Northeast Monsoon in India 

Season: The Northeast Monsoon generally occurs from October to December and is also known as the retreating/post-monsoon monsoon.

Withdrawal of Southwest Monsoon: It begins after the southwest monsoon withdraws from the Indian subcontinent, with the monsoon trough shifting southwards.

Pressure and Wind Pattern: Cooling of northern India creates a high-pressure system, causing relatively cold and dry continental winds to move towards Indian ocean

Moisture Gain: As these winds cross the Bay of Bengal, they pick up moisture and bring rainfall to parts of southeastern India.

Major Rainfall Region: Tamil Nadu receives a major share of its annual rainfall from the Northeast Monsoon, while parts of Andhra Pradesh and adjoining southeastern areas also receive significant rainfall.

Agricultural Importance: The monsoon is crucial for paddy cultivation and other crops in Tamil Nadu and adjoining regions, where Southwest Monsoon rainfall is relatively limited.

Overall Contribution: The Northeast Monsoon contributes around 10–15% of India’s annual rainfall, but its regional importance is much greater, particularly for Tamil Nadu’s water resources and agriculture.
