How about those pouch-like protrusions bulging from underneath larger clouds? The bottom of cumulus clouds are fairly close to the ground. While clouds are similar in many ways, there are lots of different types and they form in different ways. Other articles where stratocumulus is discussed: atmosphere: Cloud formation within the troposphere: are randomly distributed and as stratocumulus when they are organized into lines. They only occur when there are localized downdrafts striking through the stratocumuliform cloud. Cumulus clouds are the puffy clouds that look like puffs of cotton. Stratocumulus is a member of the ten fundamental cloud types (or cloud genera). To distinguish between a stratocumulus and an altocumulus cloud, point your hand toward the cloud. Theyre extremely common clouds that range from a light gray to dark gray in color with a sky cover of primarily cloudy to mostly sunny. From giant puffs billowing toward the sun to thin wisps slinking past the moon, clouds come in countless shapes and sizes. They are indicators of a change in the weather and are usually present near a warm, cold or occluded front. Vast areas of subtropical and polar oceans are covered with massive sheets of stratocumulus. It is a low-level cloud, thus it usually forms within the lowest two kilometers (6,600 ft) of the atmosphere. From thin wisps to threatening thunderheads, clouds tease our imaginations and play a critical role for life on Earth. A mans world? This website uses cookies. No precipitation in most cases. Low clouds fall into four divisions: cumulus, stratus, cumulonimbus, and stratocumulus. This equates to roughly 6,000 to 20,000 feet in altitude. Stratocumulus clouds have six supplementary features: asperitas, cavum, fluctus, mamma, praecipitatio, and virga. Sometimes they are so thin that the halo is the only indication that a cirrostratus cloud is in the sky. All rights reserved. Altostratus clouds cover the sky but are darker than cirrostratus clouds and may give the sun or moon a fuzzy appearance. Since cool air cannot hold as much moisture as warm air, the water condenses onto tiny dust particles that are floating in the air. Its also important to note that both clouds dont share any cloud species or varieties besides the radiatus cloud variety. Of course, all of the clouds that exist cant be contained within such limited parameters. Stratocumulus Perlucidus is a layer of stratocumulus clouds with small spaces, appearing in irregular pattern, through which clear sky or higher clouds can be seen. Remember, if youre trying to decide between an altostratus and stratocumulus cloud, and the cloud being observed has been determined to have an associated cloud species, its not an altostratus cloud. Stratus clouds are blanket clouds that sit low to the ground, and on occasion, come in contact with the ground, better known as fog. Omissions? Stratocumulus clouds have five associated cloud species: castellanus, floccus, lenticularis, stratiformis, and volutus. Stratocumulus usually occur as a distinct extensive layer or sheet of grey to white low clouds, in the form of more or less regular clumbs or patches often arranged in bands or rolls that lie across the wind.

And thats everything you should need to know about stratocumulus clouds, hopefully now identifying these cloud types should be much easier. Aside from sparking creativity, clouds serve several important scientific purposes, from helping meteorologists predict the weather to facilitating life on Earth. The terms hurricane, cyclone, and typhoon refer to the same weather phenomenon. This is a term used to denote a class of clouds that are flat and featureless capable of producing slight drizzles. Hence, stratocumulus cloud formations are seemingly bigger, and are generally a bit darker than altocumulus clouds. 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. Corrections? Stratocumulus clouds are often mistaken for rain clouds when in reality, it is quite rare to get anything more than the lightest drizzle from them, if anything at all. Any showers from stratocumulus castellanus are not usually as heavy as those from cumulus congestus. The clouds that cause thunderstorms are called stratocumulus clouds. These clouds are essentially above-ground fog formed either through the lifting of morning fog or through cold air moving at low altitudes over a region. Unauthorized use is prohibited. [1][2] Weak convective currents create shallow cloud layers because of drier, stable air above preventing continued vertical development. The study estimated that this would cause a surface warming of about 8C (14F) globally and 10C (18F) in the subtropics, which would be in addition to at least 4C (7.2F) already caused by such CO2 concentrarions. 283 lessons.

Cumulus congestus clouds extend into the middle troposphere, while deep, precipitating cumuliform clouds that extend throughout the troposphere are called cumulonimbus. The aurora borealis generally occurs five to 20 miles above the Earth's surface. Scientists just confirmed a 30-foot void first detected inside the monument years ago. You might already know what stratus clouds are: the flat, gray clouds that sit low in the sky. 'Dull weather' is a common expression incorporated with overcast stratocumulus days, which usually occur either in a warm sector between a warm and cold front in a depression, or in an area of high pressure, in the latter case, sometimes persisting over a specific area for several days. Stratocumulus clouds usually form from a layer of stratus cloud breaking up. They are formed when warm, moist air rises into the atmosphere.

In 2019, a study employed a large eddy simulation model to estimate that equatorial stratocumulus clouds could break up and scatter when CO2 levels rise above 1,200ppm (almost three times higher than the current levels, and over 4 times greater than the preindustrial levels). Some of the clouds you see in the sky could be from airplanes. A simple test to distinguish these is to compare the size of individual masses or rolls: when pointing one's hand in the direction of the cloud, if the cloud is about the size of the thumb, it is altocumulus; if it is the size of one's fist, it is stratocumulus. Middle clouds include Altostratus, altocumulus, and nimbostratus clouds. Stratocumulus is also often, though not always, darker in colour than altocumulus. On this Wikipedia the language links are at the top of the page across from the article title. They also can be formed by winds passing hills or mountains, such as Foehn winds, and in this case they can be very regularly shaped. [4], Stratocumulus Undulatus clouds appear as nearly parallel waves, rolls or separate elongated clouds, without significant vertical development.[4]. Stratocumulus Castellanus have stronger convective activity due to the presence of increasingly unstable air. Youll see both of these clouds at the same altitude but you should be able to differentiate these clouds easily as stratus clouds are featureless darker clouds, while stratocumulus clouds have a surplus of features. [10] Additionally, CO2 concentrations would only reach 1,200 ppm if the world follows Representative Concentration Pathway 8.5, which represents the highest possible greenhouse gas emission scenario and involves a massive expansion of coal infrastructure.
