rainbow clouds, circumhorizontal arc and sundogs
this rare meteorological phenomenon happened on yesterday (AM08:08:20, 2007/7/19) in the sky of Taipei.
i used a 70-200mm VR with CPL filter to shoot from my office's balcony.
please correct me, if the title or description are worng.
to view all photos about clouds 雲.
ps:
Sundogs, also known as mock suns or "parhelia", are a pair of brightly colored spots, one on either side of the sun.
A circumhorizontal arc is an optical phenomenon similar in appearance to a rainbow, caused by the refraction of light through the ice crystals in cirrus clouds. It occurs only when the sun is high in the sky, at least 58° above the horizon. The phenomenon is quite rare, since the ice crystals must be aligned horizontally (instead of the more typical vertical alignment) to reflect. (Wikipedia)
