Typhoons are so destructive, why are they safe in the eyes of typhoons?

Typhoon is a very common natural disaster in the coastal areas of our country, although the typhoon is not so destructive, but when the typhoon comes, it can also cause great economic losses and personnel, especially the super typhoon above 16, everywhere is basically "looted", but fortunately, the movement of the typhoon is very large, people can use the current scientific and technological equipment to find them early, and take preventive measures in advance, so as to avoid economic losses and personnel to the greatest extent. Friends who have seen the typhoon forecast know that the typhoon is like a huge spiral on the map, and there will be a typhoon eye in the center of the typhoon, just like the center of the tornado, and there is generally no wind in the center of the typhoon eye, and there will be no dark clouds, which is relatively safe, which can't help but make us wonder, why is the typhoon so destructive, but the typhoon eye is very safe? After reading the knowledge.

It turns out that the destructive power of the typhoon periphery is very strong, and there is a strong air flow on the periphery of the typhoon, and the more the air flow goes to the center, the smaller it becomes, and finally there is basically no wind in the eye of the typhoon, so we often see the news that there are birds in the eye of the typhoon, and these birds may be swept in by the typhoon air flow and trapped in the eye of the typhoon within a radius of several kilometers or more than ten kilometers. But they can still fly freely in the center of the eye of the typhoon, and there is no wind in the eye of the typhoon, and there is no thunder or rain, so why is that? In fact, the answer is very simple, to put it simply, centrifugal force is at work, when the typhoon is formed, it is surrounded by strong air currents, these air currents rotate around the center of the typhoon, and under the effect of strong centrifugal force, the peripheral air flow is strong, but there is no wind in the middle and medium, so theoretically speaking, people will be very safe inside.

But from a realistic point of view, it is impossible for people to enter the center of the eye of the typhoon, unless you are swept into the air by the typhoon and then thrown into the eye of the typhoon and are still alive, and you have to move with the eye of the typhoon to ensure safety, this situation generally only appears in science fiction movies, so this security can only be in quotation marks, theoretically safe, and there will even be a small sunny day in the center of the eye of the typhoon.

In the end, the principal believes that the destructive power of typhoons is very great, but the formation of typhoons began with tropical cyclones, tropical cyclones continue to advance on the sea surface, and all the surrounding air currents are sucked in, and finally a typhoon with strong destructive power is formed, but fortunately, typhoons are not as unable, the formation of typhoons has very distinctive characteristics, as long as our instruments are not bad, we can monitor the development of typhoons in real time, but we can not underestimate typhoons, in the coastal zone of our country, we will encounter many typhoons every year, The economic losses and personnel caused are not small, so everyone must take shelter in time when encountering a typhoon.

Typhoons are destructive only because the winds in the outer ring of the typhoon are strong enough to destroy many objects. However, there is no wind in the middle of the eye of the typhoon, but the temperature is very low, and if you can withstand the cold, then the eye of the typhoon is indeed "safer" than the outside of the eye of the typhoon.

Because of the effect of centrifugal force, the strong air flow around the typhoon rotates around the center of the typhoon, and under the action of strong centrifugal force, there is no wind in the eye of the typhoon, so theoretically speaking, people are still very safe in the eye of the typhoon.

Because the typhoon is spiral-shaped, and there is no wind in the middle, it is very "safe" in the eye of the typhoon.

Because in the process of typhoon formation, it is constantly swept by external forces. Relatively speaking, there is no danger in the eyes of typhoons.

Are typhoons scary? Thinking about how harmful a typhoon is? Can you imagine? Unthinkable? So let's talk about this topic and talk about what is his harm? Where is his terrible place? <>

Everyone has heard of typhoons, for example, a news report mentions that a certain typhoon occurred in a certain place, and so on. The frequency of typhoons is higher in some places and lower in others, depending on the topography and other factors of the location. <>

The dangers of typhoons are very great. It is bound to cause property damage, loss of goods, damage to plants, damage to small animals, and even loss of personal life. For example, a certain typhoon completes the destruction of goods and completes personal interests; Damage to plants not only destroys the human characteristics, but also destroys the natural environment, and also causes serious environmental damage in the location, air pollution, people can not breathe fresh air, and the water they drink will be unclean, bringing unimaginable consequences to human beings; Typhoons can also destroy vegetation in the area, destroy crops, lose yield, or even lose all yield; A severe typhoon can cause loss of life to people, and even involve people in it, and if they cannot escape, they will lose their own lives.

