Ghost ship (Superior mirage)


A mirage can be also observed at the sea in the vicinity of the geographical pole.

In this area, the upper layers of air are hot compared to the lower layers of the air.
Rays of the ship are refracted away from the normal until total internal refraction occurs. After that, the rays of light are refracted following a curve bending towards the normal until they reach the eyes of the observer.
The image is inverted and appears in the sky.
