Q. Consider the following statements about the Polar Vortex:
1.The polar vortex is a large, persistent low-pressure zone containing extremely cold air, confined over the polar regions by the polar-front jet stream.
2.It rotates clockwise over the North Pole and counter-clockwise over the South Pole.
Which of the statements given above is/are correct?
Answer: A
Notes:
Explanation:
- Statement 1 is correct: The polar vortex is a long-lasting low-pressure system with very cold air, maintained over the polar regions by the polar-front jet stream, which acts as a dynamic boundary separating cold polar air from warmer mid-latitude air.
- Statement 2 is incorrect: Due to the Coriolis force, the polar vortex rotates counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere, not the reverse.
