This is a skyscape image. The whole horizon from North to South was connected with these unusually formed clouds. Does anyone have an idea of what type of cloud this is? As I've read a few books on them and Ican't find one that looks quite like this.
I belive this is an example of altocumulus undulatus. Middle troposphere with wavy herring bone like shape. You'll find these are between 6500 and 17000 ft and are formed with the steady rise of a large air mass, with some wind-shear (giving light turbulance usually) at cloud height. Theycpold be a sign of an approachig warm front and can lead to precipitation if the cloud thickens enough.
