Black frost: what is, temperature and consequences

A black frost is a meteorological phenomenon that occurs when Temperatures fall enough to freeze plants tissuesbut they don’t do it with the water present in them. In these frosts plants may seem intact on the outside, but in reality they are damaged inside due to the freezing of internal fluids. Although at the beginning it may seem that the plant is fine on the outside, as time passes with black frost, the plant ends up seeing badly externally and dying. This type of frost is particularly harmful to crops, since it can cause the death of plants or seriously affect their ability to grow and produce.

The exact temperature in which a black frost occurs can vary depending on various factors, such as the relative humidity of the air, the presence of wind and the duration of the cold period. However, it usually occurs when temperatures descend Below the 0 ºCalthough they do not necessarily reach extremely low values. It usually happens in temperate and subtropical climates during certain times of the year, especially during spring and autumn, when temperatures can fluctuate sharply.

These are the most common types of frosts that exist:

• White frost: This is the most common type of frost and occurs when temperatures descend below the freezing point and dew freezes on the surface of plants and other objects.
• Radiation frost: This type of frost is produced in clear sky and calm wind at night. When the earth loses heat quickly by radiation, the layers of air close to the surface cool, which can cause frost formation and frost in vegetation.
• Section frost: This frost occurs when a mass of cold air moves over a warmer and more humid region, cooling the surface and causing the freezing of plants. The monting frost can occur in coastal areas or in regions where cold winds blow from colder areas to warmer areas.
• Thermal investment frost: This type of frost occurs when a cold air layer is formed near the surface while a warmer layer is above. This thermal investment prevents cold air from mixing with the warmest air, which can result in very low temperatures near the ground and frost formation.

The consequences of a black frost are significant and varied, affecting both agriculture and the environment in general. Can cause Serious damage to cropsespecially those who are sensitive to cold. The affected plants experience the death of tissues, which results in the leaves wither, the fruits decompose and, therefore, the growth and production of the crop is reduced. In some cases, Plants can diewhich, in the case of crops, entails significant economic losses for farmers.

Black frosts They affect the availability and price of foodespecially if damaged crops are important for human or animal food. This may have repercussions on food security at local, regional and even national level, especially in areas where food is scarce or where agriculture is vulnerable to extreme climatic conditions.

In addition to affecting crops, black frosts also have an impact on the environment in general. For example, They affect natural vegetation and reduce biodiversity In the affected ecosystems.

Black frosts are a climatic phenomenon that affects various regions of Spain, especially in those areas where agriculture is an important economic activity. Although Spain is known for its tempered climate in many areas, certain regions may experience climatic conditions that favor the formation of black frosts, especially during the coldest months of the year.

In Spain, black frosts are especially harmful in areas such as The interior of the Iberian Peninsulawhere temperatures can descend significantly during the night, especially in mountain areas and valleys. In addition, areas with a Continental or Mediterranean climate They are more susceptible to the formation of black frosts due to the combination of cold temperatures and a low relative humidity.

The crops most affected by black frosts in Spain are usually fruit trees, such as citrus, olive trees and almond treesas well as The vineyards. These plantations are particularly sensitive to cold and suffer serious damage if they are affected by a black frost.

To deal with black frosts, farmers in Spain usually resort to preventive measures such as sprinkler irrigation to protect crops, the use of heating systems and the installation of cold protection devices.

The main difference between a black frost and a white ice cream lies in the effect they have on plants and how they occur.

• A Black frost occurs when temperatures descend enough to Freeze the internal fabrics of plantsbut they do not freeze the water present in them. This means that plants may seem intact on the outside, but in reality they are damaged inside.
• On the other hand, a White frost It is a more common phenomenon that occurs when temperatures descend below the freezing point and Rocío freezes on the surface of the plants and other objects. Here you can learn better: what is and how it occurs. Unlike black frost, white frost Does not penetrate plants tissuesbut it can causer External damagesuch as the burning of leaves and flowers. The white frost is usually more visible, since it forms a visible ice layer on the exposed surfaces, which facilitates its detection.
