Today, we will use a scientific perspective to explore the complex truth behind meteorological events. According to the latest news from the American Fox News website, at around 16:33 local time on the afternoon of Wednesday, January 3, the tranquility of Notre Dame de Wavre in the Antwerp Province of Belgium was broken by

A serious incident. The tornado struck the area causing severe damage in its wake . It left a trail of violent destruction in its wake. Trees were uprooted , buildings were damaged and debris was scattered across the area. Later that day in Belgium, between St. Catherine, Weaver and Putte

The tornado that occurred recently caused serious damage and left a trail of destruction that stretched for 4 kilometers. The local police district confirmed that the tornado ripped off the roofs of houses within an area of ​​approximately 4 kilometers and destroyed a large greenhouse. Some sheds were also blown to pieces at Putt Cemetery.

A total of 40 houses were also damaged , two of which have been declared uninhabitable. Residents found shelter with relatives on Wednesday night . Fire brigade managed to once again secure buildings in most areas. Local police urged to avoid WAVs . There were many vehicles damaged in the area around Saint Catherine.

The municipality of Wavre Saint Catherine reported that roofs were torn and rubble was scattered throughout the area, affecting about 40 houses , two of which are now uninhabitable . Thank you for your likes. Leave a comment, subscribe and turn on the bell. We have daily updates. Large amounts of glass and debris

Were scattered along bike paths and driveways in the Putte area of ​​Belgium, but technical services in Putte cleared it later in the evening . The police district further measured the damage during the day and Take necessary action. Among the worst affected were local growers. One of the growers, Paulanco, suffered severe losses, destroying

40 years of cultivation in just a few minutes . The grower Paul’s wife, Agnes, confirmed that a greenhouse was completely destroyed. The destroyed structure collapsed badly with widespread glass shattering. While grower Paulanco was the worst-affected gardening company, the tornado’s impact varied. Some nearby greenhouses escaped unscathed, highlighting the localized nature of the damage.

Rescue workers and insurance companies moved in the next day . But the dangers of falling glass and structural instability make repairs and cleanup difficult in five northern French departments of Aisne, Ardennes, Meuse and Meurthe-Moselle, located on the border with Belgium. It is under an orange alert for water overflows. Belgian meteorologists confirmed that

The extreme weather in the north of Antwerp was a tornado. This is relatively rare in Belgium . Recently, extreme weather has occurred frequently in Europe . We have tracked and reported tornado events in many countries. On November 21 We once reported on a series of tornadoes in Italy

In Japan. At that time, tornadoes struck the mainland more than a dozen times from the sea. This dangerous and spectacular scene frightened many residents. The rugged rocks and picturesque coves are located on the Amalfi Coast south of Naples . One of Italy’s most fascinating tourist attractions

. According to records, 15 to 20 such huge waterspouts occurred in this small town that afternoon. About 12 of them are said to have reached the coast , including the Amalfi Coast. Naples is the capital of the province. For the second time that day, a waterspout was filmed

Forming in the waters near the port city of Salerno. A powerful, towering whirlpool could be seen spinning toward coastal communities. Local tourists ignored the opportunity to take photos and check in with their mobile phones. Recording this spectacular scene, there have been many tornadoes in Italy in recent months , one of which

Ravaged between Maiori and Capo d’Orso. Local media reported that it was very lucky that there were no houses near the land. Then Sasa The people of Lenoir were shivering in front of the tornado . Fortunately, the tornado stopped right in front of the port. If it had continued deeper inland,

I believe it would have caused unimaginable damage and losses. Videos of the tornado have been circulating on social media, causing widespread discussion about extreme weather. It also frightens local residents. Some countries around the world are frequently hit by tornadoes due to their special geographical features. The first is

The Great Plains in the central United States, which is known as the “Tornado Trail.” Tornadoes occur frequently in spring and summer. This area is located in the Gulf of Mexico. Extreme weather is prone to occur at the intersection of warm and humid air and northern cold currents . The

United States ranks first in the world in terms of absolute losses and casualties in tornado disasters , followed by Bangladesh. The low-lying northern part of the country has hundreds of years of tornado records. Affected by the terrain, most of them are strong T6. Level and above are also due to dense population.

