Lenticular clouds are stationary clouds that form mostly in the troposphere, typically in parallel alignment to the wind direction. These lens-shaped orographic wave clouds form when the air is stable and winds blow across hills and mountains from the same or similar direction at different heights ...

Altocumulus Standing Lenticular Clouds: When sufficient moisture is present above mountain-top level, ACSL clouds develop within the crest of these mountain waves where the air is rising. ACSL clouds are continually developing and dissipating in the vicinity of the wave's crest and immediately dow...

A rainbow cloud can occur because of something called cloud iridescence. It usually happens in altocumulus, cirrocumulus, lenticular and cirrus clouds. Iridescent clouds happen because of diffraction – a phenomenon that occurs when small water droplets or small ice crystals scatter the sun's light.

I recreated Vincent van Gogh's "Starry Night" from just over 7,000 dominos. The second attempt took about 11 hours total to build. The first attempt failed, when I dropped a screw from the camera rig onto it. I was able to improve the swirling clouds better in the second attempt as a result though....

For the next two years starting tonight, San Francisco's Bay Bridge will host artist Leo Villareal's magnificent installation "The Bay Lights", a shimmering LED sculpture that draws its inspiration from the bridge's surroundings - boats, waves, clouds, the city itself.

Calbuco, the Chilean volcano which erupted violently twice mid April, 2015 for the first time in 40 years, spewed out a plume of ash more than six miles high and blanketed parts of Chile and Argentina. More than 4,000 were evacuated but thankfully no deaths or injuries have been reported. Rodrigo B...

An incredible photographic journey capturing amazing lightning displays around the world. Lightning is a massive electrostatic discharge between the electrically charged regions within clouds or between a cloud and the surface of a planet. The charged regions within the atmosphere temporarily equali...
