How can corriolis accelleration be explained in north or south of Globe?

Answer 1

It has nothing to do with acceleration or force. Differences in velocity create the effect.

Answer 2

Coriolis showed that an acceleration acts on all bodies moving on the Earth’s surface.

If one looks along the axis of rotation in the direction that makes the rotation appear in the counterclockwise and places his left hand palm down with the fingers pointing in the direction of the rectilinear motion the thumb will point in the direction of the acceleration.


If one looks along the Earth’s axis from the North Pole, the rotation appears counter clock wise. Hence in the Northern Hemisphere, any body moving rectilinearly relative to any inertial system will deviate to the right (as viewed by a terrestrial observer) in the course of its motion, while in the Southern Hemisphere, it will deviate to left.

This deviation could be large or small, depending on the direction of motion with respect to the axis and on the linear velocity of the motion.

The deviation of the body can take place in the horizontal or vertical plane (with respect to the surface of Earth). The Coriolis acceleration is directed perpendicular to the Earth’s axis; hence, the deviation taking place in the horizontal plane is the greatest at the Poles and equal to zero at the equator.

The reverse is true for deviations in the vertical plane.

The deviation of bodies moving in the horizontal plane from their rectilinear path is the reason why the right side banks of rivers are eroded in the Northern Hemisphere, and the left banks in the Southern Hemisphere to the left.

All masses flowing into regions of low pressure deviate from the radial direction to the right in the Northern Hemisphere, (to the left in the Southern Hemisphere) and form cyclones. Thus cyclones in the Northern Hemisphere stir the air masses counter clockwise, and in the Southern Hemisphere clockwise.

As a result of the vertical deviation, a falling body does not fall exactly vertically. Such a body deviates from east to west.

Answer 3

Any and every acceleration is caused by a force.
The "Coriolis acceleration" is caused by the "Coriolis force".

The Coriolis force results from the rotation of the Earth and the law of conservation of [angular] momentum.


That said, the Coriolis force / "effect" is very small, so small, it is negligible for almost all the things we would deal with in our everyday lives. On a much larger scale, such as with large weather patterns (Hurricanes), the Coriolis effect plays some part, but to all those people who think that toilets will flush a different direction after crossing the equation...you are sorely mistaken.

Answer 4

Only with a great deal of difficulty!

Everything on earth is being accelerated due to the rotation of the planet. As you (or any object) move, that acceleration influences the motion. At the equator the acceleration is parallel to gravity so you don't notice it's effect. Off the equator, the Coriolis acceleration is not parallel to gravity. The effect is to create a "force" away from the equator. This means it is different from the north or south side of the equator.

Answer 5

By rotation of the planet.
