Why is there no wind in the center of the typhoon?

Typhoon center. called.

Eye of the typhoon. The eye of a typhoon is usually located within a circle with an average diameter of about 40 km at the center of the typhoon. Because the air on the periphery of the eye of the typhoon rotates too much, it is not easy for the outside air to enter the central area of the typhoon under the action of centrifugal force, so the eye area of the typhoon is like an isolated tube surrounded by a wall of clouds.

The air inside it is almost non-rotating, and the wind is weak. The area about 100 kilometers outside the eye of the typhoon is a storm area.

<> "Why there is no wind and rain in the center of the typhoon.

In China's coastal areas, typhoons are more or less hit by typhoons in summer and autumn almost every year, resulting in great losses of life and property. But, did you know that the typhoon's calm center is windless and rainless?

Within a circle with an average diameter of about 40 kilometers at the center of a typhoon, it is called the eye of the typhoon. Because the air on the periphery of the eye of the typhoon rotates too much, under the action of centrifugal force, it is not easy for the outside air to enter the central area of the typhoon, so the eye area of the typhoon is like an isolated tube surrounded by a wall of clouds, and the air inside it is almost non-rotating, and the wind is very weak.

Studies have shown that the air outside the eye area of the typhoon, swirling towards the center of low pressure, carries a large amount of water vapor, and because it is not easy to enter the eye area, it rises on its periphery, forming a large gray-black bloated and towering cloud, and it is raining like torrential rain. However, there is a downdraft in the eye area of the typhoon, so the clouds and rain dissipate, and twinkling stars can be seen at night.

As the satellite imagery of the typhoon shows, the eye of the typhoon is generally sunny to slightly cloudy, so it appears as a small black dot on the satellite image. But after the eye of the typhoon is removed, the weather will become extremely bad again. In the eye of a typhoon, many flocks of birds are often seen.

These seabirds, blown into the eye area of the typhoon by the typhoon's currents, find a "safe haven" and sometimes fly far away as the typhoon moves. Lack of mold.

Although the weather was good in the eye of the typhoon, the waves at sea were very rough because the pressure at the center of the typhoon was very low compared to the surrounding areas. Therefore, in the place where the typhoon center makes landfall, it often causes high waves and causes a lot of damage.

Due to the effect of the cyclone, the eye of the typhoon can be seen as a vacuum.

Moreover, a typhoon is a cyclone with a counterclockwise center of amplitude, and the wind blows towards the center, and the area in the eye of the storm is a downdraft, and the air pressure is higher than that of the nearby area, so why is there no wind or light wind in the eye of the typhoon?

I learned at the beginning of high school:

Because the pressure at the center of the typhoon is very low, the air on the periphery of the eye area is told to rotate, and the centrifugal force is large, causing the air to flow outward, and the air in the eye area is also flowing outward, so that there is a downdraft at the center of the center to supplement, so that the center of the typhoon forms a windy and calendar, clear and cloudless weather.

We usually say "maximum wind near the center of the typhoon" instead of "maximum wind near the center of the typhoon", because there is no wind in the center...

The center of the typhoon has the lowest air pressure and the outside pressure is high, resulting in a pressure difference, so the external convection forms a strong wind. The low pressure brings good weather, so there is no wind in the center, but it is sunny.

There is an error in what the West Building says, the eye of the storm is an updraft, and the air pressure is also the lowest in the entire storm system. However, since the rain clouds formed by the updraft are immediately transferred to the eye wall by strong centrifugal force, there is no wind and rain inside the eye of the storm. Only a relatively strong storm system can form an eye of the storm, while in a weak storm system, the centrifugal force is not strong enough, so the rain clouds will be trapped in the storm center, making the center area the place where the most precipitation occurs.

