Whether the vortex in the Northern Hemisphere rotates clockwise or counterclockwise

You must be mistaken, the vortex in the northern hemisphere is definitely counterclockwise, only in the southern hemisphere it is clockwise, which is caused by the geostrophic deflection force, the northern hemisphere is biased to the right, the southern hemisphere is biased to the left, there is no vortex at the equator because there is no geostrophic deflection force at the equator.

What I see is also clockwise, even if you use your hand to interfere with it counterclockwise, it will still be clockwise after a while, why Shepiro is stupid I have to say that it is counterclockwise, and also gives a "plausible" explanation.

The Northern Hemisphere must be counterclockwise, because of the retraction deflection force, the Northern Hemisphere is deflected to the right.

The direction of the vortex in the northern and southern hemispheres is different.

In the Northern Hemisphere, it's counterclockwise, and in the Southern Hemisphere, it's clockwise. In the Northern Hemisphere, objects moving in a north-south direction will be deflected to the right, which is affected by the geostrophic deflection force.

In fact, it is not only this, the right bank of the river is washed by the current to a much higher extent than the left bank; The winds blowing from north to south on the earth always turn to the east wind; The rotation of tornadoes is due to the influence of geostrophic deflection forces. Physics calls this force the Coriolis force.

Take a bath, for example, it's a very common thing. However, Professor Shepiro, chair of the Department of Mechanical Engineering at the Massachusetts Institute of Technology in the United States, is keenly aware that every time the bath water is released, the swirl of the water always rotates in a counterclockwise direction.

Why is that? Shepiro clung to this question mark and carried out repeated experiments and studies. In 1962, he published **, arguing that this kind of vortex is related to the rotation of the earth, and if the earth stops rotating, this kind of vortex will not be produced, because the earth is constantly rotating from west to east, and the United States is in the northern hemisphere, so the bathwater rotates in a counterclockwise direction, and the typhoon in the northern half of the road also rotates in a counterclockwise direction, and the reason is the same as the vortex of bathwater water.

He also asserted that if in the Southern Hemisphere, the whirlpool of bathwater would rotate in a clockwise direction, at the equator, no whirlpool would form. His insight aroused great interest among scientists from all over the world, who conducted experiments in various places, and the results proved that Shepiro's conclusions were completely correct.

Also, because the vortex on Earth is formed by the deflection force of the Earth's rotation when the liquid moves, the rotation of typhoons is similar. At the equator, the rotational deflection force is zero, so a vortex cannot be formed. Similarly, there is no typhoon at the equator.

The water vortex in the Northern Hemisphere rotates in a clockwise direction. Vortex, when flushing a toilet bowl, the water flow creates a vortex flow under the drain empty. It has been theorized that in the Northern Hemisphere, the water vortex is directed in the direction of the water vortex in the Northern Hemisphere; In the Southern Hemisphere, it rotates counterclockwise.

And the reason for this phenomenon is due to the rotation of the earth. It has been theorized that in the Northern Hemisphere, the vortex is clockwise; In the Southern Hemisphere, it rotates counterclockwise. And the reason for this phenomenon is due to the rotation of the earth.

If our watch is transparent, so we look at the back of the watch, it is obvious that the hands of the watch have become counterclockwise rotation, if you can't understand, you can put the watch against the mirror**, the watch hands in the mirror are counterclockwise rotation. So if you change the position of the observation, then the so-called clockwise versus counterclockwise will change.

The same is true for the rotation of the earth, if we are directly above the North Pole to observe the rotation of the earth (first of all, we must know that the earth rotates from east to west) it is obvious that the earth is rotating clockwise, then please imagine the earth as a watch, at this moment we are observing at the North Pole of Qingshanyuan, what we see is the front of the watch, if you go to the south pole to observe the rotation of the earth, it is like looking at the back of this watch, if you have understood the first paragraph, then the so-called counterclockwise rotation is also understood. The so-called positive and negative changes are actually just a change in the perspective of your observation.

Tropical depression.

In the middle of the cyclone is the center of low pressure, low pressure in the middle, high pressure around it, high pressure straight to low pressure, and the northern hemisphere is deflected by geostrophic deflection force.

The influence of the Northern Hemisphere is right-sided, so it forms a counterclockwise rotation. (For details, please refer to the Senior 1 Geography textbook, which has a clear illustration).

