• Brightness of the sun is based upon temperature and a sunspot's temperature is lower than the surrounding surface of the sun. Noctilucent clouds (NLCs) are the highest and most enigmatic of our planet's cloud forms. Yes, I would agree with you there that the water must freeze directly on the nuclei, no liquid phase involved. On some days, the clouds are visible at middle latitudes. We see that sunlight's color due to Mei scattering which scatters all remaining wavelength colors equally. What color are most street lights? 252 216 22. JetStream, Comments?

Cirrus, the highest of the common clouds, form starting at around 20,000 feet (6 km) near the top of the troposphere when water condenses as ice crystals on dust, salt, soot, and other aerosols including synthetic pollutants. The image above shows a satellite view of noctilucent or “night shining” clouds on June 12, 2019. Unlike Rayleigh scattering, where the light waves are much smaller than the gases in the atmosphere, the individual water droplets that make up a cloud are of similar size to the wavelength of sunlight. Clear night ahead? Thank you for the article about this fascinating elusive phenomena.

The contrast in brightness between the two is what causes sunspots appear dark. Moonlit night in Nevada, USA with starry night sky, Landscape with a wooden house with light from the window in a winter night. From many mid-latitude locations the best time to look for them is between 9:30 p.m. and 11 p.m. The Color Of The Clouds At Night, a song by Jeff Zentner on Spotify. Called noctilucent — literally, "night shining" — clouds they unfurl across the northern sky in electric-blue bands, undulating ripples, and fibrous tendrils long after sunset when other clouds have ceased to glow. A more common reason is the contrast between the background (blue sky or additional clouds) and foreground cloud overwhelms our vision. The color of a cloud depends primarily upon the color of the light it receives. The instrument measures albedo, or the amount of light reflected back to space by the high-altitude clouds. Noctilucent clouds float high enough in the atmosphere to capture a little bit of stray sunlight even after the Sun has set below them. Across northern Europe and Canada night-shining clouds can cover large swaths of the northern sky, but from mid-latitudes like those in the U.S. you'll need a good northern horizon to spot them. Thunderstorm Sea Clouds. The Curiosity Mars rover acquired an image of the clouds in the skies over Mars on May 17, 2019, or sol 2,410 of the mission. Ultraviolet (UV) light from the Sun heats and puffs up Earth's outer atmosphere during solar maximum, but a decrease in UV at minimum leads to atmospheric cooling. Maybe all children love to play the game of spotting animals in the shapes of the clouds. Ashley Cooper / Getty Images. Close Sort by: Best Match.
