Aviation Glossary - Temperature Inversion

At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official, and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can find that which best applies to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including our FAA written test prep and FAA practical test prep software and apps. If you like this glossary, you'll love them with their polished learning environments and world's best and clearest content (please do give them a try.).

Temperature Inversion

A condition in the atmosphere in which a region of cool air is trapped beneath warmer air.

An increase in temperature with height-a reversal of the normal decrease with height in the troposphere; may also be applied to other meteorological properties.

source: FAA Aviation Weather for Pilots (AC 00-6A)

An increase in temperature with altitude.

(surface-based or elevated) : a layer of the atmosphere in which air temperature increases with height. When the layer's base is at the surface, the layer is called a surface-based temperature inversion; when the base of the layer is above the surface, the layer is called an elevated temperature inversion.
