An inferior mirage is a mirage of an object visible below that object. Usually the mirage is mirrored upside-down. On hot sunny days, such mirages can be seen over flat land, such as a plowed field. They are also common in the desert, and cause the infamous oase which is not there. The mirage causes the sky to be reflected on the soil, and so it looks as if there is a reflecting water surface.
