Consider the following statements comparing cyclone & anticyclone :
1. When a cyclone approaches there is a rise in the barometric reading, while an anticyclone causes barometric reading to fall.
2. The isobars are closer in a cyclone when compared to that in an anticyclone.
3. In northern hemisphere cyclonic circulation is clockwise, while anti-cyclonic circulation is clock-wise in
southern hemisphere.

Consider the following statements comparing cyclone & anticyclone ...
Correct Answer :- d
Explanation :- Barometers are used to predict the weather. A barometer measures air pressure: A "rising" barometer indicates increasing air pressure; a "falling" barometer indicates decreasing air pressure. Therefore, anti-cyclone approaches.
Anticyclones are so called because they have a flow opposite to that of cyclones—i.e., an outward-spiralling motion, with the winds rotating clockwise in the Northern Hemisphere and counterclockwise in the Southern.

Understanding Cyclones and Anticyclones
When comparing cyclones and anticyclones, it's crucial to analyze each statement carefully to determine their accuracy.
Statement 1: Barometric Readings
- In a cyclone, as it approaches, there is a fall in barometric pressure. This leads to the characteristic stormy weather associated with cyclones.
- Conversely, an anticyclone is associated with rising barometric pressure, leading to clear skies and calm conditions.
Statement 2: Isobar Proximity
- The isobars, which represent areas of equal pressure on a weather map, are indeed closer together in a cyclone than in an anticyclone. This proximity indicates a stronger pressure gradient and thus stronger winds associated with cyclones.
Statement 3: Circulation Direction
- In the Northern Hemisphere, cyclonic circulation is counterclockwise, while in the Southern Hemisphere, it is clockwise.
- On the other hand, anticyclonic circulation is clockwise in the Northern Hemisphere and counterclockwise in the Southern Hemisphere.
Conclusion
Evaluating the statements:
- Statement 1 is incorrect.
- Statement 2 is correct.
- Statement 3 is also incorrect.
Thus, the statements that are incorrect are 1 and 3, making the correct answer to the question option D: None of the above. The confusion arises from the misinterpretation of circulation directions and pressure changes associated with cyclones and anticyclones.