Each disaster causes a large number of casualties. At the same time, Northeast Japan and offshore islands are also the main prone areas. In recent years, the incidence rate of tornadoes nationwide has increased significantly . Northeastern areas account for about 65%. Most tornadoes in Japan usually

Last for a short time, but The destructive power is high. In addition, tornadoes often occur in areas such as the Ganges Plain in northern India. Among them, Uttar Pradesh, Bihar and other populous provinces are the most severely affected. Tornadoes in India mostly occur during the warm-up thunderstorm period from March to May, which

Cannot be ignored. Canada is similar to its neighboring United States. Southern Canada and other places also experience frequent tornadoes, which are a major threat to provinces such as Ontario and Saskatchewan. The number of tornadoes in eastern Canada is smaller but more destructive. It is worth mentioning that

The Central Siberian Plain of Russia is Regional tornadoes or dust devils often occur in the region . Tornadoes are mostly caused in June and July due to poor infrastructure, and disaster losses are large . It is worth noting that the northeastern plains of Pakistan are also under the influence of

Monsoons and residual tropical cyclones. The weather that can induce tornadoes usually occurs from March to October. Most of them occur suddenly between the evening and midnight. What is more special is the occasional cirrus clouds in southeastern Australia . The most typical

Ones are in northern Queensland. Most of the tornadoes are storm level or moderate. In terms of scale, in South America, the central plains of Argentina are also scattered with tornado-prone areas. Local tornadoes are mainly in spring and summer, and they are difficult to distinguish from dust storms

. In fact, the formation mechanism of tornadoes is relatively complex. First, the formation of tornadoes requires obvious differences in aerodynamic conditions. Stability provides “fuel” usually in the spring and summer when the land warms faster than the ocean. The air mass over the continent is warmer while the air from the ocean remains cooler.

When the temperature difference reaches more than 10 degrees Celsius, instability is generated in the lower levels. This is a strong The development of updrafts creates conditions. Secondly, forced upward motion is the second key factor in the generation of tornadoes . Updrafts mainly come from two aspects:

First, wind shear generated by the large central mountains of North America. These towering mountains force westerly winds to rise sharply; second, developed The storm zone and the strong convective updrafts it generates are the most direct driving force. These airflows will produce rotational motion during the ascent.

In addition, the presence of high wind shear is also extremely important in tornado areas. Near-surface wind speeds are slower but high-altitude jet wind speeds can exceed 150 kilometers per hour. This strong vertical wind shear will generate and amplify vorticity and promote vortex funnels. The location and intensity of the generated wind shear

Are crucial to the formation of a tornado . Therefore, under the combined effect of the above complex mechanisms, if the rotating funnel is strong enough to extend to the ground and accompanied by extreme pressure changes and buoyancy effects, it will produce extremely destructive tornadoes. The entire process of a tornado

From the clouds to the ground only takes a few minutes. Generally speaking, the areas that are often hit and damaged by tornadoes are mainly concentrated in areas with relatively similar geographical features. The first is the inland plain or basin terrain, the Great Plains of the Central United States, the Eastern European Plains,

Etc. Areas with open terrain and no barriers of mountains and rivers can easily become areas where tornadoes choose to land and wreak havoc. The intersection of warm and humid air in spring and summer with the cold current from the north provides dynamic conditions for the generation of tornadoes.

Secondly, inland areas near large water bodies or oceans In areas such as the south-central United States facing the Gulf of Mexico and the north side of the Bay of Bengal, the continuous water vapor transport provided by large water bodies will make the air more unstable.

