What is a low level cloud called?
low level clouds (cumulus, stratus, stratocumulus) that lie below 6,500 feet; middle clouds (altocumulus, nimbostratus, altostratus) that form between 6,500 and 20,000 feet; high level clouds (cirrus, cirrocumulus, cirrostratus) that form above 20,000 feet;
What kind of clouds are white in the sky?
Cirrostratus 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 type of clouds are associated with fog?
Fog is a stratus cloud. Stratocumulus – Low clouds with irregular masses of clouds, rolling or puffy in appearance, sometimes with space between the clouds. Cumulonimbus – Large clouds with dark bases and tall billowing towers.
What type of clouds look like a roughened sea surface?
Asperitas are another cloud type that resembles a roughened sea surface. They appear as if you were underwater looking upward toward the surface when the sea is particularly roughened and chaotic. Although they look like dark and storm-like doomsday clouds, asperitas tend to develop after convective thunderstorm activity has developed.
What are low GREY clouds called?
StratusStratus: Stratus clouds hang low in the sky as a flat, featureless, uniform layer of grayish cloud. It resembles fog that hugs the horizon (instead of the ground).
What are GREY clouds called?
Stratus cloudsStratus clouds are uniform and flat, producing a gray layer of cloud cover which may be precipitation-free or may cause periods of light precipitation or drizzle.
What are low-level clouds called?
Low-Level Clouds. Cumulus (Cu), Stratocumulus (Sc), Stratus (St), and Cumulonimbus (Cb) are low clouds composed of water droplets. Cumulonimbus, with its strong vertical updraft, extends well into the the high level of clouds.
What cloud is low lumpy and gray?
StratocumulusCloud Index: Stratocumulus. Low, lumpy, grey sheets of cloud | by Duncan Geere | Looking Up | Medium.

What are the different clouds called?
This splits clouds into three main types - stratus, cumulus and cirrus....Names for cloudsStratus/strato: flat/layered and smooth.Cumulus/cumulo: heaped up/puffy, like cauliflower.Cirrus/cirro: high up/wispy.Alto: medium level.Nimbus/Nimbo: rain-bearing cloud.
What are nimbus clouds?
A nimbus cloud is a cloud that produces precipitation. Usually the precipitation reaches the ground as rain, hail, snow, or sleet. Falling precipitation may evaporate as virga. Since nimbus clouds are dense with water, they appear darker than other clouds.
Are stratus clouds high or low?
low-levelStratus clouds are low-level layers with a fairly uniform grey or white colour. Often the scene of dull, overcast days in its 'nebulosus' form, they can persist for long periods of time. They are the lowest-lying cloud type and sometimes appear at the surface in the form of mist or fog.
Are cumulus clouds high or low?
Their name derives from the Latin cumulo-, meaning heap or pile. Cumulus clouds are low-level clouds, generally less than 2,000 m (6,600 ft) in altitude unless they are the more vertical cumulus congestus form. Cumulus clouds may appear by themselves, in lines, or in clusters.
What are the names of the 4 types of clouds?
The Four Core Types of CloudsCirro-form. The Latin word 'cirro' means curl of hair. ... Cumulo-form. Generally detached clouds, they look like white fluffy cotton balls. ... Strato-form. From the Latin word for 'layer' these clouds are usually broad and fairly wide spread appearing like a blanket. ... Nimbo-form.
What do cirrus clouds look like?
Cirrus clouds are short, detached, hair-like clouds found at high altitudes. These delicate clouds are wispy, with a silky sheen, or look like tufts of hair. In the daytime, they are whiter than any other cloud in the sky. While the Sun is setting or rising, they may take on the colours of the sunset.
What do ripple clouds mean?
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 are the most common clouds in the middle 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. They look like the wool of sheep or scales of mackerel fish—hence their nicknames "sheep backs" and "mackerel skies.".
What are the white patches of clouds called?
Cirrocumulus clouds are small, white patches of clouds often arranged in rows that live at high altitudes and are made of ice crystals. Called "cloudlets, " the individual cloud mounds of cirrocumulus are much smaller than that of altocumulus and stratocumulus and often look like grains.
What are cumulonimbus clouds?
Cumulonimbus clouds are one of the few clouds that span the low, middle, and high layers. They resemble the cumulus clouds from which they grow, except they rise into towers with bulging upper portions that look like cauliflower. Cumulonimbus cloud tops are usually always flattened in the shape of an anvil or plume.
How to tell if it's Altocumulus or stratocumulus?
Besides altocumulus being higher up in the sky, another way to tell them apart is by the size of their individual cloud mounds. Place your hand up to the sky and in the direction of the cloud; if the mound is the size of your thumb, it's altocumulus. (If it's closer to fist-size, it's probably stratocumulus.)
What is a low, puffy, grayish or whitish cloud?
Stratocumulus. Danita Delimont/Getty Images. If you took an imaginary knife and spread cumulus clouds together across the sky but not into a smooth layer (like stratus), you'd get stratocumulus—these are low, puffy, grayish or whitish clouds that occur in patches with blue sky visible in between.
What clouds cover the sky in a dark gray layer?
Nimbostratus. Charlotte Benvie/Getty Images. Nimbostratus clouds cover the sky in a dark gray layer. They can extend from the low and middle layers of the atmosphere and are thick enough to blot out the sun.
What does Altostratus look like?
Altostratus appear as gray or bluish-gray sheets of cloud that partially or totally cover the sky at mid-levels. Even though they cover the sky, you can typically still see the sun as a dimly lit disk behind them, but not enough light shines through to cast shadows on the ground.
What are the different types of clouds?
