Consider the following statements regarding the upper-level atmospheric dynamics of Western Disturbances: 1. The Subtropical Westerly Jet Stream steers the Western Disturbances towards the Indian subcontinent during winter. 2. A northward shift of this jet stream in winter allows the Western Disturbances to penetrate deep into Central India. 3. The moisture for these disturbances is sourced from the Mediterranean Sea, Black Sea, and Caspian Sea. Which of the statements given above is/are correct?
