Why Are Cirrocumulus Clouds Sometimes Called Mackerel Clouds?

When these clouds cover a lot of the sky, they can look like the scales of a fish, which is it is called a “mackerel sky

mackerel sky
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.

.” Cirrocumulus are common in winter and indicate fair, but cold, weather.

Clouds can make any scenery come alive. But have you ever wondered about the different kinds of clouds? In this article, we’ll look at how they’re categorized according to altitude. A cloud is a collection of ice crystals or water droplets. Not all clouds bring precipitation. Some indicate weather and help in forecasting.

These clouds have a patchy appearance. A Mackerel sky is one with cirrocumulus clouds. These clouds are called Mackerel because of their rippling pattern, which resembles fish scales (Mackerel is a common name for pelagic fish). Cirrocumulus clouds are mainly made of ice crystals. However, these clouds frequently also contain a small amount of supercooled water. Altitude: 5 to 15 kilometers.

There are also weather legends related to a mackerel sky, of course. Mackerel Sky, Mackerel Sky, Never Long Wet, Never Long Dry, for instance They were correctly recognized in the days of sailing ships as potential indicators of impending stormy weather: Mare’s tails and mackerel scales cause lofty ships to lower their sails. Is this supported by an actual weather fact? Why, of course it is. Cirrocumulus clouds are typically made up of ice crystals and form at altitudes of between 6,000 and 10,000 meters (18,000 and 30,000 feet). They frequently develop well before depressions and the fronts that go with them. Strong high-level winds are implied by the terms “mackerel skies” and “mare’s tails,” which refer to different cirrocumulus forms and twisted cirrus sheaves, respectively.

However, if a mackerel sky is composed of the slightly larger and darker altocumulus, they may suggest a temporary improvement. A typical altitude for the formation of altocumulus is between 3,000 and 6,000 meters (10,000 to 18,000 feet). However, if they are growing larger and thicker, they may later develop into a thunderstorm, which is frequently connected to a cold front.

They will thicken and the winds will change from being northwesterly to more southwesterly if they are ahead of an impending warm front. Often the winds will strengthen, too. A warm front’s typical width, from the first hazy clouds to the first signs of rain, is 500 km. You are approximately 400 km ahead of the rain if you see a mackerel sky. A system typically moves at a speed of around 50 kilometres per hour. So anticipate a change in the weather within the next six to eight hours.

The term “mackerel sky” (German: Schaefchenwolken; French: nuages moutonneux) is used to describe a sky with thick cirrocumulus or altocumulus clouds arranged in somewhat regular waves, with blue sky visible in the gaps between the clouds. The name comes from the pattern’s resemblance to a mackerel’s scales. Due to their pattern resembling a herd of sheep, they are known as sheep clouds in Germany and France. They are also occasionally referred to as buttermilk skies in specific regions.


What clouds are called mackerel clouds?

A mackerel sky, also known as a collection of rows of altocumulus and cirrocumulus clouds, is a stunning sight. It sometimes resembles fish scales in the sky and takes the form of a rippling pattern.

What is another name for a cirrocumulus clouds?

One of the three main genus-types of high-altitude tropospheric clouds, along with cirrus and cirrostratus, is cirrocumulus. Cirrocumulus clouds are classified as follows: GenusCirro- (curl) -cumulusSpeciesCastellanus Flocus Lenticularis StratiformisVarietyLacunosus UndulatusAltitude5,000-15,000 m (16,000-49,000 ft)
