Most of us know that Equator is an imaginary line on the Earth’s surface which divides the Earth into Northern Hemisphere and Southern hemisphere, but we hardly have any idea about the effects of Earth’s rotation on moving objects in these two hemispheres.
Anything which moves in the Northern hemisphere will experience a small turn to the right .
In southern hemisphere it is just opposite . Everything turns to the left . This is called “Coriolis effect.” This force is not effective on the Eqator itself .The coriolis force is zero here.
Eqator runs through Central Africa and many other places of the world dividing the Earth in two equal halves .
Recently we went to Nairobi –capital city of the Republic of Kenya . From there we went to Nanyuki town which is situated on the Equator- to experience this coriolis effect . There we came across a board where it was written that the Equator passes through this place which has latitude = ‘0’. That means we were standing on zero zone.
It was really very interesting to go through such a new experience. We don’t know many mysteries of our planet Earth . This was one of them .
One teacher was present there to explain “Coriolis effect” to us. He took the help of a bucket of water , a small stick and a funnel.
In Equator region he poured some water into the funnel closing it’s other end tightly and put the stick into it . Next he released the water from the other end. The water moved down steadily . The floating stick remained in a horizontal position into the water. It moved neither to the right nor to the left . As coriolis force was not effective there .
Now the teacher walked further- twenty feet away from the zero zone towards North . Again he poured some water into the funnel and put the stick into the water. Here a strange thing happened . While releasing the water from the other end the stick into the water immediately turned to the right and moved in a clockwise manner. The teacher said it happened due to Earth’s rotation . Earth rotates from east to west. ,so the tendency for any moving body on or above the earth’s surface such as a water current, is to drift sideways from its course.
The teacher came back to the zero zone again .
Next moment he stepped towards Southern Hemisphere to go further- twenty feet away from zero position . He repeated the same task again . This time the stick into the water turned left to move -in just opposite direction , in anti-clockwise manner .
We were really very surprised. Why this difference at all?
We were curious to know about this Coriolis theory and why it happened at twenty feet away from Latitude=”O” .
Later we realized that a minimum distance is needed to see this effect very clearly . The Coriolis effect cannot be experienced significantly from very near to the equater , though it starts from there only . This deflective effectis are present on all free-moving objects including the atmosphere and oceans
Coriolis force is a concequence of inertia ( acts by an. external force).On the earth an object that moves along a north-south path or longitudinal line, , will undergo apparent deflection to the right in the Northern Hemisphere and to the left in the Southern Hemisphere . There are two reasons for that :
Firstly earth rotates eastward. Secondly the tangential velocity of a point on the earth is a function of latitude .(This velocity is essentially zero at the poles and it attains a maximum value at the equator). The Coriolis deflection is therefore related to the motion of the object and the roation of the earth.
Coriolis force is proportional to the speed of rotation of the Earth . For further informations : ( http://en.wikipedia.org/wiki/Coriolis_effect ) can help us .
