Report shows gravity waves in clouds(?)

In summary: The article does a good job of explaining what these waves are and how they are generated. They are not identical to gravitational waves, which are disturbances in the curvature of spacetime created by massive acceleration.

Report shows gravity waves in clouds
https://www.sciencealert.com/a-weat...rely-seen-gravity-waves-in-earth-s-atmosphere
This shows satellite images of what are being called gravity waves in clouds. There is an explanation of what happens in the example, using a timelapse 'movie'

Is this a nomen confusum - the same name for completely different phenomena? i.e., not LIGO. Could also be bad science reporting...

If it is it an evil twin name it definitely succeeded in confusing me. And my google searches.

There is a difference between gravity waves (weather) and gravitational waves(LIGO) :smile:

Waves on water are often referred to as gravity waves to distinguish them from the surface waves on solids.

Not bad reporting. They explicitly explain the difference in the article.

Well, thanks to weather satellites, now you can take a mighty gawk at atmospheric gravity waves that rippled out over Western Australia last week.

Not to be confused with gravitational waves, which are disturbances in the curvature of spacetime created by massive acceleration, gravity waves, also known as buoyancy waves, are a physical phenomenon where waves are generated in any fluid medium, such as waves at the beach, or ripples in a glass of water.

So any bad attaches to scientists who coined these confusing meanings, not the reporter.

You don't have to go to exotic places like OZ to see them. I remember standing near the brow of a mountain in the Pyrenees (at about 2.5km altitude) and watching those waves on top of stratus clouds rolling towards me and 'breaking on the shore" at my feet (slo mo). I was delirious about it but there was no one to discuss it with at the time. At least the Astronauts have someone to share it with when they see them.

Great answers. Thanks.

@anorlunda : I guess that was an equivalent experience to your blue water ones.

And that articles opening statement is garbage ….
Rarely Seen Gravity Waves Captured Rippling in Earth's Atmosphere

The atmosphere is fluid. This means it's subject to fluid dynamics, such as circulation, currents, and, yes, gravity waves. The atmosphere is always in motion, so these phenomena happen all the time; but actually seeing them is another matter.
They are not rare... in fact pretty common

1. What are gravity waves in clouds?

Gravity waves in clouds are large-scale disturbances that occur in the Earth's atmosphere and are caused by the interaction of air with the force of gravity. These waves can be seen as ripples or patterns in the clouds and can travel long distances.

2. How do scientists detect gravity waves in clouds?

Scientists use various instruments, such as satellites and weather balloons, to detect and measure gravity waves in clouds. These instruments can track changes in air pressure, temperature, and wind speed to identify the presence of gravity waves.

3. What causes gravity waves to form in clouds?

Gravity waves in clouds are primarily caused by disturbances in the atmosphere, such as strong winds or changes in temperature. These disturbances can create variations in air density, which then interact with the force of gravity to form the waves.

4. What is the significance of detecting gravity waves in clouds?

Detecting and studying gravity waves in clouds can help scientists better understand the dynamics of the Earth's atmosphere and how it affects weather patterns. It can also provide valuable information for predicting and monitoring severe weather events.

5. Can gravity waves in clouds be harmful to humans?

Gravity waves in clouds are not harmful to humans as they occur high in the Earth's atmosphere and do not directly affect us on the ground. However, they can have indirect effects on weather patterns, which may impact human activities and infrastructure.