The horizontal distribution of various meteorological elements and weather phenomena in a typhoon can be divided into three areas: the outer cloud zone (including the outer cloud band and the inner cloud band), the cloud wall area and the typhoon eye area. The lead direction can be divided into three levels: the low-level inflow layer (about less than 1 km), the upper-air outflow layer (roughly more than 10 km), and the intermediate updraft layer (around 1 km to 10 km) (Figure 1). In the lower layer of the typhoon periphery, several spiral airflows with isobars in the typhoon area were involved in the typhoon area, and their convergence and rise promoted the development of the convective cloud system, forming the outer and inner cloud bands in the outer area of the typhoon. There are several spiral rain bands in the corresponding cloud system. At a certain distance from the center of the typhoon, the air flow no longer swirls, so a large amount of moist air is forced to rise strongly, forming a towering cloud wall around the center, and the top of the cumulonimbus cloud that constitutes the cloud wall can be as high as 19 kilometers, which is the Tuanling of the cloud wall area.

The maximum wind speed in a typhoon occurs on the inside of the cloud wall, and the maximum rainstorm occurs in the cloud wall area, so the cloud wall area is the most prone to disasters. When the updraft in the cloud wall area reaches the upper altitude, due to the weakening of the pressure gradient, a large amount of air is forced to be thrown outward, forming an outflow layer, and only a small part of the air flows inward into the typhoon center and sinks, resulting in a clear typhoon center, which is the typhoon eye area. The radius of the eye of the typhoon is about 10 70 km, with an average of about 25 km.

The latent heat release in the cloud wall area warms up and the subsidence warms in the eye area of the typhoon, making the typhoon a warm low-pressure system.

A typhoon is like your washing machine.

The pure spiral rain belt of the typhoon is like clothing.

The eye of the typhoon (the center of the typhoon) is the center of the rotating code washing pants dresser.

Because of centrifugal force, the center of the washing machine is hollow.

So, there was no wind in the center of the typhoon.

A typhoon is a large storm in the tropical ocean, and it is actually a large mass of rotating air that rotates and walks, and the air around it rotates sharply around its center. The faster the air rotates, the faster it flows and the greater the wind speed. However, in a circular area with a diameter of about 10 kilometers at the center of the typhoon (called the eye of the typhoon), the air on the periphery rotates too much, and it is difficult for the outside air to enter the inside, and it is like a large isolated tube.

Therefore, the air in the eye of the typhoon is almost non-rotating, so there is no wind.

Not only that, but the air around the center of the typhoon rotated counterclockwise around the center on the one hand, and on the other hand, it carried a large amount of water vapor with it, forming a large gray-black dense cloud cover, and it was pouring rain. In the eye of the typhoon, the air is sinking, so the clouds and rain dissipate, and there will be a temporary sunny day, and twinkling stars can be seen at night. It usually only takes 6 hours for the eye of the typhoon to pass, and then the weather becomes very bad again, and it is still a violent storm.

Although the wind is light and the sky is clear in the eye of the typhoon, the waves at sea are very dangerous. This is because the pressure at the center of the typhoon is very low compared to the surrounding area. In the place where the typhoon center landfalls, it often causes high waves, and along the coastal embankment, sometimes it also causes seawater inflow, causing great damage, so we must do a good job of typhoon prevention and flood prevention work in advance.

The weather is good in the eye of the typhoon.

The eye of the typhoon is located in the center of the typhoon vortex, occupying a circular well-shaped space from the ground to tens of thousands of meters in the air, with a diameter of several thousand meters to tens of kilometers, surrounded by a cloud wall of hundreds of kilometers to thousands of kilometers, which belongs to the area of violent storms. Because the air flow of the surrounding cloud wall rotates rapidly, the air outside the four sides is cut off, so that the air inside the four outside cannot enter the eye of the typhoon, so the air in the well-shaped eye of the typhoon remains as calm as stagnant water. And because there is an obvious downdraft from the wellhead, that is, the top of the eye of the typhoon, the airflow rises to form clouds, and the airflow sinking clouds disappear, so the rain in the eye of the typhoon disappears, and the weather is fine.

In the eye of a typhoon, due to the calm air, there is generally little harm to flying and navigation. The logbooks of many seagoing vessels record entering the eye of the typhoon. Flocks of birds are often found in the eye of a typhoon, and the thousands of seabirds that are blown into the center of the storm by the typhoon circulation find a "safe haven" in the eye of the typhoon, sometimes flying far away with the wind.
