Thermal ceiling

The height to which rising warm air climbs before thermals die out.

Also known as

  • top of lift standard term

Terms and slang labels apply to this language. Usage may differ in other languages.

What it means

Pilots often use it loosely as another word for cloudbase, but the two differ. On a cumulus day cloudbase usually caps the climb; on a blue day an inversion sets the ceiling.

Example in context

The thermal ceiling was low today, so I hardly got above the ridge.
