CUMULONIMBUS INCUS at Mykonos, Greece - photo by Sfortis, via Wikipedia; a cumulonimbus cloud which has formed the characteristic flat, anvil-top shape. They can form into supercells resulting in severe storm phenomena such as tornadoes.
The strange cloud formations can be found all over the world. And while they are a bit weird and sometimes scary and foreboding, these clouds remain beautiful. Nature’s sky is painted beautifully by these brush strokes of water vapor…and magic.
