An occurrence of altocumulus and cirrocumulus cloud iridescence Sunset reflecting shades of pink onto grey stratocumulus clouds. The color of a cloud, as seen from the Earth, tells much about what is going on inside the cloud. Dense deep tropospheric clouds exhibit a high reflectance (70% to 95%) throughout the visible spectrum.
Noctilucent clouds (NLCs), or night shining clouds, [1] are tenuous cloud-like phenomena in the upper atmosphere of Earth. When viewed from space, they are called polar mesospheric clouds (PMCs) , detectable as a diffuse scattering layer of water ice crystals near the summer polar mesopause .
Cloud iridescence or irisation is a colorful optical phenomenon that occurs in a cloud and appears in the general proximity of the Sun or Moon. The colors resemble those seen in soap bubbles and oil on a water surface.
Mammatus clouds filled the sky over Bucks County on Sunday night, June 30, 2024, giving a treat of orange and pink fluffy clouds and filling social media with the spectacular sky.
Skyglow is significantly amplified by the presence of snow, and within and near urban areas when clouds are present. [7] In remote areas, snow brightens the sky, but clouds make the sky darker. In remote areas on moonless nights clouds appear dark against the sky. In or near developed areas skyglow is strongly enhanced by clouds.
Paranal Observatory nights. [3] The concept of noctcaelador tackles the aesthetic perception of the night sky. [4]Depending on local sky cloud cover, pollution, humidity, and light pollution levels, the stars visible to the unaided naked eye appear as hundreds, thousands or tens of thousands of white pinpoints of light in an otherwise near black sky together with some faint nebulae or clouds ...
Whether hues of green, red, blue and even pink dance about in the sky depends on the altitude where the collisions occur, as well as the composition and density of the atmosphere at the time.
A mackerel sky is a term for clouds made up of rows of cirrocumulus or altocumulus clouds displaying an undulating, rippling pattern similar in appearance to fish scales; [1] [2] this is caused by high altitude atmospheric waves. [3]
