A Rainbow Pileus Cloud over Zimbabwe
Explanation: Yes, but how many dark clouds have a multicolored lining? Pictured, behind this darker cloud, is a
pileus iridescent cloud, a group of water droplets that have a uniformly similar size and
so together diffract different colors of sunlight by different amounts. The
above image was taken just before sunset when it was noticed by chance by a photographer in
Murambi East, near
Odzi Valley and the
Mtanda Range of
Zimbabwe. Also captured were unusual cloud ripples above the
pileus cloud. The formation of a rare pileus cloud capping a common
cumulus cloud is an indication that the lower cloud is
expanding upward and might well develop into a
storm. In this case, however, only a few minutes after the
colorful cloud was noticed, it
disappeared.
