2.02. 2.4. 1 Cumulus cloud systems. Cumulus clouds are formed by small thermals (upward-moving air parcels heated by contact to the warm ground) where condensation occurs and they grow to extend vertically throughout the troposphere. How is a cumulonimbus cloud created? Cumulonimbus clouds are born through convection, often growing fromRead More →
Optical depth and occurrence for both contrails and cirrus clouds are relatively similar. The thickness of contrails is similar to that of thin cirrus clouds, and both occur primarily in the winter months. What are the jets that make clouds? Contrails are human-made clouds. They form in air above aboutRead More →
Definition: Sheet of featureless, gray clouds in the middle cloud level capable of masking the sun. Description & Characteristics. Altostratus clouds are found in the middle cloud level. And unlike their altocumulus counterpart, they’re often boring to look at. What layer of the atmosphere are altostratus? stratiform clouds are knownRead More →
Meinrat Andreae of the Max Planck Institute for Chemistry in Mainz, Germany, and colleagues report that a surfeit of smoke particles can delay rainfall, because small droplets form instead of fewer, larger ones. These small droplets don’t fall as rain but rise higher up in the atmosphere, releasing energy asRead More →
Cumulonimbus clouds are a type of cumulus cloud associated with thunder storms and heavy precipitation. … These clouds often produce lightning in their heart. This is caused by ionized droplets in the clouds rubbing against each other. The static charge built up create lightning. What clouds produce precipitation? Almost allRead More →
Nimbostratus clouds are dark gray and thick enough to hide the sun completely. Unlike some other clouds, they don’t come in different shapes. You can’t look up at a nimbostratus cloud and guess what the shape of the cloud looks like – it just looks flat and gray, like aRead More →
Cumulonimbus clouds form in the lower part of the troposphere, the layer of the atmosphere closest to the surface of the Earth. This region due to evaporation and the greenhouse effect produces alot of the warm updrafts that make creation of cumulus and cumulonimbus clouds possible. What do cirrocumulus cloudsRead More →
Cirrostratus clouds are thin, white clouds that cover the whole sky like a veil. These clouds are most commonly seen in the winter, and can cause the appearance of a halo around the sun or the moon. Weather prediction: Rain or snow will arrive within 24 hours! What do cumulusRead More →
Cumulonimbus clouds are associated with extreme weather such as heavy torrential downpours, hail storms, lightning and even tornadoes. Individual cumulonimbus cells will usually dissipate within an hour once showers start falling, making for short-lived, heavy rain. Do cumulonimbus clouds bring rain? Cumulonimbus clouds are also called thunderheads. Thunderheads produce rain,Read More →
And they’re surrounded by tiny warm blankets of air, which lift them up towards the sky. That’s how clouds weighing billions of tonnes can stay afloat up in the sky. Are there clouds in the sky everyday? We see clouds nearly everyday. They float in the sky above us andRead More →
