Artificially produced space charge was released into the atmosphere near the ground during convection. Measurements showed that clouds that form in the electrically modified region exhibited significantly larger potential gradient perturbations than otherwise similar clouds forming nearby. When the charge ...
Revealed in the citizen scientists' cloud maps are populations of carbon dioxide ice clouds at high altitudes, clouds that form near the poles of the Red Planet, and also water-ice clouds. These latter clouds are believed to form during particular dusty seasons on Mars, particularly during sprin...
Cirrus clouds are high-level clouds composed of ice crystals that form at high altitudes. They have a hair-like, wispy appearance and often indicate that a change in the weather is coming. These delicate clouds can be seen near the sun or moon, sometimes producing a halo effect. They often...
If you’ve ever looked up and wondered, “What type of cloud is that?” this piece is for the budding nephologist (person who studies clouds) in you. By observing clouds, you can predict the incoming weather! See our Guide to Clouds with pictures of common cloud types in the sky and ...
Cumulonimbus are flat-topped. Near the ground, they have clear edges. Higher up, they look wispy. 那些积云会越来越大了吗?它们也在更高吗?如果是的话,拿把你的伞。 积雨云正在形成。它们也被称为风暴云。这些云彩意味着大...
The guard said, "You’ve just missed one. A train goes every hour. The next one is at ten o’clock.: "That’s all right," they said, "We’ll go and have a drink." So off they went to a bar (酒吧间). A minute or two after ten o’clock they came running and asked the ...
When clouds are by the ground we call them fog. Nimbo (meaning “rain”) as a prefix, or nimbus added as a suffix, in a cloud name indicates that the cloud can produce precipitation (rain, snow, or other forms of falling water). Cumulo (meaning “heap”) refers to piled-up ...
Hail or graupel (small, soft hail) are usually found, if not at the ground, then aloft in virtually all cumulonimbus clouds that reach above the freezing level. If a pronounced flattening of the top of these clouds develops into a spreading anvil, then the cloud has achieved the status of...
Clouds form based on altitude, temperature, and moisture conditions in the atmosphere. Low-level clouds, like stratus and cumulus, form near the ground, while high-level clouds, like cirrus and alto, form higher up. A precipitation cloud forms when moisture droplets or ice crystals are big eno...
researchers have revealed that changes in cloud cover are helping to slightly counteract global warming. While greenhouse gases continue to drive temperatures upward, a reduction in low-cloud cover over land has contributed to a small decrease in the amount of heat retained near the Earth's ...
