inferior mirage

A spurious image of an object formed below the true position of that object by abnormal refraction conditions along the line of sight; one of the most common of all types of mirages. The requirement for the appearance of an inferior mirage is a very large lapse rate of temperature in the layer of air containing the line of sight from the observer to the object.
