A Circumhorizontal Arc Over Ohio

Why would clouds seem to be reasonably about a colours? The motive right here is that ice crystals in distant cirrus clouds are acting fancy minute floating prisms. Most regularly identified as a hearth rainbow for its flame-fancy look, a circumhorizon arc lies parallel to the horizon. For a circumhorizontal arc to be seen, the Sun must be no longer lower than 58 degrees high in a sky the assign cirrus clouds are unique. Furthermore, the reasonably about a, flat, hexagonal ice-crystals that form the cirrus cloud must be aligned horizontally to correctly refract sunlight hours in a collectively the same scheme. As a result of this truth, circumhorizontal arcs are reasonably habitual to witness. This circumhorizon hiss used to be photographed thru a polarized lens above Dublin, Ohio in 2009.
