(ĭn-vûr'zhən) Pronunciation Key
A departure from the normal effect of altitude on a meteorological property, especially an atmospheric condition in which the air temperature rises with increasing altitude. ◇ A layer of air that is warmer than the air below it is called an inversion layer. Such a layer traps the surface air in place and prevents dispersion of any pollutants it contains. |
