View Full Version : OT. But had to share this link. Time Lapse of a 'Gravity Wave'. Amazing video.

I was just blown away by this video of a natural phenomenon that I had never heard of.

Check it out.

Cheers, MP.

Seen this a couple of times live here under the Alps: they present an obstacle high enough (2-3km) with plains below them (which are also imperative for the "gravity waves" to occur). You still have to be very lucky to see them.

Name "gravity waves" is misleading tho, as gravity has as much to do with this waves as it does with for example sea waves.

This has more to do with fluid dynamincs than gravity. Gravitational waves are well beyond detection... even if caused by celestial events.

This has more to do with the properties of the air than with gravity I'd say, but still a very nice movie!

It looks cool,thx for sharing.

But I think it's meteorological not physical.
It looks like an area of different dewpoint(where clouds form-basically)is shifting with winds,because notice the front arriving at the end,hence the atmospheric turbulence.

Listed it as Gravity Wave as that was it's title....ah well we live and learn...still looks amazing!

Gravity Waves (http://en.wikipedia.org/wiki/Gravity_Wave) not Gravitational Waves (http://en.wikipedia.org/wiki/Gravitational_radiation)
