Which of the following statements regarding cyclones and anti-cyclones is/are correct?
1. In the Northern Hemisphere, cyclones rotate counter clockwise and anticyclones rotate clockwise.
2. Cyclones are often associated with cloudy or rainy weather, whereas anticyclones are often associated with fair weather.
3. In the Southern Hemisphere, the cyclonic spiral will be clockwise because the Coriolis force acts to the left.
Select the answer using the code given below :
A.1 only
B.1 and 2 only
C.2 and 3 only
D.1, 2 and 3✓ Correct
Explanation
All three statements are correct. In the Northern Hemisphere, cyclones (low pressure systems) rotate counter-clockwise and anticyclones (high pressure systems) rotate clockwise due to the Coriolis effect deflecting moving air to the right. Cyclones bring rising air, cloud formation, and precipitation, while anticyclones involve descending air leading to clear, fair weather. In the Southern Hemisphere, the Coriolis force deflects to the left, so cyclones rotate clockwise and anticyclones counter-clockwise.
