Review Of Mirage On Road Ideas. Mirages occur when there is a rapid shift in air density in the atmosphere — when the air at one level is a lot hotter than the air at an adjoining level (check out this page to find out why hot air is less dense than cold air). The case of a road looking wet is known as an inferior mirage.

Mirages occur when there is a rapid shift in air density in the atmosphere — when the air at one level is a lot hotter than the air at an adjoining level (check out this page to find out why hot air is less dense than cold air). When driving around at this time of year and looking ahead, you see what looks like a reflection of water on the road. Mirages are caused by atmospheric refraction and are predominantly observed in settings where there are drastic variations in the atmospheric temperature, such as over cold water bodies or deserts (mirage meaning).
