Short Note on the Southwest Monsoon and the Northeast Monsoon
Southwest Monsoon is caused because of intense heating during the summers. The intense heating causes the low-pressure formation over the Tibetan Plateau. The Southwest Monsoon winds are responsible for bringing out heavy rainfall to most parts of India. While the northeast monsoon winds result in rainfall on the southeast coast of India, particularly in Seemandhra’s south coast and Tamil Nadu coast.
Factors influencing the Southwest Monsoons
The factors that influence the Southwest Monsoons are as follows-
- Intense low-pressure formation over the Tibetan Plateau.
- Subtropical jet stream.
- Inter-Tropical Convergence Zone.
- Tropical easterly jet or African Easterly jet.
- Permanent high-pressure cell in the South of the Indian Ocean.
Factors influencing the Northeast Monsoons
The factors that influence the Northeast Monsoons are as follows-
- High-pressure cells in the southern parts of the Indian Ocean migrate to the west and gradually weaken.
- Migration or shift of Inter-Tropical Convergence Zone to southern India.
- Formation and strengthening of the high-pressure cells of Siberian and Tibetan Plateaus during winters.