Do you want to hear if you are afraid of typhoons? Do you get scared and shiver at the mention of typhoons? Will it be unresponsive?

In fact, typhoons are very scary, even if they will lose some yield, destroy vegetation, damage animals, these are secondary, the most important thing is that it will lose human life! Some benefits will be lost, and some people will even leave no family property, and the typhoon will sweep away all the benefits. What we can do is to protect the vegetation, to do some protective measures in line with the local weather and topography, so that we can minimize the frequency and frequency of typhoons, and this is what we can do.

It is particularly terrible, there are particularly serious hazards, it will lead to particularly serious economic losses, it will damage buildings, it will affect human life, it will cause the temperature to get lower and lower, and it will cause particularly serious natural disasters.

It can destroy our homes, it can endanger our lives, it can destroy farmland, it can bring us very big disasters, and people's lives are not guaranteed. It is very scary, because the typhoon is very big, and some unexpected situations can easily happen on typhoon days.

When a typhoon passes, sometimes large trees are uprooted and roofs can be blown off by the wind. The wind was accompanied by torrential rains, which poured water on the ground in a short period of time to flood crops, destroy houses, and even disrupt transportation, forcing some factories to shut down. Typhoons on the sea are more vicious than those on the ground, setting off monstrous waves and threatening the lives of ships sailing on the sea and those engaged in fishing, aquaculture, exploration, oil extraction and other operations.

Typhoons are catastrophic weather that can cause great disasters to people.

Typhoons are very harmful, affecting the local economic development, destroying some buildings and blowing down some crops. It can also bring serious disasters to people. Typhoons are very scary, and the power of typhoons is very great.

Stepping on thousands of rivers, raising the sand in the sky, startling the birds in the forest and breaking the flowers in the garden. This is often described as a "typhoon". Typhoons are very destructive, and they are generally formed in the ocean, so when you step on thousands of rivers, you will roll up dirt and trees, and destroy facilities such as houses, gardens, and roads, so you can raise sand all over the sky, startle the birds in the forest, and break the flowers in the garden.

A typhoon is actually a severe tropical cyclone that requires at least two conditions to form, namely high temperatures and abundant moisture.

For example, when you boil water, the water at the bottom of the pot will rise because the water at the bottom of the pot expands when heated. The same is true of air, when the air at the bottom is heated, it will rise. At this time, the outer air of the rising area continues to flow into the rising area, and due to the rotation of the earth, the incoming air rotates like a wheel, which is the cause of typhoons.

When the rising air expands and cools, the water vapor in it cools and condenses into water droplets, which releases heat, which in turn promotes the continuous rise of the bottom air, so that the air pressure drop on the ground is lower, and the air rotates more violently, so that a typhoon is formed.

Although the speed of these typhoons is not fast, the wind speed inside is very fast, and the impact of this typhoon is also very serious, and in order to do a good job of corresponding preventive measures, the local authorities should strengthen the prevention and control management in this regard.

After the formation of a typhoon, the air pressure near its center is low and the wind speed is high, and the strong pressure brought by the typhoon can blow to houses, uproot large trees, fly sand and rocks, and harm people and animals.

Natural typhoons generally make landfall in the coastal area, and if it lands above level 12 for a strong typhoon, everything within the landing area: agriculture, forestry, animal husbandry and fish will be directly damaged.

2. Houses, embankments, roads, landslides, ponds, and reservoirs are all directly damaged. Therefore, before the typhoon makes landfall, it is necessary to do all the disaster prevention work, evacuate the people in serious cases, and try to minimize the losses.

Typhoons are natural disasters, and as long as the wind is strong and the damage is great, all kinds of hazards are possible. Lekima is the strongest typhoon of 2019 so far, and the damage to residents** and the economy has long been far greater than that of Telly at that time. Let's take an analogy.

If the wind reaches force 12, it can throw hundreds of tonnage ** onshore ......Well, that's it. At present, the wind force in Limache is 16 in the center of the sea, and it will be landed at about 2 o'clock in the middle of the night, and hopefully, the wind will be less than 12 by then. Otherwise, ......

In fact, the essence is the same, but the name is different. The name hurricane** is derived from the Caribbean word hurican, which means demon. The name "Typhoon** comes from Greece, Typhon, the son of Gaia, Mother Earth.

Until now, the names of typhoons have been conventional, one name for another, not just for us, and the names here are all based on the joint name of the affected countries, and sometimes you see that the typhoon that makes landfall has its own name.

