Cloud types

Looking at the sky and seeing clouds is the most common. Clouds are not only indicative of rain and storms, but they can give us information about the meteorology. There are different types of clouds in the sky and each one has different characteristics and formation conditions. In this article we will study the different types of clouds, what they mean and why they are formed.

How a cloud forms

Before we begin to describe the types of clouds we have to explain how they form. For there to be clouds in the sky, there must be a cooling of the air. The "loop" begins with the Sun. When the sun's rays heat the Earth's surface, they also heat the surrounding air. High-temperature air becomes less dense, so it tends to rise and be replaced by colder, denser air. As you go up in altitude, the environmental thermal gradient causes the temperatures to be lower. For this reason, the air is cooling.

When it reaches a cooler layer of air, it condenses into water vapor. This water vapor is invisible to the naked eye, since it is composed of water droplets and ice particles. The particles are so small in size that they are able to be held in the air by slight vertical currents.

The differences between the formations of different types of clouds are due to the condensation temperatures. There are some clouds that form at higher temperatures and some lower ones. The lower the formation temperature, the "thicker" the cloud will be. There are also some types of clouds that give rainfall and others that don't.

If the temperature is too low, the cloud that forms will be made up of ice crystals. It's also important to know how clouds dissipate, as this process influences the climate and weather forecast.

Another factor that affects cloud formation is air movement. Clouds that are created when the air is at rest tend to appear in layers or strata. On the other hand, those that are formed between winds or air with strong vertical currents present a great vertical development. Usually the latter are the cause of the rains and storms.

High clouds

We are going to differentiate the different types of clouds based on the altitude at which they form.

Cirrus

They are white clouds, transparent and without internal shadows. They appear as the well-known "horse tails". They are nothing but clouds formed by ice crystals due to the altitude at which they are. They are like long, thin filaments that have a more or less regular distribution in the form of parallel lines.

You can see it with the naked eye by looking at the sky and seeing how it looks like it's been painted with a brush. If the entire sky is covered in cirrus clouds, it's very likely that we'll experience a sudden change in the weather in the next 24 hours. These usually involve changes in temperature decline. For more information about these phenomena, you can consult cirrus clouds.

Cirrocumulus

These clouds form an almost continuous layer that have a wrinkled surface appearance and with rounded shapes as if they were small cotton flakes. The clouds are totally white without presenting any shadow. When the sky appears covered with this type of clouds, it is said to be bored. It is similar to the weaving of sheep.

They often appear alongside cirrus clouds and indicate that the weather changes by about twelve hours. When they appear, they usually precede a storm. Obviously, they don't always indicate the same thing. If they did, meteorology and weather forecasting would be much simpler. To learn more about altocumulus clouds, you can read altocumulus clouds.

Cirrostratus

They seem at first glance like a veil from which it is difficult to distinguish the details. Sometimes the edges can be noticed as they are long and wide striated. They are easily identified because they form a halo in the sky around both the sun and the moon. They tend to happen to cirrus clouds and indicate that bad weather or some warm forehead.

Medium clouds

Among the different types of medium clouds we find:

Altocumulus

They are flake-shaped clouds of medium size and irregular structure. These clouds do present flakes and ripples in their lower part. Altocumulus indicate that bad weather is beginning Whether due to rain or storms. To learn more about this type of cloud, you can visit our website.

High Stratus

These are clouds with thin layers and some denser areas. In most cases the sun can be seen through the cloud cover. The appearance is similar to irregular spots. They portend fine rain due to a drop in temperature. You can learn more about these clouds in our article on .

Low clouds

They are the closest to the surface. Among them we have:

Nimbostratus

They appear as a regular dark gray layer with varying degrees of opacity. It is because the density varies throughout the cloud. They are typical of the spring and summer rains. They can also be found in rainfall in the form of snow.

Stratocumulus

These clouds have undulations similar to elongated cylinders. They also have some undulations in different shades of gray. They rarely bring rain. For more information on stratus clouds, you can visit our article on the strata.

Strata

The appearance is that of a grayish haze without being able to see the well defined structures. It has some buttresses of different degrees of opacity. During the colder months they are able to endure throughout the day, giving the landscape a more gloomy appearance. When spring arrives they appear during the early morning and disperse during the day. Indicates good weather. It is essential to know these types of clouds in order to correctly interpret the weather.

Clouds vertical development

These are the clouds that present massive degrees of size and rainfall.

Cumulus clouds

They have a denser appearance and very marked shadows, to the point of blocking the sun. They are gray clouds. Its base is horizontal, but its upper part has large protrusions. Cumulus clouds correspond to good weather when there is little ambient humidity and little vertical air movement. They are capable of causing downpours and storms. For more information on the topic, we invite you to discover our article on the cumulus.

Cumulonimbus

They are the largest and most massive-looking clouds with great vertical development. They are gray in color and completely cover the sun. These are the typical ones that occur in storms and even produce hail.
