cloudline

Where clouds begin

Cloudline refers to the visible boundary or horizon where clouds meet the sky or landscape, often observed as a distinct edge separating cloud cover from clear air.

It can describe the lowest altitude at which clouds form over terrain, or the aesthetic line created by clouds against mountains or ocean.

The sun dipped below the cloudline, casting orange light across the valley.

In meteorology and aviation, cloudline helps describe weather conditions and visibility.
