Mirage
(gcide) | Mirage \Mi`rage"\, n. [F., fr. mirer to look at carefully, to
aim, se mirer to look at one's self in a glass, to reflect,
to be reflected, LL. mirare to look at. See Mirror.]
An inverted image due to atmospheric refraction. Multiple
images, alternately erect and inverted, are produced by large
changes in lapse rate with height. Inferior mirages (below
eye level) are seen over paving, water, sand, snow, sunlit
walls, freezing lakes and rivers, and other smooth surfaces
warmer than the adjacent air. Objects appear as if reflected
by a sheet of water, or may seem suspended in the air above a
narrow strip of miraged sky; or the shadowed undersides of
vehicles and leaves appear as dark patches that recede as an
observer approaches them. Superior mirages are due to thermal
inversions above colder surfaces, and produce inverted images
above the horizontal. The Fata Morgana is a superior mirage
characterized by a striated zone of extreme vertical
elongation, which may resemble columnar basalt. Other types
of mirage also occur; all are refraction phenomena with
inverted images.
[A. T. Young]
By the mirage uplifted the land floats vague in the
ether,
Ships and the shadows of ships hang in the motionless
air. --Longfellow.
