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 types of clouds are the low clouds up to 6500 feet?

Altostratus form a gray or bluish-gray uniform- looking layer that covers much or most of the sky. Low-level clouds are found below about 6,500 feet (2,000 meters).

What kind of clouds are at 5000 feet?

Cumulonimbus. Cloud base is typically between 2,000 and 5,000ft, though in some cases this may be lower or higher. These clouds are formed when conditions are such that deep convection is able to develop, and may have a huge vertical extent particularly in the tropics, sometimes reaching the tropopause.

What type of clouds are found below 6000 feet?

Low clouds (stratus, stratocumulus, nimbostratus) can form anywhere from the ground to an altitude of approximately 6,000 feet. Fog is simply a low cloud in contact with the earth’s surface.

What type of cloud is between 6500 feet to 18000 feet in the atmosphere?

Altocumulus clouds hang high in the sky and are above the influence of thermals, causing them to form differently. Instead of having a puffy appearance, they appear more scattered. These clouds hang at an altitude of 6,500-18,000 feet in the sky.

What are the low clouds called?

Low-level clouds (0-2 km): stratus, cumulus, cumulonimbus, and stratocumulus.

What are the lower level clouds?

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.

Where are cumulonimbus clouds found?

Cumulonimbus clouds form in the lower part of the troposphere, the layer of the atmosphere closest to the surface of the Earth.

Which clouds are found lowest below 6000 feet in the atmosphere?

Stratus: The lowest clouds, they hang like a ceiling at less than 6,000 feet. Their name comes from the Latin word to spread, as in layers. These clouds appear as a general overcast and can produce widespread rain and snow. Altostratus: Wispy clouds that are found at middle elevations.

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 clouds are at 40000 feet?

CIRROCUMULUS clouds form between 20,000 and 40,000 feet.

What kind of clouds are snow clouds?

Altostratus Clouds – Altostratus clouds, also known as snow clouds, are gray or blue-gray clouds that completely cover the sky. They’re made of dense ice crystals and water droplets that can precipitate either continuous rain or snow.

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 are 2 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.

How high up are cumulonimbus clouds?

Fueled by vigorous convective updrafts (sometimes in excess 50 knots), the tops of cumulonimbus clouds can easily reach 39,000 feet (12,000 meters) or higher.

What are two common types of Nimbo form clouds?

Nimbostratus cloudGenusNimbostratus (rain, layered)SpeciesnoneVarietynoneAltitude500-5,500 m (2,000-18,000 ft)

What is the 4 types of clouds?

What are all 10 cloud types?

The foundation consists of 10 major cloud types. In addition to cirrus, stratus, cumulus, and nimbus clouds, there are cirrostratus, cirrocumulus, altostratus, altocumulus, stratocumulus, nimbostratus, and cumulonimbus clouds. The following table places these cloud types into the four major cloud groups.

What does low cloud mean?

The lighter warm air is forced to rise over the cold air mass, leading to cloud formation. The lowering clouds indicate that the front is drawing near, giving a period of rain in the next 12 hours.

What are the three types of cloud?

Cumulus, Stratus, and Cirrus. There are three main cloud types.

What are the 5 names of the low-level clouds?

Clouds with a base below 6,500 ft including cumulus, cumulonimbus, stratocumulus and stratus.

Are stratus clouds high or low?

Stratus 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.

Which type of cloud is a middle altitude cloud?

18,000 – 8,000 ft. Clouds of the middle level are usually of the altocumulus or altostratus type with bases normally in the range from 6,500 feet to 23,000 feet (2,000 to 6,000 meters).

What do flat bottom clouds mean?

You are referring to cumulus clouds, the most common daytime clouds in the summer sky. … The flat bottom of cumulus clouds defines the exact height at which a critical combination of temperature and air pressure causes water vapor within the rising current to condense into a visible cloud.

Are vertical clouds considered low level clouds?

Low – Low level clouds form below 6,500 feet. They are often composed of mostly water droplets. Low level clouds usually have the word “stratus” in their name. Vertical – Some clouds are vertical clouds.

What type of cloud is cumulonimbus?

Cumulonimbus clouds are menacing looking multi-level clouds, extending high into the sky in towers or plumes. More commonly known as thunderclouds, cumulonimbus is the only cloud type that can produce hail, thunder and lightning.

Which cloud formation is classified as cumulonimbus?

The cumulonimbus cloud, or thunderstorm, is a convective cloud or cloud system that produces rainfall and lightning. It often produces large hail, severe wind gusts, tornadoes, and heavy rainfall.

Which type of charge is found at the lower end of the cumulonimbus clouds?

The result is that the upper part of the thunderstorm cloud becomes positively charged while the middle to lower part of the thunderstorm cloud becomes negatively charged (Figure 3).

How high is a cirrostratus cloud?

Cirrostratus cloudVarietyDuplicatus UndulatusAltitude6,000 – 13,000 m (20,000 – 43,000 ft)ClassificationFamily A (High-level)AppearanceThin, transparent, high-altitude layer capable of producing a halo.

Are stratocumulus clouds?

Stratocumulus clouds are low-level clumps or patches of cloud varying in colour from bright white to dark grey. They are the most common clouds on earth recognised by their well-defined bases, with some parts often darker than others. They usually have gaps between them, but they can also be joined together.

What is a rain cloud called?

Clouds that produce rain and snow fall into this category. (“Nimbus” comes from the Latin word for “rain.”) Two examples are the nimbostratus or cumulonimbus clouds. … These low-level clouds are full of moisture. Cumulonimbus clouds are also called thunderheads. Thunderheads produce rain, thunder, and lightning.
