MIRAGES
The first four references are among the most useful standard texts on physical
meteorology. All contain adequately detailed treatment of the general theory of
mirages.

Discusses the rarely seen mirage caused by refraction ol light through an
elevated layer of warm air. The optical effects of such layers have often been
invoked to explain UFO sightings. This article clarifies the severe restrictions
on elevation angle at which such mirages are possible.
