The noun meaning "rising current of relatively warm air" is recorded from 1933.

- Intended or designed in such a way as to help retain body heat.
- Relating to heat.
- A usually columnar mass of warm air that rises in the lower atmosphere because it is less dense than the air around it. Thermals form because the ground surface is heated unevenly by the Sun. The air usually rises until it is in equilibrium with the air surrounding it.
