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.
Which clouds are mares tails?
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.
Why are cirrus clouds called mares tails?

What do mares tails clouds look like?
Mare’s tails are cirrus clouds found high in the atmosphere, which are pulled into long streamers resembling the tail of a horse. Mackerel scales are altocumulus clouds which look like fish scales.
How do I get rid of mare’s tail?
One application of weedkiller is unlikely to kill all the horsetail. You will need to spray once, allow the horsetail to die down, and then spray the regrowth again. Three or more applications a year, over a couple of years, may be needed to completely kill it, depending on how extensive the root system is.
Does a mackerel sky mean rain?
A mackerel sky is a common term for clouds made up of rows of cirrocumulus or altocumulus clouds displaying an undulating, rippling pattern similar in appearance to fish scales; this is caused by high altitude atmospheric waves. Precipitation cloud? No, but may signify approaching precipitation.
What are the clouds that look like cotton balls?
Cumulus clouds are puffy shaped. They may look like popcorn or cotton and have flat bottoms. They are low in the sky.
What do you call a rain cloud?
(“Nimbus” comes from the Latin word for “rain.”) Two examples are the nimbostratus or cumulonimbus clouds. Nimbostratus clouds bring continuous precipitation that can last for many hours. These low-level clouds are full of moisture. Cumulonimbus clouds are also called thunderheads.
What does Mackerel Sky mean weather?
A mackerel sky can be used to forecast weather, but it is at the more challenging end of the weather lore spectrum. The simple bit is this: a mackerel sky of any kind means change is likely. This is reflected in the associated weather lore: ‘Mackerel sky, mackerel sky – never long wet, never long dry.
What is the highest clouds in the sky?
Cirrus clouds are the highest of all clouds and are composed entirely of ice crystals. Cirrus clouds are precipitating clouds, although the ice crystals evaporate high above the earth’s surface.
What are 3 facts about cirrus clouds?
To decide if a cloud is a cirrus cloud, look for these things:
- The clouds are a very vivid white color.
- The clouds are floating very high up in the sky.
- The clouds are thin, feathery, and wispy.
- The cloud wisps are individual and not connected to each other.
What are wispy clouds called?
Cirrus clouds are wispy, feathery, and composed entirely of ice crystals. They often are the first sign of an approaching warm front or upper-level jet streak. Unlike cirrus, cirrostratus clouds form more of a widespread, veil-like layer (similar to what stratus clouds do in low levels).
What clouds forming in a mackerel sky?
(WMC) -A mackerel sky is a beautiful site and a common term for clouds made up of rows of altocumulus and cirrocumulus clouds. It appears as a rippling type pattern in the sky and it can look like fish scales in the sky.
What are the different cloud types?
There are ten main types of clouds:
Which clouds look like cotton balls and mean fair weather?
On a sunny day, the sun’s radiation heats the land, which in turn heats the air just above it. This warmed air rises by convection and forms Cumulus. These “fair weather” clouds look like cotton wool.
Can horsetail grow through concrete?
The plant’s growing season begins properly in March and lasts until the winter. The plant reproduces by releasing spores, and as a result it can spread great distances. Horsetail is able to grow through tarmac and cement surfaces and commonly causes damage to driveways and paved areas.
How do you stop horsetail from spreading?
Remove rhizomes by digging as deeply as possible. The deep roots of established horsetail colonies will re-grow. Regularly removing the shoots and rhizomes as soon as they appear will weaken the plants, but total eradication requires determination over a number of years.
How deep are mares tail roots?
The plant has creeping rhizomes which can go down as deep as 7m which makes them extremely difficult to remove, especially if they are invading a border. They are known for entering gardens by spreading underground from neighbouring land or properties.
What does pink sky at night mean?
You may have also heard a similar saying, which goes: ‘Pink sky at night, sailor’s delight’. It has exactly the same meaning, but refers to workers at sea, rather than on farms. The Met Office has confirmed that these old adages are generally true, as it’s all to do with pressure systems that control the weather.
What does a red sky at night mean?
A red sky appears when dust and small particles are trapped in the atmosphere by high pressure. This scatters blue light leaving only red light to give the sky its notable appearance. A red sky at sunset means high pressure is moving in from the west, so therefore the next day will usually be dry and pleasant.
