Q. With reference to the formation of Cyclones in India, consider the following statements:
1.The Arabian Sea has seen a decrease in wind shear in recent years, creating a more favorable environment for cyclone formation.
2.Warm sea surface temperatures are essential for cyclone formation because they create strong winds that help the storm to develop.
3.July-September is considered the peak season for cyclones in India.
4.Tropical cyclone is the main type of cyclones that affect India.
Which of the statements given above are correct?
Answer: B
Notes:
Explanation –
Statements 1 and 4 are correct. Reduced wind shear allows cyclones to maintain their vertical structure and intensify. Studies show a decrease in wind shear over the Arabian Sea, facilitating cyclone formation.
Tropical cyclones are the most common type affecting India, forming over warm ocean waters.
Statements 2 and 3 are incorrect. While warm sea surface temperatures are crucial for cyclone formation, they don’t directly create strong winds. These winds result from the pressure difference between the cyclone’s low-pressure center and the surrounding high-pressure areas.
The peak season for the cyclone formation is from April to May and September to November.
