Q. With reference to the Coriolis force that affects wind direction, consider the following statements:
Which of the statements given above is/are correct?
Q. With reference to the Coriolis force that affects wind direction, consider the following statements:
Which of the statements given above is/are correct?
The correct option is C 1 and 3 only
Explanation:
All three statements are correct.
Statement 1 is correct: The rotation of the earth about its axis affects the direction of the wind and this force is called the Coriolis force. It is directly proportional to the angle of latitude. It deflects the wind to the left direction in the southern hemisphere and the right direction in the northern hemisphere.
Statement 2 is incorrect: The higher the pressure gradient force, the more the speed of the wind and the larger the deflection in the direction of wind happens.
Statement 3 is correct: The force acts perpendicular to the pressure gradient force.
The pressure gradient force is perpendicular to an isobar.
