A superior mirage is an optical phenomenon that occurs when light rays bend due to temperature differences in the atmosphere. This bending, or refraction, happens when cold air lies close to the surface and warmer air is above it. As a result, objects below the horizon can appear elevated, creating distorted images of ships, land, or even the sky. These mirages are most commonly seen in polar regions, where the temperature contrasts are significant. They can also occur over large bodies of water, such as the Great Lakes or the Arctic Ocean. Superior mirages can create stunning visual effects, making distant objects seem closer or even inverted.
