The Weeping Clouds
The hot day ended with thunderstorms and a spectacular light and cloud formations unknown to me so far.
Mammatus clouds are most often seen on the back of a heavy shower or thunderstorm cloud, less often in other clouds. In most cases they are smooth with evenly layered gliding structures and hang down bag-like on the underside of the ambos cloud. Sometimes only a few mammoth clouds are visible, in other cases half of the sky is covered with them. The name comes from the Latin "mamma" for breast and means as much as breast-like.
