Coriolis Force
Q. Which of the following is correct about Coriolis Force?- Published on 20 May 16a. Coriolis Force affects only the large-scale movement of air in the atmosphere
b. Coriolis Effect is caused due to rotation of Earth and pressure difference between two points
c. Winds are deflected to the right in the Southern hemisphere
d. If it was not for the Earth’s rotation, global winds would blow in straight north-south lines
ANSWER: If it was not for the Earth’s rotation, global winds would blow in straight north-south lines
- The Coriolis effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect. Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time, such as large-scale movement of air in the atmosphere or water in the ocean.
- This force causes moving objects on the surface of the Earth to be deflected to the right (with respect to the direction of travel) in the Northern Hemisphere and to the left in the Southern Hemisphere.
