Why does Coriolis force pull winds to the right in the Northern Hemisphere but to the left in the Southern Hem

Answer 1

It's a bit difficult to explain, but wind patterns actually blow sin straight lines between the equator andthe poles. What happens is that the rotation of the Earth in effect turns the Earth out from underneath the wind belts, which causes them to seem to slant.

Incidentally, not all wind belts slant in the same direction in each hemisphere. They alternate; in the Northern Hemisphere, the wind pattern extending from the Equator to about 30 degrees nortyh blows in one direction, while the pattern immediately above blows in the opposite direction. Another pattern begins at 60 degrees north and blows in the same direction as the pattern at the equator. The Southern Hemisphere is divided the same way.

The reason for this is that there are three individual wind belts in each hemisphere. Starting at the equator, the general air movement is toward the poles until around thirty degrees north and south. Between thirty and sixty degrees, air moves toward the equator, and between sixty degrees and the poles, air moves toward the poles again. As a result, the patterns are deflected in different directions.

Answer 2

North-South winds are shifted because an object on the earth does not have as much Eastward movement from the motion of the earth towards the poles. This results in an airborne object going from equator to the north pole gaining increasingly more eastward movement than objects below because they are going to the east at a slower rate (The airborne object maintains its original eastward movement from when it left the ground). This results in the appearance of the airborne object being forced to the East. When an object moves South from the equator, the same thing happens. But, since east is to the left instead, it appears the object is being forced to the left.

Answer 3

In fact, the coriolis force deflects the force in one direction only.Your right hand and left hand are interchanged in both the hemisphere.Imagine the following:
If you are standing on the north pole and are able to look at the rotation of the earth, it will be from right hand side to left hand side.But if you are looking the same , standing on the south pole, it will be from left side to right side.This is because your head and feet positions are in one direction in one pole and reversed in the other pole.So the deflections also seem to be different.