The local circulation caused by the temperature difference between the sea and the land can also easily become a “trigger” for tornadoes. More importantly, the basin and the The mountain ranges in the mountainous areas produce vertical shear of air flow and cause the convergence and transport of air masses between valleys, exacerbating convective instability.

These terrain edges are exactly the areas with high incidence of tornadoes. It should be noted that the above three types of geographical features often have compound superposition, which is extremely serious. The risk of regional tornado disasters has been greatly enhanced. They are tornado “hot spots” in terms of disaster records and meteorological mechanisms

. It is very important to take timely evacuation measures when a tornado occurs. First, you must take shelter in a pre-identified shelter. For most ordinary houses, basement bunkers or sunken garages are the best places to take refuge. First, most of these locations are on the ground. The following

Are helpful for avoiding external splashes. Secondly , the cement walls among them can also withstand the impact of flying objects produced by some tornadoes. You need to confirm in advance which buildings around your community or work area have such shelters and enter the shelter as soon as possible before the tornado strikes.

Keep your doors and entrances in good condition and wait for the storm to pass. In addition, the underground spaces of some specific public buildings such as schools, gymnasiums, and subway stations can also be used as evacuation points . Secondly, take shelter in low-lying areas. If you cannot escape in time , seek shelter

In the building. Use natural barriers such as low-lying ravines, mountain depressions or behind roadside retaining walls. Then choose a location away from large trees, telephone poles and other places that may produce flying objects. Lie down and curl up to protect your head and neck with your hands

To reduce direct exposure of your body. If you have a coat, blanket, etc., you can also cover yourself to cushion the impact . Wait for the tornado to completely pass through before leaving . During the evacuation process, pay attention to the risks of secondary disasters such as floods, mudslides, etc.

Around you . In addition, be alert to surrounding danger sources , whether you are inside a building or taking shelter on the spot. Be fully aware of and stay away from surrounding collapse risk points. If you are in the woods, pay attention to large trees that may break overhead.

When approaching telephone poles and street signs, be aware of the possibility of them collapsing towards you after being hit by a tornado. In addition , pay attention to the glass windows inside the building. , keep a certain distance from the door to avoid being scratched by the broken glass after the storm damage.

It cannot be ignored that you must take a safe way to escape while driving. If you are driving , do not try to “race” with the tornado. When facing strong winds, you should slow down your vehicle, pull over to the side of the road , and quickly seek

Refuge in a roadside building or under an overpass. If you really cannot find shelter , you should fasten your seat belt and cover your head and potentially exposed parts of your body with blankets and clothing. Also be careful of secondary disasters such as deep water accumulation and landslides. It is worth mentioning that

You should pay attention to the risk of water accumulation in low-lying areas such as rivers and under bridges . Tornadoes are often accompanied by heavy rain or thunderstorms , so low-lying areas such as river banks, lakesides, downstream of dams , and bridge openings The

Water level is likely to surge in a short period of time. If you are trapped near these locations, you must evacuate to a higher and safer place in advance to avoid drowning accidents . Generally speaking, tornado protection must follow certain architectural design principles. First,

Pay attention to the building structure. The concrete and steel structure skeleton is chosen for its own wind-resistant performance as the backbone of the wind-proof structure. The walls of the structure must be thick enough . The steel bars and connectors must be strong to ensure that the whole can withstand strong external impacts

. In addition, indoor supports such as beams and diagonal braces should be designed to enhance the rigidity of the building against wind pressure. The overall structure should also be symmetrical and concise to reduce the area of ​​air vents. Secondly,

We should make good use of the windproof partition function of large bay doors and windows . Use double-layer or three-layer hollow glass curtain walls and install windproof roller shutters or steel plates on both sides of the indoor and outdoor areas to close and fix the hollow layer before the storm approaches.

