In this article, we look at the strangest cloud formations and the science behind them.

This is the vastness of space that appears to be a dome covering the earth

Here are four amazing cloud formations in the heavens.

1. Nacreous clouds

Some of the most uncommon clouds on the globe are nacreous.


They are a type of polar stratospheric cloud, which is mostly to blame for the ozone layer's chemical deterioration.


When temperatures fall below -83C, minute amounts of moisture in the normally very dry stratosphere condense to generate wispy ice crystal clouds, which are visible close to the poles during the coldest of winters.


Nacreous clouds are always illuminated by the sun because they develop at elevations of up to 15,000 meters, where the ice crystals inside scatter and deflect light.


The chemical reactions that turn harmless carbons, known as chlorofluorocarbons, into chlorine, which is damaging to ozone, are accelerated by these colorful clouds.


2. Arcus

Roll or shelf clouds, also referred to as arcus clouds, are often found with intense storm clouds and thunderstorms.


Arcus clouds come in two varieties: shelf clouds and roll clouds, and they are typically visible behind cumulonimbus clouds or other ominous storm clouds.


For example, during or shortly before a storm, they require precise weather conditions and the right amount of moisture in the air to manifest.


3. Virga

Virga clouds are frequently compared to jellyfish because of their appearance, which is most evident when the sun is setting and a breeze is curling their long hanging tails.


When raindrop trails leave a cloud's underbelly but dissipate before touching the earth, virga clouds are created.


4. Mackerel Sky

Tall ships have low sails because of the Mackerel Sky and Mare's Tails. This saying dates back to a time when cloud formations were utilized to determine whether or not to lower the sails on boats and ships.


The expression, which is also known as "mackerel sky," is related to altocumulus clouds. The phrase "mare's tail" refers to cirrus clouds.


It is well known that the altocumulus and cirrus clouds that make up the mackerel sky formation frequently occur before a storm, which would cause sailors to lower their ships' sails.


Altocumulus clouds occur when the air has a certain amount of moisture, signaling the impending arrival of rain.
