How are the spiral nests in the sea formed, and how are the whirlpools in the sea formed?

The flow of water in both directions meets.

To put it simply, because of the centrifugal force, the surrounding water has to leave the center due to the centrifugal force. The vortex has nothing to do with water or not, and the same goes for oil. If you look at water as a whole, all rotating objects have a force to leave the center of rotation, which is the centrifugal force, so the surrounding water surface is higher than the center, which is a vortex.

The rotation of the earth mentioned above is a different matter, although it is correct, but it is not in line with the question.

Leaky, have you ever used a funnel? That's probably what it means.

There are strong currents in the ocean, and the trajectory of movement is constant.

Because the seabed is not flat, there will always be mountain plateaus on the bottom of the sea, when the top of these mountain plateaus is close to the sea surface or even stretches out of the sea to form islands, and these mountain plateaus are in the trajectory of ocean currents, this kind of topography will bring hindrance to the ocean currents, so that they go around or branch, due to the leeward effect, they will form whirlpools in the ocean at the leeward side of the mountain plateau.

One is the influence of the topography of the seabed, and the other is the influence of prevailing winds.

Yes. Ocean currents flow between groups of islands, and there are basins and ridges on the seabed.

It's not very clear, but I know one reason, there must be other reasons, I'll just say what I know.

There are strong currents in the ocean, and the trajectory of movement is constant.

When the top of these mountain plateaus is close to the sea surface or even stretches out of the sea to form islands, and these mountain plateaus are on the track of the ocean current, this kind of topography will bring obstruction to the ocean current, making it go around or branch, and due to the leeward effect, it will form a whirlpool in the ocean at the leeward of the mountain and the land ridge plateau.

Submarine hot and cold currents meet, air cold and warm meet, submarine dark ditches and so on.

It is supposed to be the result of the current, the water flowing over the island, forming a whirlpool just behind the island.

If the whirlpool is large enough, it will drift with the current.

When errands are cautious, submerged islands in the waters of Hae-hyo-liang can also cause whirlpools.

If there are no islands, it is due to monsoons and geostrophic deflection forces

Black holes are probably the scariest thing in the universe, and nothing can escape from them, not even the fastest rays. In the past, it was thought that such black holes must be in the universe outside the Earth, but recently scientists have discovered that there are also objects similar to black holes on Earth, especially in the southern Atlantic, where there are many eddies.

According to Einstein's theory of relativity, a cosmic black hole is encased in a sphere of light, and due to the density of the black hole, the gravitational pull in this region is very strong, causing light to propagate in orbit while still retaining the optical quantum equilibrium. They neither fall into the black hole nor escape, forming a photon layer at the edge of the black hole. Scientists from ETH Zurich in Switzerland and the University of Miami in the United States have found that some of the vortices are surrounded by cosmic black holes

There is a spray band that rotates around the whirlpool, but no liquid falls into it.

Now this is inexplicable, the more convincing statement is that there are a large number of combustible gases in the seabed, these gases have low melting points and boiling points, and they are easily soluble in water, and the properties of these gases cause many changes in the seabed, changes in pressure, changes in density, and so on. The vortex is also supposed to be related to the state of these gases.

When the object moves perpendicular to the earth's latitude on the earth's surface, the earth's rotation linear velocity changes with latitude, and due to inertia, the object will have a tendency to maintain the direction of movement of the original speed relative to the ground, which is called the geostrophic deflection force. In the Northern Hemisphere, the object moves from south to north, and the linear velocity of the Earth's rotation becomes smaller (at the equator.

The linear velocity is maximum), and the object is biased to the east due to inertia to keep the linear velocity constant, which is to the right relative to the direction of motion. When moving from north to south, the linear velocity of the Earth's rotation increases, so it deviates to the west and moves relatively.

The direction is also to the right. Therefore, when the object in the northern hemisphere moves, it is uniformly subjected to the rightward geostrophic deflection force. In the same way, objects are uniformly subjected to a leftward geostrophic deflection force when moving in the southern hemisphere.

Now if we look at the vortex created by this current, if there is no geostrophic deflection force, then the water flow will flow in a radial line from the center, and the direction of the inflow velocity will be directed towards the center. For example, on the equatorial line of Ecuador, the famous country of the equator, when the water was filled with a funnel, the water flow dropped vertically without forming a vortex. In the Northern Hemisphere, the inflow velocity is to the right, so the inflow velocity is directed to the center to the right, creating a counterclockwise vortex.

Similarly, a clockwise vortex is formed in the Southern Hemisphere.

It is probably caused by the current, the sea water flows over the island, forming a whirlpool just behind the island, and if it is large enough, the whirlpool will drift with the current.

Of course, submerged islands in the sea can also cause whirlpools.

If there are no islands, it is due to monsoons and geostrophic deflection forces

Formed by the gravitational pull of the Moon on the Earth.

Natural phenomena such as tsunamis and tornadoes can also be formed.

Vortex is commonly known as the rotational motion of a fluid mass called vortex. In nature, eddies are sometimes visible, such as tornadoes in the atmosphere, vortex areas behind bridge piers, vortices created during rowing, and so on. But more often than not, the presence of vortices is not easily perceived.

For example, when an object moves in a real fluid, a thin boundary layer is formed on the surface of the object, and each point in this thin shear layer is a vortex; Another example is the turbulent movement that exists in nature and is filled with eddies of different scales, which are indistinguishable to the naked eye. The eddies we can see are fluid masses moving over a wide range. The movement of fluids has a very complex and many factors, such as when we release the water in the pool, we can see the vortex, its?

If you want to explain it to an 8-year-old child in layman's terms, you can play a game with him. You ask him to run straight towards you with open arms, and when he comes to you, you reach out and take one of his hands, and he will naturally turn around you. In fact, vortices are created when a fluid encounters such a force.

When doing this game, please be safe and don't push too hard.
