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
Overlapping clouds (in meteorology, probably duplicatus clouds) are thought to imply eternal happiness [170] and clouds of different colors are said to indicate "multiplied blessings". [ 170 ] Informal cloud watching or cloud gazing is a popular activity involving watching the clouds and looking for shapes in them, a form of pareidolia .
Clouds form as relatively warmer air, carrying moisture, rises within cooler air. The moist air rises, and, as it does so, it cools and some of the water vapor in that rising air condenses . [ 10 ] When the moisture condenses, it releases energy known as latent heat of condensation, which allows the rising packet of air to cool less than the ...
September 19, 2023: Cumulonimbus clouds rise behind wind turbines in Big Spring, Texas. Towering, dense clouds with a flat, anvil-shaped top. Develops from cumulus clouds and can reach great ...
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%.

Depending on the type of clouds, they may vanish as the solar eclipse passes over Texas on Monday. Here's why.
These clouds do not last long, and they tend to change into cirrus because as the water vapor continues to deposit on the ice crystals, they eventually begin to fall, destroying the upward convection. The cloud then dissipates into cirrus. [75] Cirrocumulus clouds come in four species: stratiformis, lenticularis, castellanus, and floccus. [72]
A double-whammy of tropical moisture is expected to bring drenching rainfall to the Gulf Coast this week, following a rather quiet spell in that part of the Atlantic basin. Unlike in previous ...
