Dense deep tropospheric clouds exhibit a high reflectance (70% to 95%) throughout the visible spectrum. 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, especially when viewed from the top.

Low, ragged clouds that appear beneath the main cloud base. Formed from moist air lifted by outflow winds from a storm. Often mistaken for tornadoes, but they are typically harmless, indicating ...

Clouds form when the dew point temperature of water is reached in the presence of condensation nuclei in the troposphere. The atmosphere is a dynamic system, and the local conditions of turbulence, uplift, and other parameters give rise to many types of clouds. Various types of cloud occur frequently enough to have been categorized.
A homogenitus, anthropogenic or artificial cloud is a cloud induced by human activity. Although most clouds covering the sky have a purely natural origin, since the beginning of the Industrial Revolution , the use of fossil fuels and water vapor and other gases emitted by nuclear, thermal and geothermal power plants yield significant ...
If clouds do obscure the view, there are many places to watch the total solar eclipse online.
Neptune has long been known to have white clouds circling it, but images of the furthest planet in the solar system have shown this changing over time - the most recent image, taken by the Hubble ...
This is regarded as proof that humans have been creating and modifying clouds for generations through the combustion of fossil fuels. [citation needed] Although ship tracks can sometimes be visible, researchers usually scan the near-infrared light coming off the clouds. At this wavelength many ship tracks appear as bright lines that can be ...
