Munich Cumulonimbus Cloud
September 11, 2007
The photo above showing a billowing cumulonimbus cloud was captured on the afternoon of May 15, 2007, near Munich, Germany. At first, this immense cloud was barely visible because of the low contrast of the blue sky with the shadowed portion of the cloud. As the contrast increased when the Sun dipped a bit lower in the sky, this powerful looking storm received the attention it was due.