Leave appropriate space to buffer wind pressure shock waves. Glass surface treatment can also enhance bulletproof and crack-proof performance. More importantly, pay attention to the windproof and fine design of the roof structure. The overall roof should not be too complex and changeable to avoid becoming a wind outlet.

Use a single inclined surface, simple and streamlined waterproofing The pavement of floors and truss layers must be firm. Light steel, stone fiber board, etc. are preferred as roof materials . Air ducts, skylights, and landscape protrusions must be converged and simplified to reduce wind capture points. What cannot be ignored

Is the protective interference of underground spaces and bunkers. It is worth mentioning that the one or two underground floors of the building should be appropriately increased in area and reserved for daily use for long-term shelter. The walls should be strong, the entrances and exits

Should be windproof and waterproof, and necessary supporting facilities such as ventilation and lighting should be complete , and an independent power supply system should be preset to prevent power outages. The most important thing is to pay attention to the windproof design in the surrounding environment of the building.

Distribution lines are buried underground and pipes are added with windproof joints; windbreak forest belts are planted and wind-resistant tree species are selected; windbreak walls and flower beds are added to increase surface roughness to slow down the wind speed . Rooftop landscaping is also effective. Wind protection and deceleration effect

. In addition, urban planning in areas with high tornado incidence should also follow necessary disaster prevention principles. First, the functional zoning layout should adopt a decentralized and staggered pattern. Industrial areas, commercial areas, residential areas, etc. should not be too concentrated or long. Such an arrangement is likely to produce huge wind vents.

Urban park green spaces of a certain width should be set up between each functional area to buffer and reduce wind and facilitate the evacuation of people. Secondly, the urban road network should be designed into a high-density grid and the road width should be consistent with

The block scale . Control it within 300-500 meters, which is very important for the rapid evacuation of people and vehicles when a storm strikes. Main roads should be elevated or overcut to prevent local water accumulation. More importantly, high-rise buildings and important facilities should be kept away from the edge of the city

In terms of building layout. To prevent the windward side from being hit by strong impacts, low-rise simple buildings are arranged around the perimeter to regulate the wind environment at the urban boundary. High-rise buildings can be appropriately arranged in the central area to avoid strong wind fields on the top floor.

It is worth mentioning that all types of tornado public shelters must be reasonably and adequately laid out. Focus on covering densely populated areas and integrate them into the ground wind protection guidance system Such as signs, guide boards, etc., windproof partitions, backup power supply and other supporting facilities in these places

Should not be ignored. It cannot be ignored that a certain proportion of open natural patterns such as wetlands and woodlands should be retained or restored in the surrounding areas of the city, which can play a buffering role against tornadoes and can significantly slow down tornadoes. Wind field speed and vortex intensity

Are natural barriers to tornado defense. At present, it is necessary to take special preventive measures against tornado disasters in key areas . First of all, it is necessary to strengthen meteorological monitoring and early warning. The use of multi-point weather radar monitoring and sounding balloon wind measurement

Can be more effective. Detect the emergence of tornadoes early and cooperate with big data analysis to achieve accurate prediction of extreme weather and risk zoning to gain 1-6 hours of valuable preparation time for disaster prevention. Secondly, the disaster prevention and evacuation system must be improved.

Governments at all levels must work with communities to comprehensively identify basements. Tornado evacuation sites such as subway stations and gymnasiums should calculate the number of people they can accommodate. Install independent power supplies and communication facilities. Reserve certain living supplies . Develop detailed disaster response plans and provide in-depth education. At the same time,

The wind resistance of the infrastructure must be strengthened. Telephone poles and street signs must be selected. The ground parts of lightweight materials are strengthened and anchored . Civil buildings must fully adopt the design concept of wind prevention and disaster reduction. From the location layout, spatial structure to door, window and wall materials and

Other details, the wind resistance level is improved. Major public buildings reach the highest wind protection standards . Thank you for liking, leaving a message, and subscribing. And turn on the little bell and we will update the latest news from around the world every day
