The author took this photo. The shape of mammatus … Sometimes mammatus may form on other cloud types which produce no rain, though this is far less common. What is a gust front or outflow boundary? Riding a volcano Before one can start taking a closer, more in-depth look at the characteristics of mammatus clouds and the potential ways in which they develop, a more detailed definition of this phenomenon is required: Mammatus clouds are pouch-like protrusions (or sacs) that form below the base of a cloud formation, predominantly cumulonimbus clouds. High winds aloft can make the cloud's top into a flat anvil-like shape and their bottoms are usually very dark. But what exactly are these meteorological phenomena, what causes their very recognizable shape and features, and are they really as dangerous as they appear? Mammatus clouds are actually altocumulus, cirrus, cumulonimbus, or other types of clouds that have these pouch-like shapes hanging out of the bottom. They are the result of cold sinking air and predominantly consist of ice. Mammatus clouds often form at the base of t-storm anvils as the result of downward moving evaporationally cooled air entrains cloud particles bringing them downward.

And although their origins remain a mystery and a source of much debate, it has been established that these upside-down formations are the result of cold sinking air and typically form underneath the base of cumulonimbus clouds. Their unique appearance also makes it easy to distinguish them from other cloud types. 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. The interesting fact is that regardless of the shape and the looks of the cloud, they’re all made of the same thing – condensed water or ice. Cirrus Clouds. Mammatus clouds are some of the most unusual and distinctive clouds formations with a series of bulges or pouches emerging from the base of a cloud. The word "mammatus" is derived from the Latin word, "mamma," which translates to "breast" or "udder."

These pouches are created by cold air in the cloud sinking toward us. Everything you need to know about the forecast, and making the most of the weather. At this height, high winds will flatten the top of the cloud out into an anvil-like shape. Although predominantly associated with cumulonimbus clouds, mammatus formations can also be found at the base of other cloud types like altocumulus, altostratus, and cirrocumulus clouds. Mammatus clouds are visually striking pouch-like structures that typically form below the base of a cumulonimbus cloud formation. Their striking appearance is most visible when the sun is low in the sky and their pouches are framed by the sunlight. Due to its shape, this cloud is sometimes called the “mammary clouds.” According to meteorologists, these clouds arise from cumulonimbus rainclouds. Typically, turbulence within the cumulonimbus cloud will cause mammatus to form, especially on the underside of the projecting anvil as it rapidly descends to lower levels. On the contrary, mammatus clouds form as a result of sinking cold air that has enough momentum to continue descending until it passes through the cloud base of a cumulonimbus cloud and develop below it in the familiar "pouch-shaped" structures. A few common facts are known about mammatus cloud formation. Mammatus clouds, though, look ominous & threatening. 'Mammatus clouds are some of the most unusual and distinctive clouds formations with a series of bulges or pouches emerging from the base of a … Mammatus often forms in association with Cumulonimbus clouds, which in turn bring thunderstorms due to their huge mass of unstable air.
