    Inferior Mirage of Amerigo Vespucci

      Summary Author:  Marcella Giulia Pace   
      
      Shown above is a sailing ship, the  Amerigo Vespucci, that was   
      miraged on the horizon of the Ragusa Coast of Sicily, Italy.  This   
      photo was taken from the seafront of  Marina di Ragusa (Sicily) at a   
      height of about 9 m, and therefore the visible horizon was about 10 km   
      distant. Thus, the Earth's curvature actually conceals most of the   
      ship. Layers of warm air, beneath layers of cooler air generated this   
       inferior mirage, in which the visible parts of the ship are flipped   
      downward. This “overturning” made the ship's bowsprit appear like a   
      great, open mouth advancing towards the sea.   
      
      Note that the  "Amerigo Vespucci", an Italian military school ship,   
      dates from 1931.  Click here to see a video of this mirage. Photo   
      taken on August 28, 2022.
