They have Latin names as authorized by the World Meteorological Organization (WMO) that indicate physical structure, altitude or étage, and process of formation. They generally form from convection, with air parcels rising vertically into the atmosphere (called updrafts) and condensing into the puffy, cotton-like clouds that we all know and love. Test. We Got you Covered, How To Make Money For Sports Betting While Travelling. It is no secret that traveling is a source of sheer inspiration. Clouds may also form in contact with the ground surface, too. The main reason for the formation of these clouds is the velocity difference across the interface between two fluids. In section seven, extraterrestrial clouds can be found in the atmospheres of other planets in our solar system and beyond. The name cumulus comes from Latin and means "pile" or "heap." Stratus. Altostratogenitus – formed by the partial transformation of altostratus. Match. CloudMania: 12 Types of Clouds With Names And Their Weather Here are the Best States to Spot Some Winged Beauties! The formation consists of ice crystals and dust from meteor smoke. Altocumulus volutus (V27) elongated, tube shaped, horizontal stratocumuliform cloud. Thin scattered wave-cloud resembling cirrocumulus. The cloud formation looks beautiful when sunlight is reflected through them. The genus types all have Latin names. This section contains reference information for all AWS resource and property types that are supported by AWS CloudFormation. Cumulus tuba (WMO genus and supplementary feature) – column hanging from the bottom of cumulus. Stratus nebulosus translucidus undulatus (V-92), Stratus nebulosus opacus undulatus (V-93). None (always opaque except species fractus which is always translucent). These divisions are cross-classified to produce ten basic genus-types. Anvil rollover – (slang) circular protrusion attached to underside of anvil. Three of the five physical forms in the troposphere are also seen at these higher levels, stratiform, cirriform, and stratocumuliform, although the tops of very large cumulonimbiform clouds can penetrate the lower stratosphere. Cumulus praecipitatio (WMO genus and supplementary feature) – cumulus whose precipitation reaches the ground. The cloud formation is often confused with a UFO. To learn more about how clouds form, review the accompanying lesson, What is Cloud Formation? Murus: – "Wall": Cumulonimbus wall cloud with a lowering rotating base that can portend tornadoes. Noctilucent clouds are thin clouds that come in a variety of forms based from about 80 to 85 kilometres (262,000–279,000 ft) and occasionally seen in deep twilight after sunset and before sunrise. In fact, clouds are considered one of the most challenging aspects of climate science. Altostratus can bring light rain or snow. JRNZ TEACHER. These thick clouds are listed in approximate descending order of altitude of the cloud tops. Stratus fractus (WMO genus and species) – ragged detached portions of stratus cloud that usually form in precipitation (see also scud cloud). Created by. The following table shows the cloud varieties arranged across the top of the chart from left to right in approximate descending order of frequency of appearance. The different categories of clouds are then given names based on Latin words, eg nimbus clouds bring rain, stratus clouds … Cloud formation occurs when there is an unstable air condition. Additionally known as Hole Punch Clouds or Fallstreak Holes and are considered as a strange hole in the cloud layer. The What, Why, and How of Environmental Conservation. This lesson covers the following topics: Formation of clouds Mammatus Cloud. They are usually visible in twilight and it also depends on many factors. None (not generally discerned with highly unstable cumulus congestus). They are usually seen after the thunderstorm or the cold front. 4. The result is … In this method of classification there are four major types: layer clouds formed by the widespread regular ascent of air; layer clouds produced by widespread irregular stirring or turbulence; cumuliform clouds resulting from penetrative convection; and orographic clouds generated by the ascent of air … Clouds of the genus stratus form in low horizontal layers having a ragged or uniform base. There are three types of high clouds, all containing the word 'cirrus.' It should therefore be seen as an illustration of how the various cloud types are related to each other at all altitudes from surface-level to the "edge of space", rather than as a strict classification per se. Translucidus – "Translucent": Thin translucent patch or sheet of stratiform or stratocumuliform. Clouds resembling several terrestrial types can be seen over Mars and are believed to be composed of water-ice. Most genera and species can be subdivided into varieties, also with Latin names, some of which are common to more than one genus or species. Knuckles (informal variation of WMO supplementary feature mamma) – lumpy protrusion that hangs from edge or underside of anvil. 1. The reason for the formation of these clouds is the moist air when flows through the mountains resulting in the formation of waves on the downwind side and some of them take the form of the wave cloud. Clouds of the genus cirrostratus consist of mostly continuous, wide sheets of cloud that covers a large area of the sky. Cirrus homogenitus; cirrus formed by spreading of aircraft contrails. The site is also to cover things that are related to the world. Key Concepts: Terms in this set (32) Condense and water. Fibratus (Fib) – "Fibrous": Cirriform (Ci fib) or high stratiform (Cs fib) in the form of filaments, can be straight or slightly curved. Let me tell you there are many different kinds of cloud formations above in the sky. These cloud formations are of smoke and condensed water vapour. Altocumulogenitus – formed by the partial transformation of altocumulus mother cloud. The cloud formation often appears to be rolling slowly along its horizontal axis, however, Roll clouds are not and do not produce tornadoes. Collar cloud (WMO velum accessory cloud) – ring shape surrounding upper part of wall cloud. Genitus and mutatus types are the same as for cumulus of little vertical extent. Clouds of the genus cumulonimbus have very dark gray to nearly black flat bases and very high tops that can penetrate the tropopause. Comment document.getElementById("comment").setAttribute( "id", "ac38b09c2ada3585f4ae200236a0f757" );document.getElementById("a729cefbcf").setAttribute( "id", "comment" ); Save my name, email, and website in this browser for the next time I comment. After conducting the “Cloud in a Bottle” experiment on the next page, you should have a clearer understanding of both. Inflow band (informal term) – a laminar band marking inflow to a Cb, can occur at lower or mid levels of the cloud. 