wave, there are compressed and dilated regions in the air. But do compressed regions also occur in winds. If one considers squalls, they feel like a compressed region of air. Perhaps they are too great to be considered as a kind of amplitude, but is there anyway a kind of wave in wind?

In the other question/answer is not mentioned anything about forming waves. So does wind behave (perhaps only a little bit) with sound-wave compressions and dilations?

  • $\begingroup$ I wouldn't really say so because wind travels up and down, and in spirals, whereas waves just travel fairly straight and radially. $\endgroup$ Oct 22 '18 at 8:00
  • $\begingroup$ Chaos, flow and turbulence describe wind, wave is a misnomer. Air is an elastic medium which flows like a fluid, so there are compressed zones, which don't have a backwards motion... When you blow smoke from a cigarette, is it a bit like a sound wave? Not technically. $\endgroup$ Oct 23 '18 at 20:29

Yes, there are a lot of waves in wind. The wave you may be looking for is called a gravity wave (aka buoyancy wave). To name a few other waves Rossby Waves, Gravity Waves, Inertio-Gravity waves, Sound Waves, Kelvin Waves

I am sure there are more than just those few waves out there.


Roughly, every 12 hours one side of the earth faces the sun while the other does not. And vice versa.

Roughly, every 6 months, depending on where you are on Earth, it gets cold or it warms up.

This is a very primitive model but, in essence, some natural phenomena (including some types of winds) behave like a wave because the forcing is wave like.

There are waves everywhere in nature. The tides. The Jet Stream. The El-Niño (Rossby wave). The global ocean conveyor belt. They are all waves.

Regarding the second part of the question, sound propagation is much faster than the waves we are talking about here. These waves are driven by gravity (and coriolis) so they are typically slow in comparison to the speed of sound. In fact, when we study this phenomena we typically omit acoustic effects.


When I watch wind travel across a grass plain, the top of the grass like like a wave. So if the movement of wind applied a consistently constant force, the grass would just all lean consistently across the field until the wind died. Instead, the grass waves lengthen and narrow according to the speed or degree of force of the wave trough.


I wish to provide a counterbalance argument. it's just not wavy, it's a chaos of pressure-fronts, wind is doughnuts, and waves have equilibrium points and transmission media.

enter image description here enter image description here vs enter image description here enter image description here Scientific litterature doesn't use the word wave to describe squalls and pressure fronts, and clouds also illustrate the general behaviour of wind. Atmospheric stratification can generate 2D boundary wave clouds which form on stratospheric 2D pressure and temperature boundaries, and on oil-water boundaries: https://en.wikipedia.org/wiki/Wave_cloud enter image description here

Wind follows laws of turbulence and chaotic flow displacement, whereas waves travel backwards and forwards on an equilibrium point. Waves are energy displacement with a radial wave front, whereas squalls are not radial. When we look at clouds, generally there's no wave distributions visible.

To view what a squall does, it's best to consider what smoke does. The smoke doesn't displace air using the elasticity of air, like a sound wave, it actively flows and generates a pressure front which displaces air sideways as much as forwards, it's quite a complex effect which is not totally like waves.

    $\begingroup$ I think you are mistakening what air does on a microscale, as compared to the macroscale. For example, things like gravity waves (aopa.org/news-and-media/all-news/2017/march/…) and Rossby waves (en.wikipedia.org/wiki/Rossby_wave) highlight the flaws in your definition. $\endgroup$ Oct 23 '18 at 20:10

    $\begingroup$ He was talking about sound waves, sound waves are not chaos, they are simple. wind is chaos, not waves. so I was saying that sound waves all rebound backwards and forwards. Wind does not, it flows and spirals... How can wind be like a compressed sound wave if it doesn't have a sine or backwards forwards movement? $\endgroup$ Oct 23 '18 at 20:19

    $\begingroup$ If you look back at the initial question, past the edits that specify sound waves exactly, But either way, the derivation of the sound wave invoke the Navier-stokes and continuity equations, which form the equations governing wind (en.wikipedia.org/wiki/Acoustic_wave_equation). The same 'laws of turbulence' are also derived via the Navier-Stokes equations.(en.wikipedia.org/wiki/…) $\endgroup$ Oct 23 '18 at 21:28
  • $\begingroup$ That's very interesting, what's the frequency of a wind wave? where is the word wave used in atmospheric sciences? It led me to this lady: youtu.be/E1JFiipD6gE?t=24 $\endgroup$ Oct 24 '18 at 3:42
  • $\begingroup$ That really depends on the type of wave. A wave in the atmosphere is more than just what moves back and forth. Waves in the atmosphere are very common (en.wikipedia.org/wiki/Atmospheric_wave for some examples). The frequency of these waves are dependent on their restoring forces and mechanism. For example, Rossby Waves (en.wikipedia.org/wiki/Rossby_wave) have a frequency dependence on mean flow and wavenumber. $\endgroup$ Oct 24 '18 at 15:36
