    OK, the air higher up in the atmosphere is warmer and less dense. When a packet of air is forced to rise above its natural level (dictated by its temperature), say by wind blowing it over a mountain, it will surrounded by air that`s less dense than it, and will want to sink just like a rock that`s denser than the surrounding water. So it accelerates downwards, but doesn`t stop moving once it reaches the right level again. It goes further down (overshoot) and gets forced back up by the more dense air. This is called simple harmonic motion, and if the wind is blowing steadily you end up with a pretty sine wave like this. Science rules :) More info here.

    It just looks un-natural and bizare, and brings to mind an obvious wave. the sky moving would bring to mind gravity fluxuations. He didn`t actually think it was gravity waves you arm chair physicists. if you can understand that maybe you can understand an offhand discription.

    over such a short time?
    amazing!
    i saw something like that before, 2 years ago, there was a very high breeze and the clouds surface for miles and miles was rippled.. it was amazing... it looked like one of those soundproofed walls.
    i haven`t seen a cloud in three days though
    gotta love summer :)

    gravity wave is the correct name for it. the definition of a gravity wave is a vertically oscillating wave in which gravity is the restoring force. The name is a bit misleading, they should actually be referred to as buoyancy waves, because as stated earlier, buoyancy due to temperature differences in the restoring force.
    p.s. - anyone in the 13-17 age range most likely doesnt know enough about physics to be complaining about other peoples understanding of it.

    Clouds can do amazing stuff, watch the cirrus long enough and you can see faces, and animals, just like in the fluffy cumulus. (Except cirrus is cooler.)

    (P.S. I think those were Cumulonimbus, because those are the ones that carry water (I believe, or maybe it was nimbostratus (been a while since I studied a cloud chart)) and you can see rain dripping off of the top of the screen.)

    dumaspere`s explanation is prolly mostly right. I just don`t know if simple harmonic motion applies to clouds, I`ve always known it to apply to springs, but wasn`t sure about the sky.

    As amazing as this is, I`d be paranoid if I saw the clouds moving like that in real time. Especially after that one day where the clouds rolled in and started pouring in seconds when I was golfing. There was this big concentration of swirling, dark grey clouds when I was driving home, reminiscent of horror movies of sorts where this one place turns out to be a native burial ground. Anyways, still awesome: 4.

    serfis, simple harmonic motion occurs when the acceleration of a body is always towards its natural "rest" position, and when the acceleration is directly proportional to the distance it is away from this position so a = k(-x) where a is a constant. The relationship crops up so often everywhere in nature that they started using the term SHM. (I am assuming that whatever the relationship between height and density of air, the amplitude of cloud oscillation is small enough compared to the height above the ground, that the relationship is approximately linear over that region, giving SHM.)
