Types of Monsoon in India
The southwest monsoon:
- This southwest monsoon is caused by an intense low-pressure system that develops over the Tibetan Plateau due to the region's extreme summer temperatures.
- They transport much moisture with them when they cross the warm equatorial currents.
- The rain begins to fall when these winds hit or impact the mountain barriers.
- After crossing the equator, these southeast trade winds move over the Arabian Sea and the Bay of Bengal before being snagged by the airflow over India.
- They go southwestward after passing the equator.
- The southwest monsoon is named as a result.
- The monsoon season's winds bring heavy rains to the region.
The northeast monsoon
- In this monsoon type, the wind blows from the sea to the land.
- Monsoon winds carry moisture from the Indian Ocean.
- The Northeast Monsoon affects only South India; from October to December, it rains in Tamil Nadu, Puducherry, Karaikal, Yanam, Andhra Pradesh, Kerala, Mahe, and south interior Karnataka.
- Also known as accompanying rains, low-pressure systems, depressions and cyclones cause the winter monsoon.
- Tamil Nadu experiences 48% (447.4 mm) of its annual rainfall during these three months, making it the state's primary rainy season.
