What is the rarest cloud?

What causes clouds to be in a straight line?
Rising warm air cools gradually as it ascends into the atmosphere. When moisture in the warm air mass cools and condenses, it forms clouds. ... Cloud streets typically form fairly straight lines over large flat areas such as the ocean.May 18, 2018
What causes line clouds?
These clouds are contrails, short for condensation trails. Water vapor is one of the byproducts of jet fuel combustion and will turn into ice crystals in the cold air at the high elevations where jet airplanes fly. Those ice crystals create a cloud (the contrail), which does not pose any public health risk.Mar 8, 2018
What are nimbus clouds?
Nimbostratus clouds are dark, grey, featureless layers of cloud, thick enough to block out the Sun. Producing persistent rain, these clouds are often associated with frontal systems provided by mid-latitude cyclones.
What are ripple clouds?
What are cirrocumulus clouds? Cirrocumulus clouds are made up of lots of small white clouds called cloudlets, which are usually grouped together at high levels. Composed almost entirely from ice crystals, the little cloudlets are regularly spaced, often arranged as ripples in the sky.
What do cloud formations mean?
Though they look different, all clouds are condensed water droplets in the air. They form when warm, moist air rises upward. ... Except instead of spilling over the glass, the water in the air condenses around dust particles that are floating around. As these droplets build up in the sky, they form a cloud.Sep 27, 2021

What are black clouds called?
The clouds usually cover the entire sky. Weather prediction: Be prepared for continuous rain or snow! Nimbostratus clouds are dark, gray clouds that seem to fade into falling rain or snow. They are so thick that they often blot out the sunlight.

Do altostratus clouds rain?
Altostratus clouds are “strato” type clouds (see below) that possess a flat and uniform type texture in the mid levels. ... However, altostratus clouds themselves do not produce significant precipitation at the surface, although sprinkles or occasionally light showers may occur from a thick alto- stratus deck.

What does a stratus cloud look like in the sky?
- Stratus clouds hang low in the sky as a flat, featureless, uniform layer of grayish cloud. They resemble fog that hugs the horizon (instead of the ground). Stratus clouds are seen on dreary, overcast days and are associated with light mist or drizzle.

What type of Clouds do you see on cloudy days?
- You're likely to see stratocumulus on mostly cloudy days. They form when there's weak convection in the atmosphere. Altocumulus clouds are the most common clouds in the middle atmosphere. You'll recognize them as white or gray patches that dot the sky in large, rounded masses or clouds that are aligned in parallel bands.

What type of clouds are associated with rain and snow?
- Nimbostratus are the quintessential rain cloud. You'll see them whenever steady rain or snow is falling (or is forecast to fall) over a widespread area. Altostratus appear as gray or bluish-gray sheets of cloud that partially or totally cover the sky at mid-levels.

What is the average height of a high level cloud?
- Middle clouds (altocumulus, nimbostratus, altostratus) that form between 6,500 and 20,000 feet (1981–6,096 m) High-level clouds (cirrus, cirrocumulus, cirrostratus) that form above 20,000 feet (6,096 m) Cumulonimbus, which tower across the low, middle, and upper atmosphere
