A superior mirage occurs when there is a pronounced inversion near the surface, and normally at sea.

Probably the most credible explanation is a superior mirage or Fata Morgana seen at sea.

A superior mirage can be right-side up or upside down, depending on the distance of the true object and the temperature gradient.

A "Fata Morgana" is a complex superior mirage whose appearance can change quickly and dramatically.

Assuming that Morrell did not invent the experience, a possible explanation is that he witnessed a superior mirage.

Superior mirages also occur at more moderate latitudes, although in those cases they are weaker and tend to be less smooth and stable.

A mirage was still present at that point, but it was not as complex as few hours before sunset: the mirage was no longer a Fata Morgana, but instead had become a simple superior mirage.

Superior mirages are in general less common than inferior mirages, but, when they do occur, they tend to be more stable, as cold air has no tendency to move up and warm air has no tendency to move down.

Mirages can be categorized as "inferior" (meaning lower), "superior" (meaning higher) and "Fata Morgana", one kind of superior mirage consisting of a series of unusually elaborate, vertically stacked images, which form one rapidly changing mirage.
