With reference to Cyclone which of the following statements is/are correct?
(I) The formation of a cyclone is caused by difference in air pressure.
(II) Most of the cyclones develop over warm ocean waters in the tropical regions.
(III) The Eye of the Cyclone has dense cloud cover and the lowest temperature.
Select the answer using the codes given below:
- A(II) only
- B(I), (II) and (III)
- C(I) and (II) only
- D(III) only
Solution & Step-by-step Explanation
Let's assess the statements:
* Statement (I) is correct: Cyclones are low-pressure systems, and atmospheric pressure gradients drive wind movement and storm formation.
* Statement (II) is correct: Tropical cyclones require warm ocean waters (typically greater than ) to develop and gain energy.
* Statement (III) is incorrect: The "Eye" of a tropical cyclone is a region of mostly calm weather, clear skies (not dense cloud cover), and sinking air, which makes it warmer compared to the surrounding eye wall.
Therefore, statements (I) and (II) are correct.
* Statement (I) is correct: Cyclones are low-pressure systems, and atmospheric pressure gradients drive wind movement and storm formation.
* Statement (II) is correct: Tropical cyclones require warm ocean waters (typically greater than ) to develop and gain energy.
* Statement (III) is incorrect: The "Eye" of a tropical cyclone is a region of mostly calm weather, clear skies (not dense cloud cover), and sinking air, which makes it warmer compared to the surrounding eye wall.
Therefore, statements (I) and (II) are correct.