3. Wave-cloud resembling stratocumulus, especially as a polar cap cloud over the winter pole which is mostly composed of suspended frozen carbon dioxide.[21][22]. No varieties (always opaque and does not form in patterns visible from surface level). In sections three to five, terrestrial clouds are listed in descending order of the altitude range of each atmospheric layer in which clouds can form: In section six, the cloud types in the general lists and the mother clouds in the applicable classification table are sorted in alphabetical order except where noted. Your email address will not be published. Lacunosus – "Full of holes": Thin stratocumuliform cloud distinguished by holes and ragged edges. If a homogenitus cloud of one genus changes to another genus type, it is then termed a. Silvagenitus (silva-/pertaining to trees or forests) – formed by low-level condensation of water vapor released by vegetation, especially forest canopies. Cataractagenitus (cataracta-/pertaining to a river cataract) – formed from the mist at a waterfall, the downdraft caused from the cloud is counteracted by the ascending air displacement from the waterfall and may go on to form other types of clouds such as. During the ascent the rising air will get cooled adiabatically and when cooled below dew point, condensation takes place resulting in formation of convection clouds which are always of the cumulous type. Do post your comments. Perlucidus – "Semi-transparent": Sheet of stratocumuliform cloud with small spaces between elements. Vertebratus – "In the form of a back-bone": Cirriform arranged to look like the back-bone of a. Praecipitatio – Latin for "falling": Cloud whose precipitation reaches the ground. This is the value that AWS CloudFormation uses to provision the stack unless another value is provided. Stratus clouds hang low in the sky as a flat, featureless, uniform … Color: White or gray. The word 'cirrus' means 'wispy hair' in Latin, and these clouds definitely live up to their name. These currents put a force on the edges of the head to move downwards and again join the central column giving it an appearance of mushroom and hence the name. Small cumulus are commonly grouped with the low clouds because they do not show significant vertical extent. [4][5] At this altitude water almost always freezes so high clouds are generally composed of ice crystals or supercooled water droplets. Cloud types are sorted in alphabetical order except where noted. Cumulonimbus mamma (WMO genus and supplementary feature) – Cb with pouch-like protrusions that hang from under anvil or cloud base. There can be two conditions that result into formation of Mushroom clouds either by a manmade or natural explosion like a volcanic eruption, however, sometimes they have been seen in small explosions also like firing of a cannon. Talking about the appearance, the edge of the shelf clouds are smooth, However, at times they are layered or terraced. They are usually formed when the rush of moist air comes from the Gulf Stream and gets trapped between layers of dry air. The vertical height from base to top is generally less than the width of the cloud base. Surface - 2 km (surface - 7,000 ft) Clouds with Vertical Growth They are usually seen with UFO sightings. These are the 10 different types of clouds formations and their meanings. Learn. [19], Wave clouds with clear gaps through which lower stratiform layers may be seen.[20]. Stratus cataractagenitus are generated by the spray from waterfalls. [3], Tropospheric clouds are divided into physical forms defined by structure, and levels defined by altitude range. The genus types and some sub-types are arranged from top to bottom in approximate descending order of average overall altitude range. Not commonly seen with cumulus fractus or humilis. Here are... How big is your environmental footprint? Low cloud forms from near surface to ca. These clouds are also very rare to watch. Researchers all over the world have classified these cloud formations in different types, Let us discuss 10 different types of clouds formations and their meanings. According to studies, the clouds are ominous in appearance because they are harmless and does not have any relation with the tornados. In fact, clouds can help you predict upcoming weather. Lower-based convective clouds that can produce thunderstorms. We use cookies to ensure that we give you the best experience on our website. These cloud formations are also because of microburst activity. Cauda: – "Tail": A tail cloud that extends horizontally away from the murus cloud and is the result of air feeding into the storm. Anvil dome (WMO supplementary feature incus) – the. Keep a log of your studies and find a creative way to share your findings, which explain the water cycle and the process of cloud formation, to your supervisor. They are sorted from left to right in approximate decreasing order of frequency of occurrence for each of three categories. You can experience if you watch the sky daily and try to observe the change in patterns of the clouds. They are also called jellyfish clouds because of their appearance as you can see in below picture. Thick overcast clouds of sulfur dioxide and carbon dioxide in three main layers at altitudes of 45 to 65 km that obscure the planet's surface and can produce virga. A count of basic tropospheric variants that result from the division and subdivision of genus types into species and varieties is shown as a number in parentheses from V-1 (variant 1) through V-92 after each variety, after nimbostratus that has no sub-types, and after certain species that are not always dividable into varieties. Stratocumulus stratiformis (always dividable into opacity-based varieties), Stratocumulus stratiformis translucidus (V-67), Stratocumulus stratiformis perlucidus (V-68), Stratocumulus stratiformis translucidus radiatus (V-70), Stratocumulus stratiformis perlucidus radiatus (V-71), Stratocumulus stratiformis opacus radiatus (V-72), Stratocumulus stratiformis translucidus duplicatus (V-73), Stratocumulus stratiformis perlucidus duplicatus (V-74), Stratocumulus stratiformis opacus duplicatus (V-75), Stratocumulus lenticularis duplicatus (V-76), Stratocumulus stratiformis translucidus undulatus (V-77), Stratocumulus stratiformis perlucidus undulatus (V-78), Stratocumulus stratiformis opacus undulatus (V-79), Stratocumulus lenticularis undulatus (V-80), Stratocumulus stratiformis translucidus lacunosus (V-81), Stratocumulus stratiformis perlucidus lacunosus (V-82), Stratocumulus stratiformis opacus lacunosus (V-83).
