would you please clarify how you ID'd this? I looked at http://www.clouds-online.com/cloud_atlas/stratocumulus/stratocumulus.htm and see Stratocumulus undulatus looks like these clouds, but I wonder how you tell it would help clarify the answer if you shared how you tell these apart from the OP's idea Asperatus undulatus.

<p>I would like to know if anybody knows the name of this cloud formation.</p>

<p>The picture was taken in Bern Switzerland, just before a cold front moved in. I am thinking about roll clouds or Asperatus undulatus... It was wavy but the clouds formed rolls.</p>

I would like to know if anybody knows the name of this cloud formation.

The picture was taken in Bern Switzerland, just before a cold front moved in. I am thinking about roll clouds or Asperatus undulatus... It was wavy but the clouds formed rolls.
