Detecting Gravity Waves: Seeking Answers

AI Thread Summary
Gravity waves are distinct from gravitational waves and are primarily related to fluid dynamics in the atmosphere and ocean. Detection methods for gravity waves often involve visual inspection and can include measuring vertical movements using specialized floats. The discussion highlights the importance of differentiating between gravity waves and gravitational waves, emphasizing their relevance in meteorology. A suggested method for quantifying gravity waves involves using a float on a shaft to track vertical movements and applying Fourier transforms to analyze the data. Understanding these detection techniques is crucial for studying atmospheric phenomena.

HI,
Can someone please tell me how gravity waves are detected. Please note that I am talking about gravity waves "not" gravitational waves they are two different things. Any help is appreciated.
Thanks
 
Physics news on Phys.org
in what medium?
 
Both atmosphere and the ocean but more on atmosphere. Thanks.

Please explain what you think the difference is.
 
Gravity waves has something to do with the sky (meteorology) and gravitational is something to do with astronomy.
 
Gravity waves is a fluid dynamics thing. I'll rummage through my applied maths notes if I have the time later.
 
yes, but how are they detected? please help. any help is awesome. thanks

I don't think that's what the OP is referring to.

Pretty sure it is, given he mentions atmosphere and ocean, which are the two canonical examples of gravity waves, and is talking about meteorology, not general relativity. Everyone seems to be confusing gravity waves for gravitational waves, and I think the op has made it abundantly clear that he is referring to the former.

Having re-read the posts I see that now. My bad.

The wikipedia page does not answer my questio, I have already been there. I need to know how they detect these gravity waves. Please help, thanks.

If I wanted to measure and quantify them, I'd make a float like a fishing bob, on a shaft so it can only move vertically. Measure the position of the bob over time, and then use a Fourier transform on the list of numbers to identify the mixture of waves present.
