For science and weather lovers especially, the internet is a fabulous resource for experiencing the world in ways one doesn’t ordinarily get to do. The video below shows the cloud deck in the sky behaving just like waves on a lake, the ordinary daily cycle, that because of the time scale, we don’t ordinarily “see”. Gravity waves are the waves in a fluid that occur as the fluid tries to seek a uniform plane – ie, gravity pulls the peaks down. Its the same effect that occurs on a lake after the wind has stopped blowing, or when you throw a rock into a pond.

Our atmosphere behaves the same way as its pushed around under the many things that influence it.

This video was picked up from WUWT in a thread about cloud phenomena. Have a look and follow some of the commenter’s links. Wonder beckons.
