Q. Consider the following statements:

1. An easterly jet stream flows over the southern part of the Peninsula in June.
2. They steer the tropical depressions into India.
3. The frequency of tropical depressions determine the rainfall pattern during the north-east monsoons.

Which of the above is / are correct?
Answer: Only 1 and 2
Notes: The pattern of pressure and winds as mentioned above is formed only at the level of the troposphere. An easterly jet stream flows over the southern part of the Peninsula in June, and has a maximum speed of 90 km per hour. The easterly jet stream steers the tropical depressions into India. These depressions play a significant role in the distribution of monsoon rainfall over the Indian subcontinent. The tracks of these depressions are the areas of highest rainfall in India. The frequency at which these depressions visit India, their direction and intensity, all go a long way in determining the rainfall pattern during the southwest monsoon period.
