As the proverb goes, “Mares’ tails and mackerel scales make lofty ships to carry low sails.” Together, wispy cirrus clouds resembling horse tails and patchy cirrocumulus signal that a rain storm is on its way. But scientists are interested in other messages these high altitude clouds can share.
What are horse tail clouds called?
cirrus uncinus
These are a type of cirrus cloud, known as cirrus uncinus. The name is derived from Latin and means “curly hooks”. The clouds occur at very high altitudes, at a temperature of about −50 to −40C. They are commonly known as mares’ tails because of their likeness to horse tails.

What is a cirrus cumulus cloud?

What do you call off clouds that indicate approaching bad weather?
Cumulonimbus clouds are associated with heavy rain, snow, hail, lightning and even tornadoes. The anvil usually points in the direction the storm is moving. Mammatus clouds are low hanging bulges that droop from cumulonimbus clouds. Mammatus clouds are usually associated with severe weather.
Do altostratus clouds rain?
However, altostratus clouds themselves do not produce significant precipitation at the surface, although sprinkles or occasionally light showers may occur from a thick alto- stratus deck. Altocumulus clouds exhibit “cumulo” type characteristics (see below) in mid levels, i.e., heap-like clouds with convective elements.
What are thick puffy clouds called?
Cumulus
Cumulus: Cumulus clouds are the clouds you learned to draw at an early age and that serve as the symbol of all clouds (much like the snowflake symbolizes winter). Their tops are rounded, puffy, and a brilliant white when sunlit, while their bottoms are flat and relatively dark.
What are cumulus clouds made of?
Cumulus clouds can be composed of ice crystals, water droplets, supercooled water droplets, or a mixture of them. The water droplets form when water vapor condenses on the nuclei, and they may then coalesce into larger and larger droplets.
What do cumulus clouds look like?
Cumulus clouds look like fluffy, white cotton balls in the sky. They are beautiful in sunsets, and their varying sizes and shapes can make them fun to observe! Stratus cloud often look like thin, white sheets covering the whole sky. Since they are so thin, they seldom produce much rain or snow.
What is the difference between cirrus clouds and cumulus clouds?
Cirrus clouds are fine and veil-like while the cumulus ones are dense, fluffy and look amassed. For instance, when we make out shapes of clouds, we usually do them with cumulus clouds.
What do cirrus and cumulus clouds have in common?
Cirrus clouds are the most common of the high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers….

How does cumulus clouds form?
Cumulus clouds are formed by small thermals (upward-moving air parcels heated by contact to the warm ground) where condensation occurs and they grow to extend vertically throughout the troposphere.
What is an uncinus cloud?
Translated from latin meaning hook, the ‘uncinus’ cloud species is found only in the cirrus cloud type. No other cloud type besides a cirrus cloud can be classified as uncinus. Cirrus uncinus cloud formations are a crowd-pleaser and is one of the more well-known cloud type and species combos because of their majestic and distinct look.

Can cirrus uncinus clouds predict bad weather?
Known as mares’ tails and sometimes referred to as comma clouds, cirrus uncinus clouds can predict bad weather in the upcoming 24-48 hours as they might signify an incoming weather front. Cirrus uncinus clouds are often seen in proximation with other cirrus cloud species.
What is a cumulus mediocris and cumulus congestus?
Cumulus mediocris – these are as wide as they are tall and are usually seen amongst a variety of other cumulus variations Cumulus congestus – these are taller than they are wide, looking like long chimneys capable of producing light showers
