Fleagle, Robert G. The optical measnreme11t of lapse rate. B.llletin of the
American Meteorological Society, 31(2), February 1950: 51- 55,
The author develops a method to measure the change of temperature with
height by optically measurL1g the apparent change in elevation of a light source.
Nomograms are provided which show the difference between ?.pparent and true
elevations as a function of lapse rate and length of optical path.
Gordon, J. H. Mirages. Washington, D. C., Smithsonian Institution Publication
4398, 1959, published 1960.
A non-technical article that describes mirage formation as dependmg on a lens
of air similar in function to lenses in cameras.
Haug, Odd. On the theory of superior mirages. Meteorologiske Annaler, Oslo,
3(12), 1953: 295-310.
A full discussion of light passing through a strong inversion.
ten Kate, H. Luchtspiegelii.gen. Hemel en Dampkring, 49(5), 1951: 91-94.
Clear explanations, with good illustrations, of the th-eory of mirages.
Kohl, G. ErkUlrung einer luftspiegelung nach oben aus radiosondierungen.
Zeitschrift fur Meteo,·ologie, 6(11), November 1952: 344-348.
A mirage in Fichtelgebirge is explained quantitatively from radiosonde data.
Minnaert, M. Light and colour in the open air. New York, Dover Publication,
1954.
A superb example of non-technical exposition covering not only mirages but
also nearly every other aspect of visual and optical phenomena in the sky and
the landscape, from rainbows to the spoke-patterns in bicycle wheels.

IdS°jar:l:s, 58(3), May-June 1954: g3-153.
Classical mirage theory on!y handles the formation of three images. The
author proposes to handle more than three images by considering reflections
from wave surfaces on inversions.

developed in great cletail and a number of striking cases are carefully examined.