The cyclone is an updraft, and the cyclone is low pressure, and the surrounding pressure is higher than the central pressure, so the flow direction of the air flow is the center of the periphery, because it is in the northern hemisphere, the geostrophic deflection force is to the right, so the formation of the air flow direction is counterclockwise, as shown in the figure below.

The Northern Hemisphere rotates counterclockwise.

Geostrophic deflection force is a force that causes a moving object on the earth's surface to experience a force perpendicular to the direction of its motion due to the rotation of the earth. The full name is the Earth's rotational deflection force. The geostrophic deflection force does not change the velocity (magnitude of velocity) of a moving object on the earth's surface, but it can change the direction of a moving object.

Geostrophic deflection forces have obvious effects on monsoon circulation, air mass movements, cyclone (typhoon) and anticyclone (cold air) migration paths, ocean currents and river movements, and many other natural phenomena.

Because except for the north and south poles, the angular velocity of each latitude is the same, when flying from north to south, the circle of the south is larger, that is, the longer the latitude line is to the south, so the linear velocity is large, so a small linear velocity in the north is slower than the linear velocity of the south, so it is biased to the right due to inertia. The same goes for the north, from the fast place to the slow place, the speed is "ahead", and the direction of progress is also deviated to the right.

Water vortices are counterclockwise in the Northern Hemisphere.

When scientist Kapiro poured sewage into the sink after each experiment, he found that the whirlpool formed at the leak always rotated in a fixed direction. He made many different shapes of leaks, but the results were always the same. So he went around the world to do the same experiment, and found that in the southern hemisphere the direction of the current vortex is exactly the opposite of that in the northern hemisphere, counterclockwise in the northern hemisphere and clockwise in the southern hemisphere, almost half of both cases near the equator.

Later, people called this phenomenon the "Capiro phenomenon".

In the 40s of the 20th century, the scientist Kapiro noticed that the vortex formed at the leak always rotated in a fixed direction when he poured sewage into the sink after each experiment, and this phenomenon attracted his attention. So he deliberately stirred his fingers in the opposite direction when the water flowed, but the vortex returned to its original direction of rotation after the hand left. Does this have anything to do with the shape of the drain?

So he made many different shapes of leaks, but the results were always the same. Puzzled by this, he traveled all over the world to do the same experiment, and to his great amazement, the direction of the current vortex in the southern hemisphere was exactly opposite to that in the northern hemisphere, counterclockwise in the northern hemisphere and clockwise in the southern hemisphere, almost half of both cases near the equator. Capiro was overjoyed, and he finally found the conclusion that the direction of the original vortex was related to its position on Earth.

Later, people called this phenomenon the "Capiro phenomenon".

In fact, the Capilo phenomenon is caused by a so-called Coriolis force caused by inertia during the rotation of the Earth. In the Northern Hemisphere, this deflection force is to the right, causing the water to form a counterclockwise vortex as it flows downward. In the Southern Hemisphere, it is just the opposite clockwise.

Another form of Capillo phenomenon in nature is tornadoes. Whether it is landspouts and seaspouts produced in the vast plains or the vast oceans, it is found that in the Northern Hemisphere their direction of rotation is mostly counterclockwise. The Foucault pendulum in the Beijing Planetarium rotates clockwise every 37 hours and 15 minutes, which is also the result of the Coriolis force.

The Coriolis force is an important force that is easily overlooked by the average person. For example, the pressure on the right track is greater when the train travels rapidly from south to north in the northern hemisphere, and the east bank of the river from south to north is more heavily scoured, all of which can be explained by the Coriolis force, and the influence of the Coriolis force should also be taken into account in the launch of long-range missiles, weather forecasting, navigation, and the design of bubble levels in aviation.

Physicists' understanding of the Coriolis force or the Coriolis effect is absolutely accurate, but using the Coriolis effect to explain the vortex of toilet bowl water is a big mistake. The Coriolis effect is true when explaining fluids that move on a large scale, such as ocean currents and atmospheric circulation. However, the Coriolis effect has little effect on the flow of water from flush toilets.

The two ends of the toilet bowl rotate the water flow, and the effect caused by the rotation of the earth is almost exactly the same, and even if there are slight differences, it is safe to cause a strong water flow. (The flow of water in small holes is established, but it is not possible to create a fast whirlpool).

