    A typical example for a sunset within a strong inversion is shown on this page
    http://www.atoptics.co.uk/atoptics/gfim13.htm
    Typical for it is the sun reaching a rectangular shape. I usually
    didn't notice it when looking directly at it, but afterwards on the
    photo. Also typical is the bright line which remains at the horizon
    may be for 10, 20 or more seconds and which gives the impression that
    the sunset is delayed.
    
    The Omega-Sun or inferior-mirages appear typical in autumn when the
    sea water has been warmed during summer and the atmosphere becomes
    colder. The opposite, the Inversion-Sun or mock-mirages appear
    typically during spring.
