Clouds are formed in the Earth's atmosphere when water evaporates into vapor from
oceans, lakes, ponds, and even streams and rivers; and by evaporation or transpiration
over moist areas of Earth's land surface. The vapor rises up into co lder areas of
theatmosphere due to convective, orographic, or frontal lifting.

Mammatus, also known as mammatocumulus (meaning "mammary cloud" or "breast
cloud"), is a meteorological term applied to a cellular pattern of pouches hanging
underneath the base of a cloud. The name mammatus, derived from the Latin mamma
(meaning "udder" or "breast"), refers to a resemblance between the characteristic shape of

these clouds and the breast of a woman.
2.Lenticular cloud, Mt. Fuji, Japan
Lenticular clouds (Altocumulus lenticularis) are stationary lens-shaped clouds that form at
high altitudes, normally aligned perpendicular to the wind direction. Lenticular clouds can be
separated into altocumulus standing lenticularis (ACSL), stratocumulus standing lenticular
(SCSL), and cirrocumulus standing lenticular (CCSL). Due to their shape, they have been
offered as an explanation for some Unidentified Flying Object (UFO) sightings.

Undulatus asperatus (or alternately, asperatus) is a cloud formation, proposed in 2009 as a
separate cloud classification by the founder of the Cloud Appreciation Society. If successful
it will be the first cloud formation added since cirrus intortus in 1951 to the International
Cloud Atlas of the World Meteorological Organization. The name translates approximately
as roughened or agitated waves.

An arcus cloud is a low, horizontal cloud formation. Roll clouds and shelf clouds are the two
types of arcus clouds. A shelf cloud is usually associated with the leading edge of
thunderstorm outflow; roll clouds are usually formed by outflows of co ld air from sea
breezes or cold fronts in the absence of thunderstorms

Polar stratospheric clouds or PSCs, also known as nacreous clouds, are clouds in the winter
polar stratosphere at altitudes of 15,000–25,000 meters (49,000–82,000 ft). They are
implicated in the formation of ozone holes; their effects on ozone depletion arise because
they support chemical reactions that produce active chlorine which catalyzes ozone
destruction, and also because they remove gaseous nitric acid, perturbing nitrogen and
chlorine cycles in a way which increases ozone destruction.

Cumulonimbus (Cb) is a towering vertical cloud (family D2) that is very tall, dense, and
involved in thunderstorms and other inclement weather. Cumulonimbus originates from
Latin: Cumulus “heap” and nimbus “cloud”. It is a result of atmospheric instability. These
clouds can form alone, in clusters, or along a cold front in a squall line. They can create
lightning and other dangerous severe weather. Cumulonimbus clouds form from cumulus
clouds (namely from cumulus congestus) and can further develop into a supercell, a severe
thunderstorm with special features.

Altocumulus is a cloud belonging to a class characterized by globular masses or rolls in
layers or patches, the individual elements being larger and darker than those of
cirrocumulus and smaller than those of stratocumulus. Like other cumulus clouds,
altocumulus signifies convection. It is usually white or grey, and often occurs in sheets or
patches with wavy, rounded masses or rolls. A sheet of partially conjoined altocumulus
perlucidus is sometimes found preceding a weakening warm front, where the altostratus is
starting to fragment, resulting in patches of altocumulus perlucidus between the areas of
altostratus, or more rarely, an entire sky of the perlucidus variety.

Night clouds or noctilucent clouds are tenuous cloud-like phenomena that are the “ragged-
edge” of a much brighter and pervasive polar cloud layer called polar mesospheric clouds in
the upper atmosphere, visible in a deep twilight. They are made of crystals of water ice.
Noctilucent roughly means night shining in Latin. They are most commonly observed in the
summer months at latitudes between 50° and 70° north and south of the equator. They
can only be observed when the Sun is below the horizon. They are the highest clouds in the
Earth’s atmosphere, located in the mesosphere at altitudes of around 76 to 85 kilometres
(47 to 53 mi). They are normally too faint to be seen, and are visible only when illuminated
by sunlight from below the horizon while the lower layers of the atmosphere are in the
Earth’s shadow. Noctilucent clouds are not fully understood and are a recently-discovered
meteorological phenomenon; there is no record of their observation before 1885.
Noctilucent clouds can form only under very restrictive conditions; their occurrence can be
used as a sensitive guide to changes in the upper atmosphere. They are a relatively recent
classification. The occurrence of noctilucent clouds appears to be increasing in frequency,
brightness and extent. It is theorized that this increase is connected to climate change.

The Morning Glory cloud is a rare meteoro logical phenomenon occasionally observed in
different locations around the world. The southern part of Northern Australia’s Gulf of
Carpentaria is the only known location where it can be predicted and observed on a more
or less regular basis. The settlement of Burketown attracts glider pilots intent on riding this
phenomenon.

A fog bow is a similar phenomenon to a rainbow, however, as its name suggests, it
appears as a bow in fog rather than rain. Because of the very small size of water droplets
that cause fog—smaller than 0.05 millimeters (0.0020 in)—the fog bow has only very weak
colors, with a red outer edge and bluish inner edge.
In many cases when the droplets are very small, fog bows appear white, and are therefore
sometimes called white rainbows. This lack of color is a feature of a fog bow which
distinguishes it from a glory, which has multiple pale co lored rings caused by diffraction.
When the droplets forming it are almost all of the same size the fog bow can have multiple
inner rings, or supernumeraries, that are more strongly colored than the main bow.

types of arcus clouds. A shelf cloud is usually associated with the leading edge of

A waterspout is an intense co lumnar vortex (usually appearing as a funnel-shaped cloud)
that occurs over a body of water, connected to a cumuliform cloud. In the common form,
it is a non-supercell tornado over water. While it is often weaker than most of its land
counterparts, stronger versions spawned by mesocyclones do occur. Waterspouts do not
suck up water; the water seen in the main funnel cloud is actually water droplets formed by
condensation. While many waterspouts form in the tropics, locations at higher latitude
within temperate zones also report waterspouts, such as Europe and the Great Lakes.
Although rare, waterspouts have been observed in connection with lake-effect snow
precipitation bands.
