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 that are normally below the horizon can appear elevated, creating the illusion of seeing distant landscapes or even ships floating in the air. These mirages are most commonly observed 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 are a fascinating example of how atmospheric conditions can alter our perception of reality.
