cold-air pool

A topographic depression, such as a valley or basin, filled with cold air.

The cold air is heavy, and settles to the bottom of the depression. This air can remain stagnant, trapped by the surrounding higher terrain, resulting in long periods of poor air quality and fog, depending on the sources of pollution and amount of moisture in the air, respectively.
