  2. Cloud albedo - Wikipedia

    en.wikipedia.org/wiki/Cloud_albedo

    Higher liquid water and ice content in a cloud increases its albedo, which is the dominant factor in determining the cloud's reflectivity. [ 6 ] [ 7 ] The change in albedo is greater for clouds with less water content to start with and larger clouds begin to receive diminishing returns with increased content.

  3. Cloud physics - Wikipedia

    en.wikipedia.org/wiki/Cloud_physics

    the cloud IR emissivity, with values between 0 and 1, with a global average around 0.7; the effective cloud amount, the cloud amount weighted by the cloud IR emissivity, with a global average of 0.5; the cloud (visible) optical depth varies within a range of 4 and 10. the cloud water path for the liquid and solid (ice) phases of the cloud particles

  4. Hurricane dynamics and cloud microphysics - Wikipedia

    en.wikipedia.org/wiki/Hurricane_dynamics_and...

    Hurricanes are mixed-phase clouds, meaning that liquid and solid water (ice) are both present in the cloud. Typically, liquid water dominates at altitudes lower than the freezing level and solid water at altitudes where the temperature is colder than -40 °C. Between 0 °C and -40 °C water can exists in both phases simultaneously.

  5. Storm clouds make great pictures, but what do they mean - AOL

    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 ...

  6. Cloud - Wikipedia

    en.wikipedia.org/wiki/Cloud

    In meteorology, a cloud is an aerosol consisting of a visible mass of miniature liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body or similar space. [1] Water or various other chemicals may compose the droplets and crystals.

    Growing up to 5,000 meters above sea level, they are the highest-altitude trees in the world and are known to absorb and retain water from clouds and the Andes’ melting glaciers. Slowly, they ...

  8. Cloud feedback - Wikipedia

    en.wikipedia.org/wiki/Cloud_feedback

    Under dry, cloud-free conditions, water vapor in atmosphere contributes 67% of the greenhouse effect on Earth. When there is enough moisture to form typical cloud cover, the greenhouse effect from "free" water vapor goes down to 50%, but water vapor which is now inside the clouds amounts to 25%, and the net greenhouse effect is at 75%. [21]

  9. Outgoing longwave radiation - Wikipedia

    en.wikipedia.org/wiki/Outgoing_longwave_radiation

    Assuming no cloud cover, most of the surface emissions that reach space do so through the atmospheric window. The atmospheric window is a region of the electromagnetic wavelength spectrum between 8 and 11 μm where the atmosphere does not absorb longwave radiation (except for the ozone band between 9.6 and 9.8 μm).
