Cloud street
Cumulus clouds lined up by the wind into long bands.
What it means
They form in certain wind and stability conditions, when thermals organise into rows along the wind. A cloud street is an arrangement of many cumulus rather than one long cloud, and the lift beneath it is often more continuous than between the rows.
Example in context
Under the cloud street I flew straight for ages and hardly had to circle.
