Cencellada: What is it, how it is formed and types

The cencellada is a meteorological phenomenon that occurs in specific conditions of temperature and humidity. This is the Formation of an ice layer on exposed surfacessuch as tree branches, leaves, grass and other objects, due to the freezing of water vapor present in the air.

This phenomenon occurs in environments with High relative humidity and temperatures near the freezing point. When the ambient temperature is low enough, the water vapor in the air is directly condensed in the form of ice on the aforementioned surfaces, creating a thin layer of calell. Although visually resembles the frost, the cencelllada is distinguished by its formation from the direct ice deposition, without going through the liquid phase.

The cencellada process is more common in Rural environments and in natural landscapeswhere the exposed surfaces allow the ice to accumulate more easily. In addition, the cencellada can lead to picturesque landscapes, transforming the appearance of natural elements by covering them with delicate layers of ice. Although the cencellada can offer impressive visual scenes, it can also represent a Challenge for mobility and securitysince affected surfaces can become slippery.

The formation of the cencellada implies a specific combination of weather factors. First, a Atmosphere with a significant amount of water vapor. This steam can come from various sources, such as the evaporation of nearby water bodies, plant perspiration or even soil humidity.

The next key condition is ambient temperature. The cencellada generally occurs in conditions close to the water freezing pointwhich is 0 degrees Celsius. In these circumstances, the water vapor in the air cools enough to move from the gas phase to the solid phase, directly forming small ice crystals on the exposed surfaces.

The presence of surfaces in which ice crystals can also be essential. Trees, leaves, grass and other outdoor objects serve as anchor points so that ice crystals accumulate and create the characteristic cencellled layer. The way in which these crystals are distributed and grouped depends on the direction of the wind and other local factors.

The cencellate is distinguished from other similar phenomena, due to the fact that ice crystals are formed directly by the condensation of water vapor on the surface, without going through the liquid phase. This process can result in the creation of intricate and delicate patterns, often giving the cencellada a unique visual appearance.

Although the term “cencellada” is commonly used to describe the general phenomenon of ice formation on exposed surfaces, variations in the appearance and intensity of this phenomenon can be observed depending on the specific atmospheric conditions. Let’s see what are the main types of cencellled that exist, although there is no strict official classification of this phenomenon:

• Mild cencellada: It occurs in humidity conditions and temperatures close to the freezing point, but it may not be so visible or extensive. Although ice crystals are formed, they may not completely cover the surfaces, and the resulting layer can be thinner.
• Dense Cencelllada: Under more favorable atmospheric conditions, the cacelllada can be more intense, creating thicker and thicker ice layers. This usually occurs in environments where moisture is considerable and the temperature is just below the freezing point.
• Radial cencelllada: Sometimes, ice crystals can form more organized, creating radial patterns on affected surfaces. This type of cencellada can give the branches of the trees or the leaves a particularly picturesque appearance.
• ESPINOSA CENCELADA: Under special conditions, the cencellada can form ice crystals with more pointed edges, giving them a thorny appearance. This usually occurs when the cacelllada accumulates in smaller and pointed objects, such as grass or shrubs.
• Tangled cencellled: In areas with variable winds, the cencellada can be formed in a tangled and disorderly way. This results in more chaotic patterns and intertwined ice forms, especially when atmospheric conditions change rapidly.

Although cencellada and frost share similarities in terms of ice formation on exposed surfaces, there are key differences between these two meteorological phenomena.

• Training: The cencellada is formed directly by the freezing of the water vapor present in the air. Ice crystals are deposited on the exposed surfaces without going through the liquid phase, while the frost is formed when the water vapor in the air is condensed into liquid drops on the surfaces, and then these drops freeze, creating an ice layer.
• Temperature: The cencellate occurs in conditions close to the freezing point, usually with temperatures slightly below zero degrees Celsius. On the other hand, frost can be formed at lower temperatures than cencellada, even in more intense freezing conditions.
• Visual aspect: The cencellate tends to form more intricate and delicate patterns. Ice crystals are deposited more directly and can create finer and more complex structures. In the case of frost, it usually has a thicker and more uniform appearance. The resulting ice layer can be more robust and less elaborate compared to the cencellada.
