As I mentioned bbc.comPhotograph taken by David Morris while walking off the Corniche coast near Falmouth. The author himself stated that he was stunned after taking it. This phenomenon is considered very rare in this part of the world and at this time of year.
Ship “lift” off the coast of Cornwall. A meteorologist explains the unusual phenomenon
Meteorologist David Breen explained that this illusion is caused by rare weather conditions called temperature inversion. Usually, the higher the layers of air, the lower its temperature. We experience solstice when cold air is close to the sea and warmer above it. Because cold air is denser than warm air, it has a higher global refractive index. An upper mirage is a phenomenon of refraction that occurs several times in successive layers of air, causing light to scatter along a curved line. If the observer is in a place where the light is reflected from the ship, then by extending the rays entering his eye, he will see a simple image of the ship against the sky.
Mirages can create several different types of images. Here, the distant ship appears to be hovering high above its actual location, but sometimes an object below the horizon can become visible, the expert said.
This type of delusion is common in the Arctic. In Great Britain, it may appear very rarely during the winter. In Poland, mirages, also known as mirages, can be seen in the Błędowska desert and in the Silesian Highlands.
