What is a Cloud Street?

Clouds can form some imaginative formations, but a new one on me is a cloud street. A cloud street, or more technically a horizontal convective roll, is actually a long row of cumulus clouds that is aligned parallel to the direction of the wind. They usually form straight rows, but when the wind hits an obstacle,
