Featured in Both Sides Now – 5/31/09 A cloud is a visible mass of droplets or frozen crystals floating in the atmosphere above the surface of the Earth or another planetary body. A cloud is also a visible mass attracted by gravity, such as masses of material in space called interstellar clouds and nebulae. Clouds are studied in the nephology or cloud physics branch of meteorology. On Earth the condensing substance is typically water vapor, which forms small droplets or ice crystals, typically 0.01 mm in diameter. When surrounded by billions of other droplets or crystals they become visible as clouds. Dense deep clouds exhibit a high reflectance (70% to 95%) throughout the visible range of wavelengths. They thus appear white, at least from the top. Cloud droplets tend to scatter light efficiently, so that the intensity of the solar radiation decreases with depth into the gases, hence the gray or even sometimes dark appearance at the base. Thin clouds may appear to have acquired the color of their environment or background and clouds illuminated by non-white light, such as during sunrise or sunset, may appear colored accordingly. In the near-infrared range, clouds look darker because the water that constitutes the cloud droplets strongly absorbs solar radiation at those wavelengths. Condensation As air parcels cool due to expansion of the rising air mass, water vapor begins to condense on condensation nuclei such as dust, ice and salt. This process forms clouds. Sometimes an elevated portion of a frontal zone forces broad areas of lift, which form cloud decks such as altostratus or cirrostratus. Stratus is a large dark low cloud deck that tends to form when a stable cool air mass is trapped underneath a warm air mass. It can also form due to the lifting of advection fog during breezy conditions. Clouds can also be formed due to lifting over mountains and other topography. Colors The color of a cloud, as seen from the Earth, tells much about what is going on inside the cloud. Clouds form when water vapor is light enough to rise due to becoming warmer than its surrounding. As it rises it cools and the vapor condenses out of the air as micro-droplets. These tiny particles of water are densely packed and sunlight cannot penetrate far into the cloud before it is reflected out, giving a cloud its characteristic white color. As a cloud matures, the droplets may combine to produce larger droplets, which may combine to form droplets large enough to fall as rain. By this process of accumulation, the space between droplets becomes increasingly larger, permitting light to penetrate farther into the cloud. If the cloud is sufficiently large and the droplets within are spaced far enough apart, it may be that a percentage of the light which enters the cloud is not reflected back out before it is absorbed. A simple example of this is being able to see farther in heavy rain than in heavy fog. This process of reflection/absorption is what causes the range of cloud color from white to black. For the same reason, the undersides of large clouds and heavy overcasts can appear as various degrees of gray shades, depending on how much light is being reflected or transmitted back to the observer. / Other colors occur naturally in clouds. Bluish-gray is the result of light scattering within the cloud. In the visible spectrum, blue and green are at the short end of light’s visible wavelengths, while red and yellow are at the long end. The short rays are more easily scattered by water droplets, and the long rays are more likely to be absorbed. The bluish color is evidence that such scattering is being produced by rain-sized droplets in the cloud. A greenish tinge to a cloud is produced when sunlight is scattered by ice. A cumulonimbus cloud emitting green is an imminent sign of heavy rain, hail, strong winds and possible tornadoes. Yellowish clouds are rare but may occur in the late spring through early fall months during forest fire season. The yellow color is due to the presence of smoke. Red, orange and pink clouds occur almost entirely at sunrise/sunset and are the result of the scattering of sunlight by the atmosphere. The clouds do not become that color; they are reflecting long and scattered rays of sunlight, which are predominant at those hours. The effect is much like if one were to shine a red spotlight on a white sheet. In combination with large, mature thunderheads this can produce blood-red clouds.

