Consider the following statements regarding the winter atmospheric circulation over India:
- Western Disturbances are shallow cyclonic depressions originating over the eastern Mediterranean Sea and traveling eastward across the Middle East.
- The steering mechanism that brings these Western Disturbances to the Indian subcontinent is the Tropical Easterly Jet Stream.
- The precipitation brought by these disturbances is highly beneficial for the Rabi crops in the northwestern plains of India.
Which of the above statements are correct?
Correct answer: B
Explanation
Western Disturbances are shallow cyclonic systems that form over the Mediterranean and move eastward, and their winter rain and snow are vital for Rabi crops in the northwestern plains, so statements 1 and 3 are correct. They are steered into the subcontinent by the subtropical westerly jet stream, not the Tropical Easterly Jet, so statement 2 is wrong.
