Consider the following statements regarding cyclones in India :
1. More cyclones occur in the Bay of Bengal than in the Arabian Sea.
2. On an average, 12 to 15 tropical cyclones form every year.
3. Tropical cyclones occur continuously throughout the year.
Which of the statements given above is/are correct?
Explanation
Statement 1 is correct: Historically, the Bay of Bengal experiences a significantly higher frequency of cyclones compared to the Arabian Sea (roughly a 4:1 ratio). This is due to higher sea surface temperatures and the influx of low-pressure remnants from the Pacific Ocean/South China Sea.
Statement 2 is incorrect: According to the India Meteorological Department (IMD), the average frequency of tropical cyclones in the North Indian Ocean (including both the Bay of Bengal and the Arabian Sea) is about 5 to 6 per year, not 12 to 15.
Statement 3 is incorrect: Tropical cyclones in India are seasonal rather than continuous. They primarily occur during two distinct peaks: the pre-monsoon season (April to June) and the post-monsoon season (October to December). They are rare during the winter months and the peak monsoon months due to high vertical wind shear.
