Definition of inversion for English Language Learners. : a change in the position, order, or relationship of things so that they are the opposite of what they had been.
The condition like this is called an inversion because it is the reverse of a normal air pattern (i.e., warmer air below and cooler air above). The shape of the landscape has an impact on both the formation and intensity of inversion. For instance, over flat terrain inversion gradually intensifies if the surface cools. Over valleys cold air will flow down the slopes and settle under the warm air intensifying the inversion.