2. Learn about types of clouds 1 Cirrocumulus – High clouds with a puffy, patchy appearance and small spaces between clouds. Often form wave-like patterns. 2 Cirrostratus – High clouds, light gray or white, often thin with the Sun or Moon seen through them. Usually cover much of the sky. 3 Cirrus – High clouds, thin wispy and feathery, composed of ice crystals.
What is the name of the cloud that covers the most of the sky?
Altocumulus – Middle clouds with a puffy, patchy appearance, usually with spaces between clouds. Altostratus – Middle clouds, light gray and uniform in appearance, generally covering most of the sky.
What is the difference between fog and stratus clouds?
Stratus – Low clouds, light or dark gray and generally uniform in appearance and covering most of the sky. Fog is a stratus cloud. Stratocumulus – Low clouds with irregular masses of clouds, rolling or puffy in appearance, sometimes with space between the clouds.
What are the two types of clouds that look like cotton balls?
Bases are diffuse and difficult to determine because of falling precipitation. Cumulus – Low clouds. Clouds appear puffy and look like cotton balls, popcorn or cauliflower.
What are the two types of clouds that cover much of the sky?
Often form wave-like patterns. Cirrostratus – High clouds, light gray or white, often thin with the Sun or Moon seen through them. Usually cover much of the sky. Cirrus – High clouds, thin wispy and feathery, composed of ice crystals.
How to use dichotomous key?
A dichotomous key is a tool scientists (and you!) can use to identify things in nature by answering yes or no questions. You can use this dichotomous key to identify types of clouds. 4. Make cloud (and weather) observations. Go outside or look out the window toward the sky to begin observations.
What are Altocumulus clouds made of?
Altocumulus clouds have several patchy white or gray layers, and seem to be made up of many small rows of fluffy ripples. They are lower than cirrus clouds, but still quite high. They are made of liquid water, but they don’t often produce rain. Weather prediction: Fair.
What is a Cirrus cloud?
Cirrus. Cirrus clouds are delicate, feathery clouds that are made mostly of ice crystals. Their wispy shape comes from wind currents which twist and spread the ice crystals into strands. Weather prediction: A change is on its way!
What is the name of the cloud that covers the whole sky like a veil?
Cirrostratus. 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!
Why are clouds still clouds?
They are still clouds, though, because they are made of water droplets condensed from the water vapor in the exhaust of the jet engines. Weather prediction: Contrails can provide information about the layers of moisture in the sky.
What is a dark cloud that fades into falling rain?
Nimbostratus. 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. Weather prediction: Gloomy with continuous rain or snow.
How do clouds form?
They can also be formed by sea breezes and often appear as lines where two air masses meet.
What are the indicators of severe weather?
Scientists have found that rapid growth and cooling at the tops of clouds are indicators of the potential for severe weather. The ABI can show more detailed changes in cloud-top features, helping scientists assess the potential size and severity of a storm even before it reaches its peak!
What is stratus cloud?
Stratus clouds are low lying clouds that form close to the ground.#N#They are usually flat and formless and a uniform grayish color. Many times they cover the entire sky.#N#Normally no precipitation is associated with these clouds, but sometimes a light mist or drizzle falls from them.#N#The name stratus means layer.#N#When stratus clouds touch the ground they are called fog.
What type of clouds form in a low, lumpy layer?
Stratocumulus clouds form in low, lumpy layers that appear in rows, patches, or round masses with blue sky visible between individual cloud masses.#N#They often appear at sunset.#N#Usually no precipitation is associated with these clouds.
What is the name of the storm cloud that is produced when a rotating column of air condenses?
One of the most feared and easily recognized storm clouds is the funnel cloud. Produced when a rotating column of air condenses, funnel clouds are the visible part of tornadoes that extend downward from the parent thunderstorm cloud. But remember, not until the funnel reaches the ground or "touches down" is it called a tornado. 07.
How do cumulonimbus clouds form?
But, whereas other clouds form when air currents rise several thousand feet and then condense where those currents stop, the convective air currents that create cumulonimbus are so powerful, their air rises tens of thousands of feet, condensing rapidly, and often while still journeying upward. The result is a cloud tower with bulging upper portions (that look something like cauliflower).
How do wall clouds form?
Wall clouds form as the thunderstorm updraft draws in air near the ground from several miles around, including from the nearby rain shaft. This rain-cooled air is very humid and the moisture within it quickly condenses below the rain-free base to create the wall cloud. 05. of 10.
What cloud type resembles a roughened sea surface?
Asperitas are another cloud type that resembles a roughened sea surface. They appear as if you were underwater looking upward toward the surface when the sea is particularly roughened and chaotic.
What is the name of the cloud that forms under the rain-free base of a storm?
Wall clouds form under the rain-free base (bottom) of cumulonimbus clouds. It takes its name from the fact that it resembles a dark gray wall (sometimes rotating) that lowers down from the base of the parent storm cloud, usually just before a tornado is about to form.
Why do clouds have anvils?
The anvil top of a cumulonimbus cloud is actually caused by it hitting the top of the stratosphere — the second layer of the atmosphere. Since this layer acts as a "cap" to convection (the cooler temperatures at its top discourage thunderstorms), the tops of storm clouds have nowhere to go but outward. Strong winds high up fan this cloud moisture ...
How do you tell if a storm is a roll or arcus?
Roll or arcus clouds are tube-shaped clouds that literally look like they've been rolled up into a horizontal band across the sky. They appear low in the sky and are one of the few severe weather clouds that are actually detached from the storm cloud base. (This is one trick for telling them apart from shelf clouds.) Spotting one is rare, but will tell you where a thunderstorm's gust front or another weather boundary, like cold fronts or sea breezes lay, since these clouds are formed by outflows of cold air.
