Explanation: The north-east monsoon is a significant weather system in the Indian subcontinent, particularly affecting the southern and eastern parts of India. It is characterized by winds that blow from the north-east towards the south-west, primarily during the winter months (October to December). The monsoon originates from the north-eastern region of the Indian subcontinent and passes over the Bay of Bengal, which is a large body of water that lies to the east of India.
The Bay of Bengal plays a crucial role in the north-east monsoon system. As the winds pass over the warm waters of the Bay of Bengal, they pick up moisture, which is then released as rainfall when the winds reach the land. This is why the Coromandel coast, which is the eastern coast of the Indian peninsula, receives significant rainfall during the north-east monsoon. The Coromandel coast includes states such as Tamil Nadu, Andhra Pradesh, and parts of Odisha.
It is important to distinguish the north-east monsoon from the south-west monsoon, which is the primary monsoon system in India and brings the majority of the rainfall to the subcontinent during the summer months (June to September). The south-west monsoon originates from the Arabian Sea and the Bay of Bengal, moving towards the north-west, and is responsible for the monsoon season in most parts of India.
The north-east monsoon, on the other hand, is a secondary monsoon system that is less intense but still significant, especially for the southern and eastern regions of India. It is a critical source of water for these regions, particularly for agriculture and other water-dependent activities. Understanding the path and impact of the north-east monsoon is essential for predicting weather patterns, managing water resources, and planning agricultural activities in these regions.
In summary, the north-east monsoon passes over the Bay of Bengal, which is the correct answer to the question. This path is crucial for the moisture content of the winds and the subsequent rainfall in the southern and eastern parts of India.
