Fire storms: What are they, how they form and risks

Fire storms are extreme phenomena that occur during great magnitude fires. They are characterized by the formation of a Self -sufficient fire, heat and wind systemin which the fire generates its own climate. This means that the intense heat of fire causes hot air to rush quickly, creating a kind of fireplace that sucks oxygen from nearby areas and further feeds the flames.

This type of storm can reach very high temperatures and cause unpredictable wind gusts that hinder any attempt to control by emergency equipment. At first glance, it may seem a more forest fire, but its behavior is much more violent, erratic and dangerous. In fact, sometimes it can even generate rotating rays or columns, known as “Torbellinos de Fuego”.

Fire storms do not arise spontaneously, but need a combination of specific factors to develop. Although its appearance may seem chaotic, its formation responds to certain environmental and terrain conditions that, by coinciding, trigger this extreme phenomenon.

Among the main causes of fire storms we have the following:

• One of the main causes is the presence of a Large fire and very high intensity. When the fire releases a massive amount of heat in a relatively concentrated area, hot air rises rapidly. This creates one strong ascending current That, in turn, causes an air vacuum near the ground, which generates winds that further feed the flames. It is like a self -sufficient cycle: more fire produces more heat, and more heat attracts more air and oxygen, which further fell fire.
• Another key factor is meteorology. Conditions like Very high temperatures, low humidity and dry winds and constants favor the formation of these extreme fires. The type of present vegetation also influences. If there are a lot of dry combustible material, such as leaves, branches or shrubs, the fire can spread faster and more intensity.
• The land can play an important role. The areas with pronounced earrings or narrow cannons They can channel the air and accelerate the wind, intensifying the fire. In these places, heat and smoke are trapped, which facilitates more energy at one point and increases the possibility of a fire storm.

The formation of a fire storm is a process that occurs in several stages. From A fire that has reached a Very high intensitythese are the stages:

1. Thermal energy release: It all starts when the fire releases a huge amount of thermal energy. That extreme heat causes the air on the fire to heat up quickly and ride hard, creating a powerful ascending current similar to that of a giant fireplace.
2. Training of the convective column: This hot air rises forms a vertical column known as a convective column. The stronger the fire, the higher and stable this column can be. When ascending, drag smoke, ashes, gases and shoes on. As the air rises, the space it leaves is filled with colder and rich in oxygen, which enters from the surroundings at high speed. This incoming air flow further feeds the fire, intensifying it and causing the column to become even more powerful. It is a cycle that is constantly feedback.
3. Creation of the pyrocumulonimbo: When the convective column is strong enough, it can pierce the stable atmosphere in upper layers and form a cloud known as pyrocumulonimbo. This cloud resembles a thunderstorm and, in fact, it can produce rays, thunder and rainfall, although these do not always manage to turn off the heat. On the contrary, the rays can generate new fires of fire several kilometers away.
4. Extreme phenomena and risks: In some cases, the intensity of the system can generate even more extreme phenomena, such as fire torbellins (small tornadoes with flames) or erratic winds that change direction without prior notice. These characteristics make fire storms a true challenge for firefighters and civil protection equipment, since their behavior is unpredictable and very dangerous.

This is nothing more and nothing less than one of the most dangerous phenomena related to fires, not only because of their intensity, but also for its unpredictability and destructive capacity. The risks they generate are multiple and affect both people and infrastructure, ecosystems and the emergency equipment themselves.

• One of the greatest dangers is speed with which the fire can spread. Due to the violent winds that are generated around the fire column, the flames can advance in different directions without warning, overcoming firewalls and jumping natural or artificial barriers easily. This seriously complicates evacuation tasks and can catch people or vehicles in minutes.
• In addition, the extreme temperatures They are reached in a fire storm (often above 1,000 ° C) they are capable of destroying entire structures, melt materials and consuming large extensions of vegetation in a short time. Bosques and burning particles transported by the wind can light new fire spotlights several kilometers away, which makes the fire front even more unpredictable.
• Another important risk is the formation of Dry raysgenerated by the clouds that accompany these storms. These rays usually fall on not affected areas and trigger new fires, expanding the scope of the catastrophe.
• For the Extinction teamsface a storm of fire is extremely risky. Sudden changes in the wind, low visibility for smoke, unbearable heat and the lack of safe points to maneuver endanger their lives constantly. Even with specialized teams and training, they often must withdraw and let fire progress, prioritizing people’s safety.
• They also exist long -term risks such as the destruction of natural habitats, the loss of biodiversity, the mass emission of polluting gases and soil degradation, which can favor erosion and hinder ecosystem recovery.
