Monsoon and Rainfall in India
Monsoon and its duration in India
- Monsoon is a seasonal wind that brings heavy rainfall to the Indian subcontinent.
- The duration of the monsoon varies in different parts of India.
- The southwest monsoon, which is responsible for most of the rainfall in India, arrives in Kerala in early June and covers the entire country by mid-July.
- The monsoon starts retreating from northern India in early September and withdraws completely by early October.
Statement 1: The duration of the monsoon decreases from southern India to northern India.
- This statement is correct.
- The monsoon arrives in Kerala in early June and covers the entire country by mid-July.
- The withdrawal of the monsoon starts from northern India in early September and withdraws completely by early October.
- Therefore, the duration of the monsoon decreases from southern India to northern India.
Rainfall in the northern plains of India
- The northern plains of India are a fertile region that receives a significant amount of rainfall.
- The rainfall in this region is influenced by the Himalayan mountain range, which acts as a barrier to the monsoon winds.
- The amount of rainfall varies in different parts of the northern plains of India.
Statement 2: The amount of annual rainfall in the northern plains of India decreases from east to west.
- This statement is also correct.
- The eastern parts of the northern plains of India receive higher rainfall than the western parts.
- The reason for this variation is the influence of the Bay of Bengal branch of the monsoon winds.
- The Bay of Bengal branch brings more rainfall to the eastern parts of the northern plains of India, while the Arabian Sea branch brings less rainfall to the western parts.
- Therefore, the amount of annual rainfall in the northern plains of India decreases from east to west.
Conclusion
Both the statements given in the question are correct. The duration of the monsoon decreases from southern India to northern India, and the amount of annual rainfall in the northern plains of India decreases from east to west.
