which of these cloud types is the most unstable?
437448
Cumulonimbus clouds indicate very unstable atmospheric conditions.

Weather is strongly affected by how stable or unstable the atmosphere is. Stable air means that the weather is likely to be calm. It may rain or snow slowly and steadily, it may be sunny, but the weather will not change quickly. Unstable air means that the weather might change quickly with very little warning.

A cumulonimbus incus (Latin incus, "anvil") also known as an anvil cloud is a cumulonimbus cloud which has reached the level of stratospheric stability and has formed the characteristic flat, anvil-top shape. It signifies the thunderstorm in its mature stage, succeeding the cumulonimbus calvus stage.

The types of clouds can be divided into three levels, each in turn with its own main groups of clouds. All in all, there are ten fundamental types of clouds. Often, you'll some places simply class clouds as cirrus, stratus, and cumulus because these clouds are the most common and representative for each altitude class.

There are five types of cloudy or nebulous objects in the sky: planetary nebulae, emission nebulae, reflection nebulae, dark nebulae and supernova remnants.

There are three main types of clouds. The stratus, the cumulus, and the cirrus.

If the layer of unstable air is deep, cumulonimbus clouds may form. If a cumuliform cloud receives a continuous supply of moist air, it will grow until it enters a layer of stable air. Air is said to be stable if the temperature of air rising inside a cloud decreases more quickly than the temperature outside the cloud.

A cumulonimbus cloud (CB) is dangerous because of the processes occurring in them. ... Threats within the cloud are severe turbulence, very strong updrafts (some as high as 100 m/s or more) and downdrafts containing torrential rain, hail and lightning.

Most of the time this is because there is insufficient heating/lifting or moisture to cause deeper (taller) cloud development. These clouds are too thin to produce rain, lightning, or waterspouts.

In a shallow conditionally unstable or absolutely unstable environment, one may expect clouds to develop, but their vertical growth will be limited, and may observe: cumulus humilis (shallow cumulus) stratocumulus In an absolutely stable environment, no clouds will likely form.

Types of severe weather phenomena vary, depending on the latitude, altitude, topography, and atmospheric conditions. High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, downbursts, tornadoes, waterspouts, tropical cyclones, and extratropical cyclones.

What are characteristics of unstable air? A) Turbulence and good surface visibility.

Because stable air masses are, by nature, calm and free of violent disturbances, they are often marked by the appearance of stratiform clouds or fog. Stratiform clouds can be identified by their smooth, sheetlike nature and do not build vertically like clouds found in unstable air masses with convective activity.

Cirrus clouds are thin and wispy clouds that are blown by high winds. ... Mid-level clouds are found in altitudes between 6,500 to 20,000 feet. They are formed mainly of water droplets, but can also be made up of ice crystals when the temperature is cold enough.

The list of cloud types groups the main genera as high (cirrus, cirro-), middle (alto-), multi-level (nimbostratus, cumulus, cumulonimbus), and low (stratus, strato-) according to the altitude level or levels at which each cloud is normally found.
