More than a century after the sinking of the Titanic, scientists and historians are still trying to understand what happened on that fateful night. New hypotheses, including the one that declares a Fata Morgana type mirage was involved in both the collision with the iceberg and the failed communications between the Titanic and the Californian, are being introduced on a regular basis. This article is the first in a four‐part series that examines the mirage theory of the Titanic disaster. In this part, a few ways in which a temperature inversion (which is required for a mirage to form) could have developed at the site of the disaster at the time of the collision and subsequent sinking are explored. A high‐pressure cell, an icy river of melt‐water and the Gulf Stream are all examined as factors that could have contributed to the formation of an inversion. It is demonstrated that the development of a steep temperature inversion at the wreck site, though rather unlikely, cannot be excluded completely.

“…Ducted mirages of terrestrial objects are reported in many places around the world (Young and Frappa, ), while ducted mirages of astronomical objects, such as the sun, are much rarer. The author is aware of only two publications describing the Novaya Zemlya effect mirage outside polar regions: one off Cape Town, and one off Finland (see Young’s Annotated bibliography of mirages, green flashes, atmospheric refraction, etc .…”

Sunset mirages involving ducts

Sunset mirages are often observed in coastal California. Cold ocean currents and warm air from inland create great conditions for temperature inversions, prerequisite required for producing mirages. Most sunset mirages seen in California are so called mock mirages. Inferior mirages are also common during winter time. On a rare occasions California sky watchers are treated by some special mirages that involve ducting, including Novaya Zemlya effect sunsets, blank strip sunsets and others.

“…In most situations, when a fog arrives, the mirage leaves, but sometimes the mirage stays just a little bit longer to play the same joke with the fog as it does with everything else (Figure 2). Maltin (2012) has suggested that a very special mirage might have been present at the site of the Titanic disaster -a Fata Morgana of the sea surface ( Figure 4), also known as a 'Fata Brumosa' (Young and Frappa, 2017).…”