It's hard to imagine how terrible a typhoon is, you can compare it to **, but a typhoon is at most just something that destroys the ground, and it can't go deep into the ground, and ** will seep into the ground. Tornadoes or typhoons will come with extremely strong precipitation and wind, these winds will damage buildings along the way, fallen trees will seriously block traffic, the collapse of buildings will affect the safety of people's property, many rescuers are also involved in the rescue after the typhoon. It is to lower the calculation and restore people's normal life.

The destructive power is very strong, because it is a natural disaster formed from the sea, and we have no way to resist it.

The destructive power is still very strong, and this kind of natural disaster is an indiscriminate attack, which will cause great economic losses.

The destructive power is very strong, and the typhoon will also cause relatively large pollution to the environment, which will cause very large losses, so it is best not to go out during the typhoon weather.

It is especially strong because typhoons can destroy a lot of buildings, and there is a high probability that they will blow away a lot of things at any time.

It is particularly large, it is easy to cause a tsunami, and it is easy to cause people to fall, it is easy to cause people to be injured, property is damaged, and it can cause the ship to capsize while sailing in the sea.

It is very large, which may cause the collapse of the house, and at the same time, it will also cause a lot of hazards and accidents.

Typhoons are a destructive and harmful natural phenomenon. Before the arrival of the typhoon, we should pay attention to the typhoon disastrous weather warning information announced by various meteorological stations, and make corresponding preparations in advance. When a typhoon hits, avoid going out as much as possible, avoid low-lying areas and risk areas such as seashores, and risk equipment or items such as trees and billboards.

So, how do typhoons with extreme weather occur? A typhoon is a tropical cyclone that transforms over a tropical ocean.

How typhoons produce direct sunlight over the course of a day, producing strong cumulonimbus clouds at sea level. The hot air in this cumulonimbus cloud rises, and the colder air around it is continuously filled in, and the heat rises again, so that the air above is hot and the air below is cold. The evaporation of water vapor from the hot air above expands the cloud band, and the cloud band expansion makes this type of fitness exercise more intense.

Evolving clouds are affected by geostrophic deflection forces and turn in the opposite direction (clockwise in the Eastern Hemisphere), producing tropical cyclones. The centripetal force caused by the rotating air in a tropical cyclone throws the air outward, and the air in the center becomes thinner and thinner, and the working pressure of the air continues to decrease, resulting in a tropical depression - the original link of the typhoon.

Since the central standard pressure of the tropical depression is lower than that of the outside, the surrounding air rushes into the tropical depression and is heated up, providing more kinetic energy from the tropical depression than the output kinetic energy. At this time, the air rotation in the tropical depression is stronger, the wind speed of the center increases, and the central standard pressure decreases further. Until the wind speed in the center reaches a certain standard, it will be raised to a higher level, that is, the tropical depression will be raised to a strong tropical storm, and then to a strong tropical storm, a typhoon, and sometimes a strong typhoon or even a strong typhoon.

The key to this is determined by the ratio of kinetic energy input to output, and if the kinetic energy of input exceeds the output kinetic energy, the typhoon will increase, and vice versa. Typhoons are a destructive and harmful natural phenomenon.

The conditions for the formation of typhoons can be seen from the typhoon structure, and such a great leader must have a unique standard for its cause:

It is necessary to have a wide area of high temperature, high and low temperature air. The temperature and ambient humidity of the bottom air on the tropical ocean surface are determined by the sea level temperature, and typhoons can only occur on the warm ocean surface where the sea surface temperature is higher than 26 -27, and the sea surface temperature at a depth of 60 meters needs to be higher than 26 -27.

There should be a primitive oscillation of the low-rise air converging towards the center and the high-rise residential diffuse. In addition, the divergence of high-rise residential buildings must exceed the convergence of the low layer, so as to maintain sufficient updraft, and the low layer oscillation can be vigorously strengthened.

The vertical wind force should not differ too much, and the relative velocity of the upper and lower layers of air should not be large, so that the vaporization heat energy released by the condensation of water vapor in the original oscillation can be stored in the air column in the eye area of the typhoon, so as to generate and improve the structure of the typhoon warm center.

It is necessary to have a sufficiently large geostrophic deflection effect, and the earth's rotation effect is beneficial to the transformation of airflow eddies. The geostrophic deflection force is close to zero around the Earth's equator and expands to the north and south, and typhoons occur over the ocean about five levels above the Earth's equator.
