Why is the rotation of the earth responsible for the deflection of the direction of horizontally mov

Since the angular velocity is the same at all latitudes except for the north and south poles. In the Northern Hemisphere, when flying from north to south, the circle in the south is larger, that is, the longer the parallel is in the south, so the linear velocity is large, so a small linear velocity in the north is slower than the linear velocity in the south, so it deviates 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.

When observing the chloroplast with the lower epidermis of spinach leaves, it is found that the chloroplast in the upper right corner of the field of view will rotate counterclockwise with the circulation of the cytoplasm, and the object seen by the microscope is a virtual image formed by the objective lens and eyepiece after 2 magnifications, and this virtual image is actually an inverted image, that is, the actual position of the chloroplast in the upper right corner of the field of view on the glass slide is the lower left corner. This is generally clear to students above junior high school. However, most people mistakenly believe that the actual direction of rotation of the chloroplast is also inverted, that is, clockwise.

We often see that the water flows from the bathtub to the sewer to form a counterclockwise vortex, and the south bank of the Yellow River, Huai River, Yangtze River and Zhujiang River is much more washed by the current than the North Li Da Stall. The winds blowing from north to south on the earth always turn to the east wind; The tornado also rotates counterclockwise, and the climbing plants often spiral to the left as they ascend along the object being climbed. These are all because the earth is constantly rotating from west to east, and China is in the northern hemisphere, which produces a counterclockwise imitation centrifugal force when the earth rotates, to put it bluntly, these left-handed phenomena are thrown off by this centrifugal force!

In the Southern Hemisphere, the bathwater vortex will rotate in a clockwise direction, and at the equator, no whirlpools will form.

So the actual direction of rotation we see in the chloroplast is counterclockwise!

Under the influence of geostrophic deflection forces, objects moving horizontally will be biased to the right in the direction of motion in the northern hemisphere and to the left in the direction of motion in the southern hemisphere. The direction of the geostrophic deflection force is perpendicular to the direction of the object's motion.

The greater the velocity, the greater the geostrophic deflection force.

Only horizontal motion along the equator is not affected by geostrophic deflection forces.

Geostrophic deflection forces are also important reasons for the formation of cyclones and anticyclones. The direction of the air flow is different due to the different direction of the geostrophic deflection force in the northern and southern hemispheres. Anticyclones are clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere; The cyclone is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.

The previous answer does not at all explain why the direction of the wind from low latitudes (in the Northern Hemisphere) like high latitudes is southwesterly and not southeasterly, nor does it explain why winds along the latitude (non-equator) also have a tendency to deflecrate.

The geostrophic deflection complex force does not exist in the first place. It is an imaginary force. Look at the bai diagram:

Suppose there is a person standing at point A observing the movement of an object in the direction indicated by the head of the arrow, and another person standing in front of a point A outside the earth and also observing the movement of an object. At the beginning, the person at A sees the object moving in a direction due south. After some time, the person at A rotates with the Earth and turns to point B, and the direction of the object's motion does not change to the direction of the observer outside the Earth.

But for the observer on Earth, the position in which he was standing changed, and he saw that the object seemed to be deflected in a southwesterly direction. To explain this phenomenon, the concept of geostrophic deflection force is introduced.

What does the axis of the earth always tilt when it turns?

The north and south celestial poles can be said to be approximately the North Star.

What is the direction of rotation of the Earth?

From west to east, it is counterclockwise at the Earth's North Pole and clockwise (north and south) in the Southern Hemisphere.

The direction of revolution is the same].

Both of these questions are in the high school geography book, and please take a good look at the textbook.

The rotation is from west to east, and the revolution is counterclockwise.

The rotation of the earth and the tilt of the earth's axis have caused a variety of natural climatic environments on the earth (including the change of seasons, which is only one of them).

Due to the tilt of the Earth's axis, the direct point of the Sun is not on the equator for most of the year, and as a result of the rotation, the direct point of the Sun moves periodically between the Tropic of Capricorn throughout the year. As shown in the figure below: (using the Northern Hemisphere as a benchmark).

At the same time, the earth is an approximate sphere, and the uneven heating and the geostrophic deflection force caused by the rotation of the earth lead to the generation of different wind belts, and the joint action of the revolution produces a variety of climatic environments.

The four seasons in the temperate zone, the dry season and the rainy season in the tropics, the polar day around the polar regions, and the polar night.

The seasons alternate.
