4 types of clouds

These ordinal instability numbers appear in each box where a particular genus has a particular species. Clouds resembling several terrestrial types can be seen over Mars and are believed to be composed of water-ice. They are characterized by their woolly, round/oval shaped appearance. Nebulosus (Neb) – "Nebulous": Indistinct low and high stratiform (St neb, Cs neb) without features; indicates light wind if any and stable air mass. Not commonly seen with cumulus fractus or humilis. Due to the refraction of light by ice crystals, these clouds form the rainbow-colored halos we often see forming around the sun. The 4 Types Of Clouds And The 10 Specific Cloud Systems Associated With Each One. But do you know how much you can really tell from knowing what type of cloud you are looking at? If they do grow tall, they can turn into thunderstorms. As an observer standing on the ground and looking up into the sky, you'll see three basic types of clouds: cirrus, stratus and cumulus. Lower-based convective clouds that can produce thunderstorms. Stratus cataractagenitus are generated by the spray from waterfalls. Burroughs, William James; Crowder, Bob (January 2007). To be honest, it can even be confusing for some seasoned weather enthusiasts. The form of classification that makes the most sense and is widely accepted in the meteorological community, is the one we will focus on in this article. Download PDF. Surface - 2 km (surface - 7,000 ft) Clouds with Vertical Growth. [1][2], Polar stratospheric clouds form at very high altitudes in polar regions of the stratosphere. Different types of clouds form along warm fronts and cold fronts, and a field forecaster should be able to tell what weather is coming by reading the cloud shapes and height. Cumulus clouds appear during sunny days early in the day and disappear towards the evening. Know more about the cloud names and their classification. The supplementary features are associated with particular genera as follows. Cumulus tuba (WMO genus and supplementary feature) – column hanging from the bottom of cumulus. Clouds: a cloud is a visible accumulation of small droplets of water, ice crystals or a mix of both suspended in the air. Middle clouds seldom produce any rainfall. [4][5] At this altitude water almost always freezes so high clouds are generally composed of ice crystals or supercooled water droplets. Defining Humidity And Its Characteristics, Solar Halos: Defining The Rings Around The Sun. The exceptions comprise the following: Altostratus that have varieties but no species so the applicable boxes are marked without specific species names; cumulus congestus, a species that has its own altitude characteristic but no varieties; cumulonimbus that have species but no varieties, and nimbostratus that has no species or varieties. Play this game to review Earth Sciences. The aim of this article is to make it as easy as possible for you to learn to distinguish the different types of clouds from each. Cavum – "Hole": Supercooled altocumulus or cirrocumulus distinguished by a hole with ragged edges and virga or wisps of cirrus. The possible combinations of genera and mother clouds can be seen in this table. Weather prediction: Severe weather might be on its way! They are called multi-level clouds because of their ability to spread through the lower, middle, and upper cloud levels. The lower levels of a cumulonimbus cloud consists mainly of water droplets, while the upper level, where temperatures are well below zero, mainly consists of ice crystals and supercooled water.

Translucidus – "Translucent": Thin translucent patch or sheet of stratiform or stratocumuliform. 193 plays . As with Cirrus clouds, they appear and are associated with clear and pleasant weather conditions. There are much, much more but these are the four basic types of clouds. In fact, fog is nothing more than a form of stratus cloud that forms at ground level. 4. They are clouds that are shared between a number of organisations. Clouds with upward-growing vertical development usually form below 2 kilometres (6,600 ft),[5] but can be based as high as 2.5 kilometres (8,200 ft) in temperate climates, and often much higher in arid regions. The genera are also grouped into five physical forms. Clouds of the genus stratus form in low horizontal layers having a ragged or uniform base. Within the troposphere, the cloud levels are listed in descending order of altitude range. Bands of cloud resembling cirrus located mainly in the highest of three main layers that cover Jupiter.[24]. Velum – "A ship's sail": An accessory cloud in the form of a sail. At these heights temperatures are below freezing point, meaning the water moisture in the clouds is in the form of ice crystals or supercooled water droplets. These divisions are cross-classified to produce ten basic genus-types. Tropospheric clouds are divided into physical forms defined by structure, and levels defined by altitude range. Small cumulus are commonly grouped with the low clouds because they do not show significant vertical extent. The veil of milky looking clouds can sometimes cover almost the entire sky. Cumulus praecipitatio (WMO genus and supplementary feature) – cumulus whose precipitation reaches the ground. Precipitation-based supplementary features. 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. Homogenitus (homo-/pertaining to humans) – formed as a result of human activities, particularly aircraft at high altitudes and heat-generating industrial activities at surface level. 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]. Murus: – "Wall": Cumulonimbus wall cloud with a lowering rotating base that can portend tornadoes. While there are 6 as a part of this lesson, the “extra” two are part of one of the main four listed in the sentence before. 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. Condensation funnel (WMO supplementary feature tuba) – the cloud of a. Cumulus pileus (WMO genus and accessory cloud) – capped, hood-shaped cumulus cloud.
