What cloud is 18000 feet in the air?
Cirrus. Above 18,000 feet: Thin, wispy, and curled; often “horse-tail” shaped, these types of clouds are mostly comprised of ice crystals.
What are two types of clouds that are between 20000 and 6500 feet in the air?
Cirrostratus clouds are like very thin sheets of clouds that cover large parts of the sky. Cirrocumulus clouds look like small round puffs in the sky. Sometimes they are called mackerel clouds because they look similar to fish scales. Mid-level clouds are found in altitudes between 6,500 to 20,000 feet.
What clouds have bases between 6000 and 18000 feet?
Cumulonimbus clouds are the kings of all clouds, rising from low altitudes to more than 60,000 feet (20,000 meters) above ground level. They grow due to rising air currents called updrafts, with their tops flattening out into an anvil shape.
What clouds types occur above 18000 feet?
High clouds above 18,000 feet are cirrus clouds. Cirrus clouds are the most common of the high clouds. They are composed of ice and consist of long, thin, wispy streamers. Cirrus clouds are usually white and predict fair weather.

What are the 4 major types of clouds?
The Four Core Types of Clouds
- Cirro-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 cloud is below 6500 feet?
Low-level clouds: Low clouds occur below 6500 feet, and normally consist of liquid water droplets or even supercooled droplets, except during cold winter storms when ice crystals (and snow) comprise much of the clouds.
What altitude do cirrus clouds form?
2,000-18,000 ft. Typical Altitude: 2,000-18,000 ft. Cirrus clouds are the highest of all clouds and are composed entirely of ice crystals. Cirrus clouds are precipitating clouds, although the ice crystals evaporate high above the earth's surface.
What is the altitude of a cumulus cloud?
between 1,000 and 5,000ft Cumulus. These clouds usually form at altitudes between 1,000 and 5,000ft, though often temperature rises after formation lead to an increase in cloud base height. These clouds are generally formed by air rising as a result of surface heating and may occasionally produce light showers.
What is the altitude of a cirrus cloud?
2,000-18,000 ft. Typical Altitude: 2,000-18,000 ft. Cirrus clouds are the highest of all clouds and are composed entirely of ice crystals. Cirrus clouds are precipitating clouds, although the ice crystals evaporate high above the earth's surface.
What does nimbus cloud look like?
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. These are probably the least picturesque of all the main cloud types.
What are the 3 main cloud types?
While clouds appear in infinite shapes and sizes they fall into some basic forms. From his Essay of the Modifications of Clouds (1803) Luke Howard divided clouds into three categories; cirrus, cumulus and stratus. The Latin word 'cirro' means curl of hair.
What are the 4 classes of clouds based on altitude?
Within each altitude class additional classifications are defined based on four basic types and combinations thereof. These types are Cirrus (meaning hair like), Stratus (meaning layer), Cumulus (meaning pile) and Nimbus (meaning rain producing).
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.
What altitude are stratus clouds at?
Stratus clouds appear low in the atmosphere, below 6,500 feet (2 km). Stratus clouds at ground level are called fog. These clouds are made of small water droplets.
What does a altostratus cloud look like?
Altostratus clouds are mid-level, gray or blue-gray clouds that usually cover the whole sky. The Sun or moon may shine through an altostratus cloud, but will appear watery or fuzzy. If you see altostratus clouds, a storm with continuous rain or snow might be on its way.
What does a cirrostratus cloud look like?
Cirrostratus are transparent high clouds, which cover large areas of the sky. They sometimes produce white or coloured rings, spots or arcs of light around the Sun or Moon, that are known as halo phenomena. Sometimes they are so thin that the halo is the only indication that a cirrostratus cloud is in the sky.
At what altitude do cirrus clouds form?
Ice clouds, also called cirrus clouds, are made up of ice crystals and start to form at altitudes of 5.5 km in temperate regions and of 6.5 km in tropical regions, making them the highest clouds in the troposphere.
What is the altitude of cumulus clouds?
between 1,000 and 5,000ft Cumulus. These clouds usually form at altitudes between 1,000 and 5,000ft, though often temperature rises after formation lead to an increase in cloud base height. These clouds are generally formed by air rising as a result of surface heating and may occasionally produce light showers.
What are mackerel clouds?
(WMC) -A mackerel sky is a beautiful site and a common term for clouds made up of rows of altocumulus and cirrocumulus clouds. It appears as a rippling type pattern in the sky and it can look like fish scales in the sky.
What does a lenticular cloud look like?
They are often comparable in appearance to a lens or saucer. Nacreous clouds that form in the lower stratosphere sometimes have lenticular shapes….
| Lenticular cloud | |
|---|---|
| Genus | Stratocumulus, altocumulus, cirrocumulus |
| Species | lenticularis (Latin: lentil) |
| Altitude | up to 12,000 m (40,000 ft) |
| Appearance | lens-like, Saucer-shaped |
What is the difference between cirrus and cirrostratus?
Cirrus clouds are wispy, feathery, and composed entirely of ice crystals. They often are the first sign of an approaching warm front or upper-level jet streak. Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer (similar to what stratus clouds do in low levels).
What is the altitude of stratus clouds?
Stratus clouds appear low in the atmosphere, below 6,500 feet (2 km). Stratus clouds at ground level are called fog. These clouds are made of small water droplets.
What is a buttermilk sky?
noun. a cloudy sky resembling the mottled or clabbered appearance of buttermilk.
What do stratocumulus clouds mean?
Stratocumulus clouds are hybrids of layered stratus and cellular cumulus, i.e., individual cloud elements, characteristic of cumulo type clouds, clumped together in a continuous distribution, characteristic of strato type clouds. Stratocumulus also can be thought of as a layer of cloud clumps with thick and thin areas.

What does a mackerel sky?
A mackerel sky is a common term for clouds made up of rows of cirrocumulus or altocumulus clouds displaying an undulating, rippling pattern similar in appearance to fish scales; this is caused by high altitude atmospheric waves. Precipitation cloud? No, but may signify approaching precipitation.
What is difference between cumulus and stratocumulus?
Cumulus. Both stratocumulus and cumulus clouds are found at the same height, but stratocumulus clouds are more of a layer cloud than a cumulus cloud, usually found in conjoined groups or clumps of clouds. Additionally, stratocumulus clouds are generally darker than cumulus clouds.