This is a fallacy, a pseudoscience.

The geostrophic deflection force mainly has a very obvious influence on the airflow, which is the main reason for atmospheric motion. Cyclones and anticyclones, which are important weather features on Earth, require geostrophic deflection to form. Geostrophic deflection is also one of the main reasons for the formation of storms, one of the main reasons for the formation of trade winds in different latitude zones, and one of the main reasons for the formation of monsoons.

Geostrophic deflection forces are also one of the main reasons for the formation of ocean currents. Ocean currents are affected by geostrophic deflection and deflection in the process of flow, gradually forming a circulation, so that the earth's seawater heat and components can be exchanged, and the balance of global heat and water is maintained. The circulation in the Northern Hemisphere is clockwise, and the circulation in the Southern Hemisphere is counterclockwise.

However, scientists have said that the direction of the water vortex has nothing to do with the geotropic bias, and the geostrophic deflection is not able to affect the formation of the water vortex, and the movement direction and mode of existence of the water vortex on the earth are only related to the geomorphological characteristics; In the case of sewers, it has nothing to do with the structure and temperature of the sewers, but not with the rotation of the earth, so it is a fallacy that the direction of the water vortex in the northern and southern hemispheres is reversed, that is, whether in the southern or northern hemispheres, the direction of the water vortex may be clockwise or counterclockwise.

If the geostrophic deflection force affects the water vortex, then we should also be affected by the geostrophic deflection force when we play basketball and throw the javelin, but in fact it is not. If the water rotates a little clockwise at the beginning, when the water gradually leaks, the angular velocity will inevitably increase due to the conservation of angular momentum, and we will also see the water vortex. Assuming that the bottom of the tank is completely level and there is no disturbance in the water at all, the water will flow directly downwards wherever it is, without whirlpools.

So, there is no such thing as clockwise flowing down in the northern hemisphere, counterclockwise in the southern hemisphere. If the current vortex is directly related to the geostrophic deflection force, then the current vortex on the equatorial line has no direction.

Rotate counterclockwise into a vortex.

Counterclockwise. Due to the rotation of the earth from west to east, all objects that move horizontally on the earth must be deflected, such as wind, flowing water, etc.

The law of deflection is that the northern hemisphere is biased to the right and the southern hemisphere is biased to the left, so the northern hemisphere should rotate counterclockwise (like the cyclone in the northern hemisphere) and the southern hemisphere should rotate clockwise into it (like the cyclone in the southern hemisphere).

The Earth's rotation exerts a geostrophic deflection force perpendicular to the direction of motion of moving objects except the poles of the equator, with the northern hemisphere to the left and the southern hemisphere to the right.

The rotation of the vortex is related to the scale (diameter).

Large-scale vortex is the balance of the pressure gradient force and the Coriolis force (the friction force and centrifugal force are also small, which can be ignored). Therefore, the Northern Hemisphere cyclone rotates counterclockwise and the anticyclone rotates clockwise.

Small-scale vortices, such as tornadoes, have a balanced pressure gradient force and centrifugal force, while the Coriolis force is negligible, so they can rotate clockwise or counterclockwise.

Since the vortex of water is small-scale, the Coriolis force can be ignored, so it can rotate clockwise or counterclockwise.

The vortex in the northern hemisphere is definitely counterclockwise, only in the southern hemisphere it is clockwise, which is caused by the geostrophic deflection force, which is biased to the right in the northern hemisphere and to the left in the southern hemisphere, and there is no vortex at the equator because there is no geostrophic deflection force at the equator.

When an object moves relative to the earth's surface, it is affected by a force called the geostrophic deflection force and changes direction, but the geostrophic deflection force is not a real force, but an inertial force.

Geostrophic deflection force is a force that cannot be ignored for aerospace and aviation, the geostrophic deflection force is most significant in the polar regions, and gradually weakens in the direction of the equator until it disappears at the equator, and the geostrophic deflection force is very small in daily life, which is negligible.

As for the direction of the water vortex, it is said that the northern hemisphere is counterclockwise and the southern hemisphere is just the opposite, due to the geostrophic deflection. Is this true?

Let's first look at what the geostrophic bias is: due to the rotation of the earth, there is a rotational bias in the motion of objects. Objects moving horizontally on the Earth, regardless of which direction they move, are deflected, to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
