Why does the Coriolis force only affect objects in horizontal motion?
The Coriolis force, also known as Coriolis force, is commonly translated as Coriolis force in Chinese. I think we can explain it in this way. Assuming that the Earths center is stationary (this is relatively simple, but considering the Earths revolution would be much more complicated, but the Earths revolution has little impact on the Coriolis Force, at least not on the phenomena we often see). Because every point on Earth moves in a circular motion around the Earths axis. Lets assume here that the Earths axis remains constant, meaning it always runs in one direction. Then, lets assume that the Earths angular velocity remains constant, meaning it doesnt spin faster or slower at the same time. In addition to the previous assumption (that the Earths center is stationary), the Earth is now abstracted as a sphere that rotates uniformly around a straight line passing through its center. So now every point on the sphere is in uniform circular motion around the Earths axis, and the radius of motion is the perpendicular line drawn from that point to the Earths axis. The distance from the intersection of the perpendicular line and the Earths axis to that point is the radius of motion. So now it is obvious that with different latitudes, the velocity of motion at each point on the surface varies (due to different radii), but the angular velocity of motion at each point on the surface is the same. So when an object moves from low latitudes to high latitudes (such as from the equator to the North Pole, corresponding to the situation in the Northern Hemisphere), its linear velocity decreases. But objects all have inertia, and they tend to maintain their linear velocity of motion. That is to say, when observing an object in a relatively stationary place (a reference frame relative to the ground), it will always have a tendency to move eastward during its northward movement The Coriolis force, also known as the Coriolis force, is commonly translated as Coriolis force in Chinese.
