A mirage is the multiple imaging of objects near the
horizon
by
atmospheric refraction
in which erect and inverted images always alternate. However, some images are frequently so distorted as to be unrecognizable, leaving only a single recognizable inverted image or two erect ones. As with
green flash
phenomena, there are several kinds.
The term "mirage" should not be applied to displays of
atmospheric refraction
such as looming and towering that merely distort the ordinary erect image.