My house[cochranville pa.] seems to be in the flight path of a major route between phila. pa. , baltimore maryland and washington dc. we get lots of vapor triails from the jets in the setting sun and depending on the wind at altitude they can take on some very interesting shapes mike

This was actually in a set of 4 images. The others are titled “To Set the Sky on Fire” and “Raising Rays”, and were taken minutes apart from the others. / They were taken about 8 to 10 minutes apart, and were taken from Wooling Hill at New Gisborne in the Macedon Ranges on Feb 27th 2009. Another warm night with an incredible sunset. / Needless to say, the fires are still burning. / All monies raised from the sale of this image will go to the RB Phoenix Bushfire Appeal. / ( hdr x3 using PhotoImpact 12 & Dynamic-Photo HDR ) ============================ ====================
/ and it was all Yellow….sunset 11/02/2009 Queensland Australia..as it was going down, the colours of everything went really trippy…almost fluro.Was FABULOUS! :0) Only thing I did to this pic was bring up the brightness abit, and slight contrast. / /

Taken 15/02/2009…yet another beautifully unreal skyscape just on dusk SE qld Australia… / /
The instant I took this photograph puff seemed to be the name. taken at currumbin at sunset gold coast QLD
After a hard rain, as the skies clear a beautiful rainbow appeared! Couldn’t get to my camera quick enough!!!
Whenever I see this I imagine I can see a giant dragon, spitting fire across the sky. Hope you can see the same…
MUCH BETTER VIEWED LARGER Thank you for the comments,views and favouritings they are appreciated. This shot taken at sunrise from my 10th floor vantage point in North Sydney CBD it’s hard but this is my view for breakfast. Fog greets the awakening city and approaching dawn. Equipment : Nikon D300, Handheld, Nikon 18-200mm lens / Technique: 5 bracketted images processed in Photomatix with a slight tidy in Capture NX
I took this shot off the deck in my front yard. The mountains are the Peaks of Otter…a section of the Blue Ridge Mountains in Virginia. This was a really wide rainbow and it is next to a heart shaped cloud. I thought that was pretty cool and not too common to see. Hope you enjoy it. It was awesome in person. / FEATURED IN BACKYARD PHOTOGRAPHY (NO MACROS) / FEATURED IN ALL ABOUT HEARTS / /

Can you see the alien face watching us !!!!!!!!!!!!!!!!!!!!! Nikon D40X / 2008/02/09 16:12:04.2 / Lens: 18-55mm F/3.5-5.6 G / Focal Length: 18mm / Exposure Mode: Programmed Auto* / Metering Mode: Center-Weighted / 1/1250 sec – F/9 / Exposure Comp.: -0.3 EV
These where very strange clouds. They where swirling around above the mountains. As I photographed them a strange feeling came over me, I felt afraid for some reason. I packed up my gear and started down the road. As I drove I noticed a strange light in the clouds above the road. This road is on top of the mountains. I thought it might be a plane but realized a plane wouldn’t be flying that close to the mountains in thick clouds. Beside the light was making a tight circular turn just above the road. I found a place to turn around but couldn’t see the light anymore. I’m convinced this was a sighting…a UFO? I don’t know. A very strange experience to say the least.
The sky and the water appear burnt, plus the sky looks smokey. The vessel is moored on the Manning river, downstream from Taree, at Cundletown, NSW, Australia. Taken after sunset. Nikon D40x, handheld on auto. As is. No post editing. Untouched.
Stormhead cloud
Well me and my mum went to Palmerston North before i was shipped down here, we always stop off at the side of the road in one particular spot, Mt Ruapehu had its first now and i was snap happy with the camera, i darkened it because there is nothing but a table and a road below the clouds. Enjoy!
A group dedicated to images of clouds that show their magnificence, or stir the imagination. This site is for cloud images that display clouds as the main theme of the picture. This group is for those who enjoy clouds from both sides.
“Both Sides Now” by Joni Mitchell
Rows and floes of angel hair
And ice cream castles in the air
And feather canyons evrywhere
I’ve looked at clouds that way
But now they only block the sun
They rain and snow on evryone
So many things I would have done
But clouds got in my way
Ive looked at clouds from both sides now
From up and down, and still somehow
Its cloud illusions I recall
I really don’t know clouds at all
