The destructive power of a typhoon is frightening, so why is it calm at the eye of the typhoon ?

Sports is important to us, sportsmanship is even more valuable, in strengthening the body to bring you the strength of the limbs at the same time, but also to enrich your heart, enrich your personal life, let us promote sports, the development of sportsmanship.

Causes

Because the air on the periphery of the eye of the typhoon rotates too much, it is difficult for the outside air to enter the eye area under the action of centrifugal force, so the eye area looks like a large isolated tube surrounded by a cloud wall. The air inside is almost non-rotating, the wind is very weak, and the clouds are often few or no clouds.

Typical featuresIn the middle of a mature tropical cyclone (a tropical storm or higher), there is often a clear sky with a diameter of several tens of kilometers and an approximately circular area with few clouds, called the eye area. On the satellite image, the eye area appears as a large black dot near the center of the dense cloud area. A ring of clouds around the periphery of the eye area is called a cloud wall or eye wall.

The eye area is usually round, but also oval or irregularly shaped, and when a tropical cyclone develops at the beginning, the eye area is generally irregular in shape and has a large range. When a tropical cyclone develops strongly, the eye area shrinks into a circular and axisymmetric distribution.

The power of the typhoon is extremely fierce, why is it calm at the eye of the storm? 3D animation explains the principle.

Because it is true that the more you go to the eye of the storm, the calmer it becomes, and it itself belongs to the vacuum zone.

Because this is the calm before the storm, and when the typhoon comes, it will be calm.

The typhoon eye is calm, in fact, because of its special structure.

Because the typhoon rotates the surrounding air, and the place in the eye of the typhoon happens to be without wind.

Then I think it's a special reason, I think it's because of the vortex it formed.

Because the eye of the storm is a vacuum zone for typhoons, it will be calm.

A typhoon is a strong cyclonic storm, due to the existence of cyclonic nature, the airflow at the eye of the typhoon is downward, that is, the surrounding airflow will converge to the center of the eye of the storm, forming a relatively quiet environment, so that the sky is calm at the eye of the typhoon.

In the center of the eye of the typhoon, the direction of rotation of the air flow is opposite to the direction of rotation of the typhoon as a whole, and the air in the center of the cyclonic storm falls, and this sinking air is also released outward, creating an area with lower wind speed and less precipitation, which is also known as the eye of the typhoon. Because the air flow around the eye of the typhoon converges inside the eye of the storm and moves downward, the air pressure in the center of the eye is relatively low, but the wind speed is relatively small, so the wind is calm.

It should be noted that the environment inside the eye of the typhoon is relatively quiet, but around the eye of the storm, the intensity of the typhoon storm will be more intense, and the wind speed and rainfall will be greater. Therefore, before the typhoon comes, the reeds in the human cave should take the necessary measures to prepare for wind and disaster prevention.

Summary: 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 air outside the eye area of the typhoon swirls towards the center of low pressure, and it carries a large amount of water vapor, which is not easy to enter the eye area, and rises and rots on its periphery, forming a large gray-black bloated and towering cloud, which is pouring 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.

Closed eye area:The occlusive ocular area is the ocular area of the peripheral ocular area with a single-layer structure and an intermittent angle of less than 90°. Combined with the condition of the peripheral eye wall, the closed eye area can be further divided into three state leak subcategories: round eye, round eye and polygonal eye.

In order to maintain the balance of the typhoon in the atmospheric circulation, the greater the wind speed around the eye of the typhoon, the lower the pressure. When you enter the eye of the typhoon, the wind speed suddenly slows down, creating a calm state.

In addition, the geographical location of the eye of the typhoon also affects its calm state. If the eye of the typhoon is located in a sea area with a large water depth, the depth and temperature of the sea water are relatively stable, and it is not easily affected by the strong winds of the typhoon, resulting in a more significant state of calm and waves. If you are in an area where the bottom of the sea is inclined and the water depth is constantly changing, when a typhoon blows through the strong wild wind, a vortex will occur at the bottom of the seawater, and large waves will be generated, which will weaken or disappear the calm state of the waves.

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 pipe surrounded by a cloud wall, the air inside does not rotate, and the wind is very weak.

Although the weather was good in the eye of the typhoon, the waves at sea were very rough. This is due to the fact that the air bench at the center of the typhoon is carefully pressed, and it is very low compared to its surroundings. Therefore, in the place where the typhoon center landfalls, it often causes high tides and causes great damage, and the typhoon is a warm low pressure, so the surface flow field within the typhoon range is a cyclonic convergence flow field.

According to the magnitude of the convergence velocity, the lower level of a mature typhoon can be divided into three regions along the meridional direction

1) Outer ring: from the edge of the typhoon to the outer edge of the maximum wind speed area, the wind speed increases sharply to the center, the wind force is above level 6, and the radius is about 200-300 kilometers;

2) Middle Circle: From the outer edge of the maximum wind speed area to the eye wall of the typhoon, it is the area with the strongest convection and wind and rain in the typhoon, with a radius of 100 km;

3) Inner ring: that is, the eye area of the typhoon, the wind speed decreases rapidly, and the radius is about 5-30 km.

The eye of a typhoon, the center of a typhoon, is a strong weather system that occurs over a tropical ocean, with a gradual increase in wind speed from the periphery to the center, and then a rapid increase, but in the central area with a diameter of tens of kilometers, the wind decreases rapidly, the rain stops, and a cloudy sky with sunlight during the day and stars visible at night.

The typhoon center (typhoon eye) is the unique "eye" of tropical cyclones, which is called the typhoon eye in meteorology. If you cut the typhoon horizontally, you can see that there are three distinct areas, from the center to the outward: the typhoon eye area, the cloud wall area, and the spiral rain belt area.

Typhoon eye areaIt is very peculiar, there is little wind there, the weather is sunny, and the average diameter is 40 kilometers.
