Wave clouds can be a very extraordinary sight. This type of clouds are created as stable air flows over a raised land feature such as a
mountain range, and can form either directly above or in the lee of the feature.
On Christmas morning, Gene Hart of Jonesport, Maine, woke up early to enjoy the sunrise before opening presents, SpaceWeather.com
What he saw may have been the best gift of all. "There was a cloud formation showing a remarkable series of wave shapes," says Hart.
"They were backlit by the rising sun over Moosabec Reach." He snapped this picture of the harbor using a 14-megapixel digital camera:
"I also took some 28x zoom images of the wave structure," says Hart. The close-ups are a must-see.
These clouds, sometimes called "billow clouds," are produced by the Kelvin-Helmholtz instability when horizontal layers of air brush
by one another at different velocities. A better name might be van Gogh clouds: It is widely believed that these waves in the sky
inspired the swirls in van Gogh's masterpiece The Starry Night.
The Starry Night (Dutch: De sterrennacht) is a painting by the Dutch post-impressionist artist Vincent van Gogh.

Phenomenal Rotor Cloud over Pueblo County. The amazing corkscrew appearance was a manifestation of Kelvin-Helmholtz
waves named after Lord Kelvin (1824-1907) and Hermann von Helmholtz (1821-1894).

Fantastic Images Of Man-Made Clouds
A Result Of ATREX Mission
Early in the morning on March 27, 2012, NASA launched 5 small rockets from the Wallops Flight Facility in Virginia.
Each rocket released a chemical tracer that created milky, white clouds at the edge of space. Some of these man- made clouds were truly amazing!
These rockets were part of the anomalous transport rocket experiment or ATREX mission, which is studying high altitude winds.
Fire Clouds Solve An Old Puzzle
Scientists have confirmed that recently identified Pyrocumulonimbus clouds are responsible for unusual atmospheric phenomena.
These eye-catching clouds, which are "born" out of fire have now helped meteorologists to solve an old mystery...
Dangerous Clouds At The Edge Of Space Are Spreading
These mysterious, electric glowing clouds are beautiful to watch, but scientists believe they could be dangerous to our planet.
They were previously only seen over almost exclusively in Earth's polar regions, but they are now also visible in
the skies over the United States and Europe and else where. There is no doubt any more. The clouds at the edge of space are spreading.
