When we look at the sky there are many different scenes that show us the clouds depending on the weather conditions that are giving. The stratum clouds are horizontal layers extended in the sky with a uniform base, in opposition to the convective clouds or clusters. They have a uniform and extended layer. These clouds are usually formed at low altitude, covering much of the sky, and are a sign that there will be rainfall.
If you want to know more about What are the clouds strata and how they formcontinue with the reading of this interesting ecology article in which we explain it to you in detail.
What are the clouds strata
The strata clouds are a type of cloud that is characterized by its uniform and extended layer. These clouds usually form low altitude and cover much of the skygiving the appearance of a blanket or layer that extends horizontally. The stratum clouds are precipitation signalalthough if they are sufficiently low, they can become fog, mist or drizzle. They are mainly composed of drops of water and, sometimes, ice crystals.
Characteristics of clouds strata
The strata clouds have several distinctive characteristics that differentiate them from other types of clouds. Here are some of the most outstanding features:
- Altitude: They are formed at relatively low altitudes in the atmosphere, usually below 2,000 meters (6,500 feet), although they can extend to major altitudes. This low altitude contributes to its extended and horizontal appearance.
- Form and aspect: They have a flat and uniform appearance, covering large parts of the sky. Often, they are presented as a continuous cloud layer with diffuse edges. Sunlight can be filtered through them, but they usually spread the light, creating cloudy skies.
- Color: The clouds strata are usually gray or white, depending on the amount of sunlight that passes through them and the amount of water or ice they contain.
- Composition: They are mainly composed of water drops, but they can also have ice crystals, especially at colder altitudes.
- Variable thickness: The layer of clouds strata can vary in thickness, from thin clouds that allow sunlight to be denied to dense layers that completely hide the sun.
- Precipitation: Although strata clouds do not always produce precipitation, in some cases they are associated with drizzles, slight rains or snowfall. Precipitation is usually continuous but not very intense. In this link you can know different types of rainfall.
- Atmospheric stability: These clouds are usually forming in situations of atmospheric stability, where there is a soft and continuous rise of the air. Therefore, they are usually associated with calmer weather conditions.
- Common climates: The strata clouds are common in temperate climates, but can also be formed in other climates. Its presence may indicate more stable weather conditions, although not always.
These clouds are common in temperate climates and are frequently associated with more stable meteorological systems and calmer atmospheric conditions. However, its presence may vary, and strata clouds can also be formed in association with more dynamic weather systems.
How strata clouds are formed
The strata clouds are generally formed when there is a soft and continuous rise of the air, which allows moisture to condense and form an extended layer of clouds. Here is a general description of the training process of these clouds:
- Air Ascent: The strata clouds are formed when the air rises gently. This can occur in several ways, such as ground warming, air convergence, the rise associated with low pressure systems or orographic ascent due to the topography of the terrain.
- Air saturation: As the air rises, it cools. If the air contains enough moisture and cools enough, it will reach its dew point, which is the temperature in which the air is saturated and the humidity begins to condense in small drops of water or ice crystals.
- Water drop formation: In the case of strata clouds, condensation occurs in a relatively wide and uniform layer. Small drops of water are formed around dust particles or condensation nuclei in the air. These drops are so small and light that remain suspended in the atmosphere.
- Horizontal extension: The strata clouds extend horizontally, creating a uniform cloud layer in the lower part of the atmosphere.
- Uniform appearance: The layer of clouds strata tends to be dense and opaque, giving the appearance of a blanket that covers the sky. Often, there are no clearly defined limits among individual clouds, which contributes to its uniform appearance.
It is important to note that, although the strata clouds may be associated with cloudy conditions, they do not always produce significant precipitation. They can vary in thickness and density, and their presence may be related to both stable and unstable weather systems.
